20 0 of 125 6/30/ :47 PM Public Input No. 32-NFPA 13D-2016 [ New Section after ] TITLE OF NEW CONTENT Press-Connect Fitting- A permanent mechanical connection for joining copper tubing, steel and stainless steel pipe utilizing elastomeric seal or an elastomeric seal and corrosion-resistant grip ring or rings. Fitting connections are made with a pressing tool and jaws or rings approved by the fitting manufacturer for use in accordance with the product listing. Currently there is no definition for Press-Connect fittings in NFPA 13D. The term Press-Connect Fitting is used in both the IAPMO and ICC codes. The wide use of Mechanical type fittings has created the need to identify fittings such as Press-Connect and provide definitions to prevent confusion between mechanical fitting types and to help identify the correct standards these fittings are required to be listed to. This definition is proposed to prevent confusion within the industry and aligns definitions for these type fittings. This definition will also help to prevent incorrect terminology in the industry such as referring to Press-Connect fittings as Propress which we have all commonly seen. As the Manufacturer of Propress we do like that our brand name is the name used by those in the industry when referring to Press-Connect fittings, but we do want the industry to have the correct terminology of the fittings to avoid any confusion between manufactured products.

A specific example of an unlisted hanger that has been witnessed to fail is the talon clamp with nail. This hanger clamp has a lower melting point than the required sprinkler head activation temperature and actually caused an entire section of the system piping to collapse, rendering the sprinkler system ineffective. If listed hangers are required, this potential hazard can be avoided with little impact to the overall system cost, in keeping with the intent of the standard to provide affordable protection from fire for residents of one- and two-family dwellings.

(5) Sprinklers in closets containing ventless clothes dryers shall be of the intermediate-temperature classification or higher. Ventless clothes dryers placed within closets have the potential to raise ceiling temperatures above 100 F (38 C) for sustained periods of time, potentially weakening the operating mechanisms of ordinary temperature rated fire sprinklers over months or years of use, leading to inadvertent operations. While ventless clothes dryers have been used in Europe for many years, they are fairly new to the North American market, where vented clothes dryers have been the norm. More expensive than vented dryers, they generally incorporate condensers in a two-loop system to first heat some incoming air, allowing it to absorb moisture from the damp clothes, then continually condense the heated moist air to release the water before recirculating the resulting dry air within the clothes dryer. Unlike vented dryers, where moist heated air is exhausted to the building exterior, these devices capture the water to a drain or pan, while the heat from the condensing cycle is exhausted into the immediate area. The condensers in combination machines that both wash and dry the clothes are generally water-cooled, such that quantities of cold water are used to condense the moisture evaporated from the clothes during the drying cycle, and pumped away through the drain line. But the standalone dryer units are air-cooled, using the ambient air as a heat sink. While this heat can be dissipated in a large laundry room, it can be expected to raise the temperatures within a laundry closet to levels unacceptable for ordinary temperature rated sprinklers. All standalone ventless dryers in the market are reportedly of this type.

(FIGURE 2) Reasoning: The point of the allowance is to find a distance far enough away from an obstruction to clear the bottom of the obstruction and provide fire protection below it. On flat ceilings the B distance is static. In sloped applications the B distance changes each time you arrive at a new A distance. The equation does not work unless you already have the sprinkler in position. In Figure 2, the B distance is static and the designer or installer can arrive at a distance without first needing to know where the sprinkler is.

In the 2016 edition, this section was modified. The allowance to have a sprinkler 18" down was added. However there was a requirement added that it had to be enclosed by walls and a door. There are many small hallways that are technically compartments with openings with adequate lintels that usually have a light in the center and this would allow the light to not be an obstruction. This is not new language as this is how it read in the 2013 edition and prior.

71 4 of 125 6/30/ :47 PM Public Input No. 53-NFPA 13D-2016 [ New Section after ] Sprinklers shall not be required in an enclosed swimming pool room when provided with a minimum of one exit door exiting directly to the exterior. Enclosed swimming pools generally have a low or no fuel content much less than garages, porches and similar structures including other rooms within the dwelling that are exempt. The majority of the room is water. Limited access to ceiling sprinklers for the purpose of installation and maintenance is difficult. Unique ceiling skylights and or soffiting makes listing requirements difficult to achieve. Submitter Full Name: Maurice Pilette Organization: Mechanical Designs Ltd.

84 7 of 125 6/30/ :47 PM The following is the general pipe sizing method for straight-run systems connected to a city water main of at least 4 in. (100 mm) in diameter in accordance with (1): (1) The system flow rate shall be established in accordance with Sections 10.1 and 10.2, and it shall be determined that the flow allowed by the water meter meets or exceeds the system demand and that the total demand flow does not exceed the maximum flow allowed by the piping system components. (2) The water pressure in the street shall be determined. (3) Pipe sizes shall be selected. (4) * Pressure loss for a water meter, if any, shall be determined and deducted using one of the following: (5) (6) (7) Table (a) shall be permitted to be used, even where the sprinkler demand flow exceeds the meter's rated continuous flow. Higher pressure losses specified by the manufacturer shall be used in place of those specified in Table (a). Lower pressure losses shall be permitted to be used where supporting data are provided by the meter manufacturer. (8) Pressure loss for elevation shall be deducted as follows: (9) Building height above street (ft) = pressure loss (psi) (10) Building height above street (m) = pressure loss (bar) (11)* Pressure losses from the city main to the inside control valve shall be deducted by multiplying the pressure loss associated with the pipe material by the total length(s) of pipe in feet (meters). (12) Pressure loss for piping within the building shall be deducted by multiplying the pressure loss associated with the pipe material by the total length(s) of pipe in feet (meters). (13) Pressure loss for valves and fittings shall be deducted as follows: (14) The valves and fittings from the control valve to the farthest sprinkler shall be counted. (15) The equivalent length for each valve and fitting as shown in Table (b), Table (c), Table (d), or (a) Table (e) or or as specified by the manufacturer shall be determined and the values added to obtain the total equivalent length for each pipe size. The friction loss for a flow straight through tee or cross shall only be included in calculations performed in accordance with (b) The equivalent length for each size shall be multiplied by the pressure loss associated with the pipe material and the values totaled. (16) In multilevel buildings, the steps in (1) through (8) shall be repeated to size piping for each floor. (17) If the remaining pressure is less than the operating pressure established by the testing laboratory for the sprinkler being used, the sprinkler system shall be redesigned. (18) If the remaining pressure is higher than required, smaller piping shall be permitted to be used where justified by calculations. (19) The remaining piping shall be sized the same as the piping up to and including the farthest sprinkler unless smaller pipe sizes are justified by calculations.

92 5 of 125 6/30/ :47 PM Determination of the required size for water distribution piping shall be in accordance with the following procedure: (1) Step 1 Determine Psup. Obtain the static supply pressure that will be available from the water main from the water purveyor or from a private source, such as a tank system, a private well system, or a combination of these. For a private source, the available water supply pressure shall be based on the minimum pressure control setting for the pump. (2) Step 2 Determine PLsvc. Use Table (a) to determine the pressure loss in the water service pipe based on the selected size of the water service. (3) Step 3 Determine PLm. Use Table (a) to determine the pressure loss from the water meter based on the selected water meter size. Where the actual water meter pressure loss is known, PLm shall be the actual loss. (4) Step 4 Determine PLd. Determine the pressure loss from devices, other than the water meter, installed in the piping system supplying sprinklers, such as pressure-reducing valves, backflow preventers, water softeners, or water filters, taking into account the following: (5) Device pressure losses shall be based on the device manufacturer's specifications. (6) The flow rate used to determine pressure loss shall be the rate from Section 10.1, except that 5 gpm (20 L/min) shall be added where the device is installed in a water service pipe that supplies more than one dwelling. (7) As an alternative to deducting pressure loss for a device, an automatic bypass valve shall be installed to divert flow around the device when a sprinkler activates. (8) Step 5 Determine PLe. Use Table (b) to determine the pressure loss associated with changes in elevation. The elevation used in applying the table shall be the difference between the elevation where the water source pressure was measured and the elevation of the highest sprinkler. (9) Step 6 Determine PLsp. Determine the maximum pressure required by any individual sprinkler based on the following: (10) The area of coverage (11) The ceiling configuration (12) The temperature rating (13) Any additional conditions specified by the sprinkler manufacturer (14) Step 7 Calculate PLt. Using the equation in , calculate the pressure available to offset friction loss in water distribution piping between the service valve and the sprinklers. (15) Step 8 Determine the maximum allowable pipe length. Use Table (c) through Table (h) to select a material and size for water distribution piping. The piping material and size shall be acceptable if the developed length of pipe between the service valve and the most remote sprinkler does not exceed the maximum allowable length specified by the applicable table. Interpolation of Pt between the tabular values shall be permitted. Table (a) Water Service Pressure Loss (PLsvc) Flow Rate* (gpm) 40 ft or less 3 4 in.

100 3 of 125 6/30/ :47 PM Public Input No. 81-NFPA 13D-2016 [ New Section after ] Inactive Systems * In a detached dwelling or a manufactured home the sprinkler system shall be permitted to be put in an inactive state for any of the following reasons: (1) After a manufactured home has been installed and testing in the factory and is being prepared for shipment. (2) When a manufactured home is being stored for future occupancy. (3) When the detached dwelling is unoccupied during renovation work, with notification and approval of the AHJ. (4) When the detached dwelling is unoccupied for an extended period of time, with notification and approval of the AHJ Where a wet pipe system is installed and the piping will be subject to temperatures below 40 F (4 C) the piping and the stored water supply shall be drained * Residential pendent and sidewall sprinklers installed on drops, where the drops are 4 or less in length, the drops shall not be required to be drained Prior to the system being restored to service, the system shall be filled with water, pressurized to normal system pressure, and visually inspected for leaks Once the system has been restored to service, it shall be inspected and tested in accordance with section 12.2 of this standard. There needs to be guidance for taking a system out of service. There are many instances when an installed system needs to be taken out of service such as for shipping or storage of a manufactured home, or when extensive renovation or remodeling work is going on in the home, or when the home will be unoccupied for an extended period of time. NFPA 13D sprinkler systems are life safety systems and do not need to remain active when the home is being shipped, stored or is unoccupied. This guidance is especially needed when the detached dwelling or manufactured home is subject to freezing temperatures. Once the home is to be occupied again, the system must be tested for leaks and the system and components inspected and testing before restored to service.

103 6 of 125 6/30/ :47 PM NFPA 13D is appropriate for protection against fire hazards only in one- and two-family dwellings and manufactured homes. Residential portions of any other type of building or occupancy should be protected with residential sprinklers in accordance with NFPA 13 or in accordance with NFPA 13R. Other portions of such buildings should be protected in accordance with NFPA 13 or NFPA 13R as appropriate for areas outside the dwelling unit. The criteria in this standard are based on full-scale fire tests of rooms containing typical furnishings found in residential living rooms, kitchens, and bedrooms. The furnishings were arranged as typically found in dwelling units in a manner similar to that shown in Figure A.1.1(a), Figure A.1.1(b), and Figure A.1.1(c). Sixty full-scale fire tests were conducted in a two-story dwelling in Los Angeles, California, and 16 tests were conducted in a 14 ft (4.2 m) wide mobile home in Charlotte, North Carolina. Sprinkler systems designed and installed according to this standard are expected to prevent flashover within the compartment of origin where sprinklers are installed in the compartment. A sprinkler system designed and installed according to this standard cannot, however, be expected to completely control a fire involving fuel loads that are significantly higher than average for dwelling units [10 lb/ft 2 (49 kg/m 2 )] and where the interior finish has an unusually exhibits either a high flame spread index (greater than , corresponding to a Class C ) when tested in accordance with ASTM E84, Standard Test Method for Surface Burning Characteristics of Building Materials, or ANSI/UL 723, Standard for Test for Surface Burning Characteristics of Building Materials or a high heat release (such as a heat release rate exceeding 800 kw) when tested in accordance with NFPA 286.

In more modern terms the key concern is heat release and the best test for that for interior finish is NFPA 286. An interior finish material must exhibit a peak heat release rate not exceeding 800 kw and not reach flashover in the tests to be considered acceptable.

Underground pipe and fittings or tube acceptable under the applicable plumbing code is adequate to run from the remote system riser to the dwelling or home. In the scenario where the water supply source and the riser assembly is not in the dwelling unit, underground pipe and fittings may be needed to run from the riser assembly to the dwelling. FEMA uses this arrangement when providing sprinkler systems for many of their manufactured housing units. This arrangement could also be used when retrofitting an existing dwelling or home. The added text makes it clear that underground pipe and fittings do not have to be listed. However, in accordance with section 5.3 the underground pipe and fittings must comply with the applicable plumbing code for the dwelling or home.

Rather than having a pump and tank assembly as described in sections and which typically takes up floor space in the dwelling or home and requires a separate ac power source among other things, the well pump can be up-sized to accommodate the sprinkler demand at considerably less cost. While well pumps are an economical solution for a water supply in rural areas, many home builders aren t aware of this option. The additional annex text should help bring this option to the forefront and decrease the cost of the residential sprinkler system.

116 9 of 125 6/30/ :47 PM The connection to city mains for fire protection is often subject to local regulation of metering and backflow prevention requirements. Preferred and acceptable water supply arrangements are shown in Figure A.6.2(a)through Figure A.6.2(d). Where it is necessary to use a meter between the city water main and the sprinkler system supply, an acceptable arrangement as shown in Figure A.6.2(c)and Figure A.6.2(d)can be used. Under these circumstances, the flow characteristics of the meter are to be included in the hydraulic calculation of the system [see Table (a)]. Where a tank is used for both domestic and fire protection purposes, a low water alarm that actuates when the water level falls below 110 percent of the minimum quantity specified in should be provided. The effect of pressure-reducing valves on the system should be considered in the hydraulic calculation procedures. Figure A.6.2(a), Figure A.6.2(c), or Figure A.6.2(d)are acceptable methods for getting the water supply into the unit for a stand-alone sprinkler system (one that does not also provide direct connections to the cold water fixtures) because the common supply pipe for the domestic system and the sprinkler system between the water supply and the dwelling unit has a single control valve that shuts the sprinkler system, which helps to ensure that people who have running water to their domestic fixtures also have fire protection. This serves as a form of supervision for the control valve and can be used to make sure that the valve stays open in place of other, more expensive options such as tamper switches with a monitoring service. Some water utilities insist on separate taps and supply pipes from the water supply to the dwelling unit for fire sprinkler systems as shown in Figure A.6.2(d), due to concerns about shutting off the water supply for nonpayment of bills and the desire not to shut off fire protection if this ever occurs. While these types of arrangements are acceptable, they might not be cost efficient and should be discouraged due to the extra cost burden this places on the building owner. The concern over shutting off the water for nonpayment of bills is a nonissue for a number of reasons. First, the water utilities rarely actually shut off water for nonpayment. Second, if they do shut off water for nonpayment, they are creating violations of all sorts of health and safety codes, allowing people to live in a home without running water. Concern over the fire protection for those individuals when they are violating all kinds of other health codes is disingenuous. More likely, the water utility will not shut off the water and will follow other legal avenues to collect on unpaid bills, such as liens on property. Millions of people should not have to pay hundreds of millions of dollars to install separate water taps and lines for the few services that might get shut off.

More likely, the water utility will not shut off the water and will follow other legal avenues to collect on unpaid bills, such as liens on property. Millions of people should not have to pay hundreds of millions of dollars to install separate water taps and lines for the few services that might get shut off. a situation in which the dwelling would be unfit for occupation. As the purpose of an NFPA 13D system is life safety, an unoccupied dwelling would not require an active sprinkler system. Figure A.6.2(a) Minimum Requirements for a Stand-Alone System.

125 07 of 125 6/30/ :47 PM Public Input No. 74-NFPA 13D-2016 [ Section No. A ] A The best method for getting the water supply into the unit for a stand-alone sprinkler system (one that does not also provide direct connections to the cold water fixtures) is to have a common pipe for the domestic system and the sprinkler system between the water supply and the dwelling unit. Once inside the dwelling unit, the pipes can be split to provide the individual domestic and sprinkler systems. In this arrangement, a single control valve on the combined pipe (prior to the split) as shown in Figure A.6.2(a) being the only control valve that shuts the sprinkler system is preferred because it ensures that people who have running water to their domestic fixtures also have fire protection. This serves as a form of supervision for the control valve and can be used to make sure that the valve stays open in place of other, more expensive options such as tamper switches with monitoring service. Some water utilities insist on separate taps and supply pipes from the water supply to the dwelling unit for fire sprinkler systems due to concerns about shutting off the water supply for nonpayment of bills and the desire not to shut off fire protection if this ever occurs. While this type of arrangement is acceptable [see Figure A.6.2(b) ], it is not cost efficient and should be discouraged due to the extra burden this places on the building owner. The concern over shutting off the water for nonpayment of bills is a nonissue for a number of reasons. First, the water utilities rarely actually shut off water for nonpayment. Second, if they do shut off water for nonpayment, they are creating violations of all sorts of health and safety codes, allowing people to live in a home without running water. Concern over the fire protection for those individuals when they are violating all kinds of other health codes is disingenuous. More likely, the water utility will not shut off the water and will follow other legal avenues to collect on unpaid bills such as liens on property. Millions of people should not have to pay hundreds of millions of dollars to install separate water taps and lines for the few services that might get shut off. In a situation where a two-family dwelling or townhouse has a common water supply, there must be a way to isolate the sprinkler system in one unit without having to enter another unit. When each unit has its own, accessible shutoff valve and one unit suffers a fire event and cannot be occupied, the damaged unit can be isolated and other units can remain occupied because they have functioning sprinkler systems. Currently this section is an almost word-for word copy of the previous section. It doesn t seem as though the language needs to be repeated. The language on page 64 of the 13D/13R handbook in the handbook (Ask the AHJ) would be more appropriate to clarify this section.

128 10 of 125 6/30/ :47 PM Multipurpose piping systems consist of a single piping system within a residential occupancy that is intended to serve both domestic and fire protection needs. Basic forms of this system are shown in Figure A.6.3(a), Figure A.6.3(b), Figure A.6.3(c), and Figure A.6.3(d). A network system, as defined in , is a type of multipurpose system that utilizes a common piping system supplying domestic fixtures and fire sprinklers where each sprinkler is supplied by a minimum of three separate paths. In dwellings where long-term use of lawn sprinklers is common, provision should be made for such usage. The supply for the lawn sprinkler system should originate at the main system riser instead of being supplied from the combined fire sprinkler/domestic water pipe throughout the home.

Some may read this to mean that a drain valve at the system riser is required when a plumbing fixture meets the drain requirements called for in this section. The sprinkler system can be adequately drained from a plumbing fixture that is fed from the sprinkler system piping.

137 17 of 125 6/30/ :47 PM All residential sprinklers have been investigated under a flat, smooth, 8 ft (2.4 m) high horizontal ceiling. Some residential sprinklers have been investigated and listed for use under specific ceiling configurations such as a horizontal beamed ceiling. The performance of residential sprinklers under flat, smooth, horizontal ceilings has been well documented throughout the life of NFPA 13D. Prior to 2010, several manufacturers of residential sprinklers had performed testing and received listings for residential sprinklers under certain slopes and in certain beam conditions. In 2010, the Fire Protection Research Foundation (FPRF) conducted a research project consisting of 76 FDS simulations and 12 full-scale fire tests. The results have been used to develop system design criteria in a generic manner to simplify the use of residential sprinklers. Some residential sprinkler listings still exist for situations beyond the scope of the generic design. See the FPRF report, Analysis of the Performance of Residential Sprinkler Systems with Sloped or Sloped and Beamed Ceilings dated July 2010 for more information. Questions are frequently asked regarding the minimum two sprinkler design when certain sprinkler performance statistics have indicated that in a majority of the cases (with residential sprinklers) the fire is controlled or suppressed with a single sprinkler. While these statistics might or might not be accurate, the water supplies for the fire sprinkler systems under which these statistics were generated were designed for two or more sprinklers in the first place. When the fires occurred, the first sprinkler operated in excess of its individual design flow and pressure because the sprinkler system s water supply was strong enough to handle multiple sprinklers and only a single sprinkler opened. At these higher flows and pressures, the discharge from a single sprinkler was sufficient to limit or suppress the heat generated from the fire. This concept is called hydraulic increase. Hydraulic increase can also occur when a water supply s capabilities during the fire event exceeded that required by the minimum design requirements of the standard. Since none of the data used to generate the previously mentioned statistics captured the capabilities of the water supply in relation to the design requirements, the impact of the hydraulic increase on the number of single sprinkler activations cannot be determined. But if the minimum water supply requirement of the standard is reduced to only be capable of handling a single sprinkler, then there could be no hydraulic increase safety factor. When the first sprinkler opens, it will only get the flow and pressure that were originally designed for it, and the potential is significant for that to be insufficient to control the fire, given any obstructions and the layout of the space where the fire starts. The National Institute for Standards and Technology (NIST), under a grant from the United States Fire Administration, studied this concept several years ago in the hopes of being able to propose a singlesprinkler flow for the 2007 edition of NFPA 13D (see NIST Report NIST GCR prepared by Underwriters Laboratories with a publication date of February 2004). Unfortunately, the research did not support the design of a sprinkler system with only the flow for a single sprinkler, even under conditions of small rooms with flat, smooth ceilings. Without the hydraulic increase associated with the two-sprinkler design, the fire scenarios were too many where the first sprinkler to open would have insufficient flow to control the fire and then multiple sprinklers would open, causing the room to reach untenable conditions and the water supply to be overrun. These same fire scenarios were easily controlled by a sprinkler system designed for a two-sprinkler water supply from the start. In addition to the NIST tests, the National Fire Sprinkler Association conducted a series of full-scale fire tests in simulated bedrooms that were 14 ft 14 ft (4.2 m 4.2 m) with an adjoining hallway, each with flat, smooth, 8 ft (2.4 m) high ceilings. The tests were performed to determine better rules for keeping sprinklers clear of obstructions like ceiling fans, but baseline tests were also performed without any obstructions at the ceiling. In nine out of the twelve tests, including the two baseline tests without obstructions at the ceiling, a sprinkler in the hall outside the room of fire origin opened first, followed by the sprinkler in the room of origin. Even though the room of origin met all of the rules of NFPA 13D as a compartment, a sprinkler outside of this room was opening first. All of these fires were controlled by the sprinklers, but if the water supply had only been sufficient for a single sprinkler, the sprinklers might not have been able to provide fire control. For examples of selecting a compartment for consideration, see Figure A.10.2(a) and Figure A.10.2(b), which show examples of design configurations for compartments based on the presence of lintels to stop the flow of heat.

There needs to be guidance for taking a system out of service. There are many instances when an installed system needs to be taken out of service such as for shipping or storage of a manufactured home, or when extensive renovation or remodeling work is going on in the home, or when the home will be unoccupied for an extended period of time. NFPA 13D sprinkler systems are life safety systems and do not need to remain active when the home is being shipped, stored or is unoccupied. This guidance is especially needed when the detached dwelling or manufactured home is subject to freezing temperatures. Once the home is to be occupied again, the system must be tested for leaks and the system and components inspected and testing before restored to service.

At a recent ICC code hearing, there was extensive discussion about whether the 4-story limit in NFPA 13R relates to grade plane, as defined in the building code. It does not. Although the existing NFPA 13R text was thought to be clear that the 4-story limit is not with respect to grade plane (which is why "in height" was repeated in the existing scope text), it has become apparent that the existing text needs to be slightly adjusted to better convey this point. This is particularly important with respect to application of NFPA 13R to buildings that are constructed in accordance with pedestal building options under model building codes. Proper application of the standard to pedestal construction, consistent with this proposal, is clearly conveyed in the NFPA Residential Sprinkler Systems Handbook, but adjusting the scoping text should help to eliminate any remaining confusion.

Fitting connections are made with a pressing tool and jaws or rings approved by the fitting manufacturer for use in accordance with the product listing. Currently there is no definition for Press-Connect fittings in NFPA 13R. The term Press-Connect Fitting is used in both the IAPMO and ICC codes. The wide use of Mechanical type fittings has created the need to identify fittings such as Press-Connect and provide definitions to prevent confusion between mechanical fitting types and to help identify the correct standards these fittings are required to be listed to. This definition is proposed to prevent confusion within the industry and aligns definitions for these type fittings. This definition will also help to prevent incorrect terminology in the industry such as referring to Press-Connect fittings as Propress which we have all commonly seen. As the Manufacturer of Propress we do like that our brand name is the name used by those in the industry when referring to Press-Connect fittings, but we do want the industry to have the correct terminology of the fittings to avoid any confusion between manufactured products.

159 3 of 139 6/30/2016 1:23 PM Public Input No. 93-NFPA 13R-2016 [ Section No ] Rated Pressure. System components shall be rated for the maximum system working pressure to which they are exposed but shall not be rated at less than 175 psi (12.1 bar) for components installed above ground and 150 psi (10.4 bar) for components installed underground between the water supply and the system riser. When the underground piping can be supplied or pressurized by a Fire Department Connection (FDC), the underground piping shall be designed to withstand a working pressure of not less than 200 psi (Class 200), or 50 psi greater than the system design pressure, whichever is greater. This PI intends to require higher pressure ratings for underground lines that can be fed by Fire Department Connections. Delivery of water at Fire Department Connections can cause pressures that exceed 150 psi. Typically, use of 200 psi rated line can withstand the pressures delivered at the FDC. However, when higher pressures are required at the FDC due to system demands, the underground line is required to be listed for 50 psi above that demand pressure. The 50 psi above design pressure is to allow for pipe to be listed for the pressure used during the hydrostatic test.

162 6 of 139 6/30/2016 1:23 PM Public Input No. 86-NFPA 13R-2016 [ New Section after ] Nonmetallic pipe used in isolated portions of wet pipe sprinkler systems where that portion of the system is provided with a pressure-reducing valve set to no more than 80 psi (5.5 bar) shall be designed to withstand a working pressure not less than 130 psi (9 bar) at 120 F (49 C) and 100 psi (6.9 bar) at 180 F (82 C). By requiring that system components be rated at 175 psi an assurance is made that there will be no failures due to excessive pressure in the system coming either from a fire pump or from a fire truck when they arrive on scene and hook up to the fire department connection on the outside of the building. The purpose of the fire department connection is both to provide a reliable water supply to supplement the sprinkler system and to provide water pressure and flow in the standpipe for fire department hose connections. There is no reason for the sprinkler system to have excessive pressure applied to the sprinklers themselves, simply providing a sustainable water flow is enough. Therefore, limiting the pressure to 80 psi with the use of pressure reducing valves will not have a negative impact on the performance of the sprinkler system. In fact in many cases there are reduced pressure zone valves coming off standpipes for the sprinkler system on each floor already. If the pressure is limited to 80 psi for each zone/area utilizing a non-metallic type of pipe that doesn t have the 175 psi pressure rating there should be no issues allowing the use of these types of pipes in 13R applications. Precedence for this has been set in NFPA 13D with the allowance of a wet pipe standalone sprinkler system utilizing non-metallic pipe that has a listed pressure below 175 psi as long as the pressure was limited to no more than 80 psi.

In many residential buildings, there are private garages that exceed 400 square feet. However, many of these garages are protected with residential sprinklers or standard sprinklers with a.05 density. These concealed spaces are generally wood floor trusses with dwelling units above. The concealed space itself is technically light hazard and in most cases it is a rated assembly. In the spirit of providing life safety verses property protection, non metallic piping should be allowed to run in these spaces even when the room is greater than 400 square feet.

New Section is a clarification and makes NFPA 13R consistent with Section of NFPA 13. In residential buildings with ordinary hazard rooms larger than 400 square feet, the installer is required to transition from listed nonmetallic pipe to metallic pipe. New Section eliminates that issue. The requirement to install the pipe or tube within a 1-hour fire resistance-rated assembly will insure the integrity of the piping systems until the sprinkler heads activate.

175 9 of 139 6/30/2016 1:23 PM Public Input No. 100-NFPA 13R-2016 [ New Section after ] TITLE OF NEW CONTENT Type your content here... Sprinklers in closets containing ventless clothes dryers shall be of the intermediate-temperature classification or higher. Ventless clothes dryers placed within closets have the potential to raise ceiling temperatures above 100 F (38 C) for sustained periods of time, potentially weakening the operating mechanisms of ordinary temperature rated fire sprinklers over months or years of use, leading to inadvertent operations. While ventless clothes dryers have been used in Europe for many years, they are fairly new to the North American market, where vented clothes dryers have been the norm. More expensive than vented dryers, they generally incorporate condensers in a two-loop system to first heat some incoming air, allowing it to absorb moisture from the damp clothes, then continually condense the heated moist air to release the water before recirculating the resulting dry air within the clothes dryer. Unlike vented dryers, where moist heated air is exhausted to the building exterior, these devices capture the water to a drain or pan, while the heat from the condensing cycle is exhausted into the immediate area. The condensers in combination machines that both wash and dry the clothes are generally water-cooled, such that quantities of cold water are used to condense the moisture evaporated from the clothes during the drying cycle, and pumped away through the drain line. But the standalone dryer units are air-cooled, using the ambient air as a heat sink. While this heat can be dissipated in a large laundry room, it can be expected to raise the temperatures within a laundry closet to levels unacceptable for ordinary temperature rated sprinklers. All standalone ventless dryers in the market are reportedly of this type.

A During construction, alternation and demolition, there are many hazardous conditions, such as cutting, welding, grinding and hazardous product storage that can be made safer by installing a temporary fire sprinkler system. Without this section, there would be no allowance in NFPA 13R to permit such systems because they would not fully comply with the provisions of the standard. Given that such protection would be supplemental to any other protection that would be required, there is no harm in allowing this additional safety feature on a temporary basis if the design and installation is considered reasonable by the AHJ. There is a history of major fires during construction that were associated with hazardous conditions during construction. In some cases, developers will consolidate hazardous operations, such as a welding or grinding area, in a designated area of a building to increase control of the operation. Site managers will sometimes provide temporary sprinkler systems to supplement fire extinguishers and other safety features (not diminishing any other required protection feature) to improve safety, but there have been cases where AHJs have ordered these systems removed because they aren't currently permitted by NFPA 13 or NFPA 13R. Given that it's better to have some protection, as approved by the AHJ, vs.prohibiting an additional measure of safety, this proposal adds an allowance in NFPA 13R to permit temporary installations. A parallel proposal is being submitted to NFPA 13.

202 2 of 139 6/30/2016 1:23 PM Public Input No. 95-NFPA 13R-2016 [ Section No ] When Protection of Fuel-Fired Equipment. Where protection of fuel-fired equipment is present, at required by 6.6.4, and 6.6.7, sprinkler protection shall be provided in accordance with the following: (1) At least one quick-response intermediate temperature sprinkler sprinkler with a minimum k-factor of 5.6 shall be installed provided above the fuel-fired equipment. Sprinklers shall be sufficient to cover the fuel-fired equipment protection area, which is equal to the entire perimeter of the fuel-fired equipment when viewed on a plan view. (2) Where the sprinkler(s) protecting the fuel-fired equipment is located under a ceiling with slope equal to or greater than a 4:12 pitch, a minimum of one sprinkler shall be located above the edge of the fuel-fired equipment protection area, on the upslope side of the equipment. (3) Freeze protection shall be provided in accordance with Sprinkler protection should be required for areas that contain fuel-fired equipment (source of ignition). The purpose of this PI is to provide minimum design requirements for protection of fuel-fired equipment. Sections (and proposed 6.6.7) require protection in spaces that contain fuel-fired equipment. However the base code does not provide criteria for protection of these spaces. One interpretation of this code section would indicate that the entire space would need to be provided with fire sprinklers. However, this is not seen as prudent, as it could lead to requiring sprinklers throughout an attic simply due to having a few pieces of fuel-fired equipment in a small portion of the attic. Therefore, this code section is proposed to simply indicate that a minimum of one sprinkler head be located above the fuel-fired equipment. Additional sprinkler heads may be required if there are multiple pieces of equipment, which would together form an area that is called fuel-fired equipment protection area and is simply an area with boundaries that contain all fuel-fired equipment within those boundaries. Where there is a slope to the roof, it is felt that the heat from fire will travel up the slope of the roof. Therefore, the proposal requires that in cases where the slope exceeds 4:12, then at least one of the sprinkler heads need to be located at the edge of the protection area on the upslope side, in order to ensure that a head activates.

A NFPA 13 requires a separate sprinkler system per floor in multi-story buildings meeting certain requirements. It should not be necessary to follow these rules where there are mixed occupancies and the use of NFPA 13 & NFPA 13R systems * In buildings with mixed occupancies and the non-residential occupancy is mercantile, it shall have a separate control valve. A Many mercantile spaces require modifications as tenants move in and out. The addition control requirement is to prevent the residential portion from being shut down during modifications. Since the committee has made it clear that differing sprinkler systems can exist in a building with residential occupancies, there needs to be some rules as how to arrange the control valves.

Attics that are intended for occupancy or storage shall comply with Section 7.1, where the attic is part of the dwelling unit, or Section 7.2, where the attic is outside of the dwelling unit. Sprinkler temperature ratings shall comply with Section Fuel Fired Equipment. Where fuel-fired equipment is installed in an attic that is not otherwise required to have sprinklers, at least one quick-response intermediate temperature sprinkler shall be installed above the equipment * Other Attics. Attics that are not required by Section to have sprinklers shall be permitted to have protection in accordance with one of the following. Sprinkler temperature ratings shall comply with Section Protection complying with NFPA Protection using sprinklers that are specifically listed to provide attic protection in residential occupancies using a discharge density of not less than 0.05 gpm/ft2 (2.04 mm/min) and a design area of not less than 4 sprinklers. A NFPA 13R does not require installation of sprinklers in attics that are not intended for occupancy or storage. However, model building codes sometimes require protection of attics in tall, combustibleframed residential occupancies that are otherwise allowed to follow NFPA 13R. Such protection is permitted to be provided by sprinklers or other means allowed by the model building code or NFPA 13, as specified for protection of combustible concealed spaces. Common methods of protection in lieu of sprinklers include filling the space with non-combustible insulation, using fire-retardant treated wood, or using non-combustible materials. Even though sprinklers are not mandatory for attic protection under NFPA 13R, NFPA 13R offers appropriate design requirements for cases where sprinklers are provided and sets design benchmarks that parallel what is permitted for garages. Renumber existing 7.4 as 7.5 Section and require sprinklers in attics that are intended for living or storage purposes and for attics that contain fuel-fired equipment, and it is helpful to provide guidance on attic protection in Chapter 7 to correlate. In addition, model building codes are adding requirements for some other attics to be protected with sprinklers or other acceptable means for protection of concealed spaces. It is important for NFPA 13R to provide guidance on protection of attics for these situations as well. The proposal parallels the design guidance for garages by offering an option to use not less than a 0.05 gpm/sqft density and not less than a 4 sprinkler design basis. However, the minimum density and minimum number of sprinklers would have to be determined based on testing and a listing for this specific hazard, as validated by a listing agency. The second design option is necessary to state in NFPA 13R to provide an alternative to the general provisions in Section 6.6.8, which would otherwise require compliance with NFPA 13 as the only basis for attic sprinkler protection.

Where a water tank is installed, the water tank shall be installed in accordance with NFPA * Domestic Demand. Domestic demand for the building being calculated shall be included as part of the overall system demand for systems with common domestic/fire mains where no provisions are made to prevent the domestic waterflow upon sprinkler system activation. 9.8 Penstocks, flumes, Rivers, or Lakes. Water supply connections from penstocks, flumes, rivers, lakes or reservoirs shall be arranged to avoid mud and sediment and shall be provided with approved double removable screens or approved strainers installed in an approved manner Non Fire Protection Connections. Sprinkler systems with non fire protection connections shall not be permitted. A The connection to city mains for fire protection is often subject to local regulation of metering and backflow prevention requirements. Where connections are made from public waterworks systems, such systems should be guarded against possible contamination as follows (see AWWA M14, Recommended Practice for Backflow Prevention and Cross Connection Control). A Preferred and acceptable water supply arrangements are shown in Figure A (a), Figure A (b), and Figure A (c). Where it is necessary to use a meter between the city water main and the sprinkler system supply, an acceptable arrangement as shown in Figure A (c) can be used. Under these circumstances, the flow characteristics of the meter are to be included in the hydraulic calculation of the system. Where a tank is used for both domestic and fire protection purposes, a low water alarm that actuates when the water level falls below 110 percent of the minimum quantity specified in Section 9.2 should be provided. A.9.3(1) Pumps that are owned and operated by thea public or private waterworks utility are not required to meet NFPA 20 because the waterworks industry standards for reliability and redundancy take care of concerns regarding reliability for fire fighting operations. If there is any concern over the Page 241 of 298

247 use of these non NFPA 20 pump installations, then the waterworks would not be considered reliable and would not be permitted as a water supply. An authority having jurisdiction has the authority to review a combined domestic/fire protection pump arrangement and determine whether or not the reliability and redundancy meets the intent of NFPA 20, even if the exact arrangement of equipment does not meet the rules of NFPA 20. INSERT FIGURES A.9.3(a), A.9.3(b), and A.9.3(c) and rename as A.9.5.1(a), A.9.5.1(b), and A.9.5.1(c) Private pumps taking suction from the waterworks system need to comply with NFPA20, even if they supply both fire protection and domestic water uses, unless they comply with the same waterworks industry standards for reliability and redundancy as the pumps owned by a waterworks utility. A.9.3(4) Pumps taking water from a stored source need to meet NFPA 20 requirements, even when they supply both fire protection and domestic water uses, unless they comply with waterworks industry standards for reliability and redundancy. An authority having jurisdiction has the authority to review a combined domestic/fire protection pump arrangement and determine whether or not the reliability and redundancy meets the intent of NFPA 20, even if the exact arrangement of equipment does not meet the rules of NFPA 20. A.9.6 Table A.9.6(a) and Table A.9.6(b) can be used to determine a domestic design demand. Using Table A.9.6(a), the total number of water supply fixture units downstream of any point in the piping serving both sprinkler and domestic needs is determined. Using Table A.9.6(b), the appropriate total flow allowance is determined and added to the sprinkler demand at the total pressure required for the sprinkler system at that point. Page 242 of 298

249 4 of 139 6/30/2016 1:23 PM Public Input No. 35-NFPA 13R-2016 [ New Section after 9.3 ] The flow and pressure of a public water supply shall be determined from waterflow test data or other approved method Water supply fluctuations must be addressed in the design of sprinkler systems, as required by the Authority Having Jurisdiction Safety factors must be addressed in the design of sprinkler systems, as required by the Authority Having Jurisdiction. The intent of this proposal is to recognize the need for evaluation of water supply fluctuations and safety factors in system design. The International Codes now specifically require that water supply fluctuations be addressed in sprinkler system design as follows (from 2015 IFC, Section ): "For connections to public waterworks systems, the water supply test used for design of fire protection systems shall be adjusted to account for seasonal and daily pressure fluctuations based on information from the water supply authority and as approved by the fire code official." Additionally, NFPA 14 (2016 edition) now states: " Daily and seasonal flow and pressure fluctuation data shall be provided by the water purveyor, and the fire protection design must account for both high and low variations Where these data are not available, design shall be based on the available water flow data." This proposal is simply an intent to recognize the need for and importance of water supply fluctuation to be evaluated, as well as to recognize that many jurisdictions require safety factors in the design of sprinkler systems. There is an additional similar proposal to NFPA 13 in this regard to move the requirement to address pressure fluctuations back into the body of that standard, rather than just in the Appendix.

P R = The residual pressure measured during the waterflow test while the flow Q R was discharging from the water supply. P S = The static pressure measured during the waterflow test. Q R = The flow discharging from the water supply when P R was measured. P L = The expected low static pressure at the location of the test results accounting for daily and seasonal fluctuations (not extreme conditions) obtained from the water utility. Where the water authority does not provide P L, see Where the water authority does not provide a value for P L, the value of P L shall be calculated from the following formula: P L = P S 10 psi Additional Proposed Changes File Name Description Approved Safety_Margin_Proposal- NFPA_13R.docx This provides the formula that I can't get into Terra View and shows the effect of the annex text as well. There needs to be a reasonable adjustment to water supply data in order to accommodate changes due to daily and seasonal fluctuations. The fact that this is currently not a requirement allows the design of fire protection systems that are known by the designer to have an ineffective water supply almost immediately after installation. This proposal takes care of the traditional arguments against a mandated safety margin by creating a standardized method of calculating that safety margin; however, this standardized method is only used if there is no information regarding the water utility. So, those situations where the fluctuations in the water delivery are known at a particular location, then these take priority. Spelling out the fact that NFPA 13R is not expecting unusual circumstances like water main breaks and 100 year droughts should help alleviate liability concerns on the part of the water utility, which should lead to a more open dialog between the fire protection professional and the water utility representative. The reality is that extreme conditions like 100 year droughts and water main breaks are better handled by the Impairment Procedures of NFPA 25. One of the concerns about this proposal last cycle was that there was no way to account for the situation where the water utility brings more pumps on line as the flow demand increases. These situations produce a water Page 245 of 298

251 Insert new sections as follows: Water Supply Adjustment Proposals Put Together 9.4 Where a waterflow test was conducted to determine the strength of a water supply, the volume and pressure available for use for a fire protection system shall be determined from either or * Knowledge of the water supply and engineering judgment taking into account reasonable daily and seasonal fluctuations not extreme conditions * Use of the following formula: P Q Q R 1.85 PR PS PL P = The pressure available from the water supply to use for a fire protection system that will be calculated for a given flow (Q) Q = The flow that will be used to calculate the available pressure from the water supply. PR = The residual pressure measured during the waterflow test while the flow QR was discharging from the water supply. PS = The static pressure measured during the waterflow test. QR = The flow discharging from the water supply when PR was measured. PL = The expected low static pressure at the location of the test results accounting for daily and seasonal fluctuations (not extreme conditions) obtained from the water utility. Where the water authority does not provide PL, see Where the water authority does not provide a value for PL, the value of PL shall be calculated from the following formula: PL = PS 10 psi A An adjustment to the waterflow test data to account for the following should be made, as appropriate: (1) Daily and seasonal fluctuations (2) Possible interruption by flood or ice conditions (3) Large simultaneous industrial use (4) Future demand on the water supply system (5) Other conditions that could affect the water supply Page 246 of 298

252 A The purpose of the adjustment is to take into account reasonable daily and seasonal variations in the water supply, which are easily predicted and tracked by a water utility. It is not the intent to use this section to account for unusual conditions such as 100 year droughts or water main breaks. These unusual conditions are handled through the Impairment Procedures of NFPA 25 and should not be considered when determining the ability of a water supply to meet the demand of a fire protection system under more normal circumstances. A Consider the following example. A waterflow test is conducted at a location where a city water main is going to be tapped for a new sprinkler system. During the test, the static pressure is measured at 70 psi, the residual pressure is measured at 50 psi while 1300 gpm was discharging from a nearby hydrant. The water utility is contacted and they indicate that a reasonable low static pressure accounting for typical daily and seasonal fluctuations in this area is 55 psi. The equation that describes the water supply available for a fire sprinkler system would be: P Q There are two ways to use this formula. One would be to assume two different values for Q, calculate P and then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling on or below the line on this graph would be acceptable in accordance with NFPA 13 to work with this water supply. In this case, the two easiest flows to pick for Q would be 0 and 1300 gpm. When Q = 0, P is simply 55 psi. When Q = 1300 gpm, P = 35 psi. These two points can be plotted on log 1.85 paper as shown in Figure A The second way to use this formula would be to calculate the fire protection system and determine the flow necessary to make the system work. Plug this flow into the formula above and see what the available pressure from the water supply will be at that flow. For example, if a sprinkler system connected to this water supply had a demand of 580 gpm, the available pressure from the water supply would be: P P = (-20)(0.225) + 55 P = 50.5 psi So, as long as the sprinkler system has a pressure demand less than or equal to 50.5 psi, it will work with this water supply.

NFPA 22 does not address storage tanks for smaller amounts of water required for an NFPA 13R system. NFPA 22 does not permit plastic tanks such as those often used in 13D applications. Due to the increase in retrofitted systems in adult care "houses", we have found section 9.5 creates an unreasonable cost increase on small businesses by not allowing plastic tanks to be installed. The AHJ should be afforded the opportunity to approve plastic tanks in lieu of larger, more expensive tanks with unnecessarily higher capacities.

Domestic For systems with common domestic/fire mains serving more than one dwelling unit, domestic demand for the building being calculated shall be included as part of the overall system demand for systems with common domestic/fire mains where no unless provisions are made to prevent the domestic waterflow upon sprinkler system activation. Four story townhouses have become a popular type of dwelling unit being constructed in many areas, and the International Building Code requires such structures to have a sprinkler system installed in accordance with NFPA 13R in order to have the fourth story. For the most part, these sprinkler systems are not that different from NFPA 13D systems, other than the number of sprinklers calculated. The issue that arises is that the sprinkler supply is usually from a common supply line feeding the domestic water, and most public water authorities require the sprinkler connection to be on the 'downstream' side of the water meter. Even with a 1-inch water meter (which is the largest size that most water authorities will allow on a single-family dwelling), the domestic demand added to the four-sprinkler flow usually results in a total volume beyond the listed rating of the water meter. Historically, NFPA 13D has not required domestic water demand to be included in the sprinkler demand when the common domestic/fire main serves a single dwelling unit. The same philosophy should apply in the scenario of a four-story single-family dwelling. Submitter Full Name: Ivan Humberson Organization: City Of Gaithersburg, Md.

It becomes extremely expensive and over-burdensome for each dwelling unit to have six spare sprinklers. From almost all aspects other than sprinkler hydraulic design, these dwellings are practically identical to homes protected by sprinkler systems designed by NFPA 13D, which requires no spare sprinklers. By minimizing the required number of spare sprinklers required for four-story single-family dwellings, the cost to the home buyers is thereby reduced.

271 13 of 139 6/30/2016 1:23 PM NFPA 13R is appropriate for use as an alternative to NFPA 13 only in those residential occupancies, as defined in this standard, up to and including four aboveground stories in height. It should be noted that model building codes contain special allowances for "pedestal" or "podium" style buildings, which permit the story height for structures above the pedestal to be measured from the top surface of the pedestal, rather than from grade plane, and it is the intent of NFPA 13R to follow this model building code method for determining the number of stories. Accordingly, it is possible for a 4-story residential structure to be within the scope of NFPA 13R even when that structure is constructed on top of a 1-story pedestal. However, where this is allowed, model building codes will require the pedestal portion to be constructed using Type I construction, and limited to buildings that are the pedestal portion will be required to be protected by an NFPA 13 compliant sprinkler system. Regardless of whether a building does or does not involve a pedestal, NFPA 13R systems are always limited to structures that do not exceed 60 ft (18 m) or less in height above grade plane, which is. Note that model building codes do not allow building height to be measured from the top of a pedestal. That allowance only applies to determiming the number of stories. The 60-foot overall height limit is consistent with limits established by model building codes for buildings of Type V construction. The height of a building structure above grade plane is determined by model building codes, which base the height on the average height of the highest roof surface above grade plane. For further information on the building height story limits, see model building codes. Buildings that contain multiple occupancies (either separated or non-separated), accessory occupancies or incidental uses are often subject to special rules that may restrict the use of NFPA 13R. Refer to the adopted building code to determine whether such restrictions are applicable. The criteria in this standard are based on full-scale fire tests of rooms containing typical furnishings found in residential living rooms, kitchens, and bedrooms. The furnishings were arranged as typically found in dwelling units in a manner similar to that shown in Figure A.1.1(a), Figure A.1.1(b), and Figure A.1.1(c). Sixty full-scale fire tests were conducted in a two-story dwelling in Los Angeles, California, and 16 tests were conducted in a 14 ft (4.3 m) wide mobile home in Charlotte, North Carolina. Sprinkler systems designed and installed according to this standard are expected to prevent flashover within the compartment of origin where sprinklers are installed in the compartment. A sprinkler system designed and installed according to this standard cannot, however, be expected to completely control a fire involving fuel loads that are significantly higher than average for dwelling units [10 lb/ft 2 (49 kg/m 2 )], configurations of fuels other than those with typical residential occupancies, or conditions where the interior finish has an unusually high flame spread index (greater than 225). To be effective, sprinkler systems installed in accordance with this standard need to open the sprinklers closest to the fire before the fire exceeds the ability of the sprinkler discharge to extinguish or control the fire. Conditions that allow the fire to grow beyond that point before sprinkler activation or that interfere with the quality of water distribution can produce conditions beyond the capabilities of the sprinkler system described in this standard. Unusually high ceilings or ceiling configurations that tend to divert the rising hot gases from sprinkler locations or change the sprinkler discharge pattern from its standard pattern can produce fire conditions that cannot be extinguished or controlled by the systems described in this standard. NFPA 13R references NFPA 13 in many aspects (hanging and bracing, design densities and spacing outside of dwelling unit, painting and finish of sprinklers, welding, etc.). If this standard does not specifically address a situation, NFPA 13 is a good resource that can be utilized by the installer and the authority having jurisdiction for a solution. It is not the intent of this standard to require compliance with NFPA 13 when NFPA 13R is silent on a subject. Only AHJ approval should be required. Figure A.1.1(a) Bedroom. Page 266 of 298

277 19 of 139 6/30/2016 1:23 PM Various levels of sprinkler protection are available to provide life safety and property protection. This standard is designed to provide a high, but not absolute, level of both life safety and a lesser level of property protection. Greater protection to both life and property could, but to a lesser degree than would be achieved by sprinklering all areas in accordance with using NFPA 13, which permits the use of residential sprinklers in residential areas. This standard recommends, but does not require, sprinklering of all areas in the building; it permits sprinklers to be omitted in certain areas. These areas have been proved by NFPA statistics to be those where the incidence of life loss from fires in residential occupancies is low. Such an approach provides a reasonable degree of fire safety. (See Table A.1.2 for deaths and injuries in multifamily residential buildings.) It should be recognized that the omission of sprinklers from certain areas could result in the development of untenable conditions in adjacent spaces. Where evacuation times could be delayed, additional sprinkler protection and other fire protection features, such as detection and compartmentation, could be necessary.

Source: NFIRS and NFPA survey. Clarification of intent. NFPA 13R is both a life-safety and property-protection standard. It is recognized for property protection by model building codes, which grant construction incentives to buildings protected by NFPA 13R systems, and sprinklers required for protection of balconies and garages are primarily provided for property protection. Certainly, NFPA 13 provides an increased level of protection for both life-safety and property protection, and the proposed revision makes this clear.

Some residential sprinklers have been investigated and listed for use under specific ceiling configurations such as a horizontal beamed ceiling. The performance of residential sprinklers under flat, smooth, horizontal ceilings has been well documented throughout the life of NFPA 13R. Prior to 2010, several manufacturers of residential sprinklers had performed testing and received listings for residential sprinklers under certain slopes and in certain beam conditions. In 2010, the Fire Protection Research Foundation (FPRF) conducted a research project consisting of 76 FDS simulations and 12 full-scale fire tests. The results have been used to develop system design criteria in a generic manner in order to simplify the use of residential sprinklers. Some residential sprinkler listings still exist for situations beyond the scope of the generic design. See the FPRF report, Analysis of the Performance of Residential Sprinkler Systems with Sloped or Sloped and Beamed Ceilings, dated July 2010 for more information. For examples of selecting a compartment for consideration, see Figure A (a) and Figure A (b), which show examples of design configurations for compartments based on the presence of lintels to stop the flow of heat.

It is not the intent to use this section to account for unusual conditions such as 100 year droughts or water main breaks. These unusual conditions are handled through the Impairment Procedures of NFPA 25 and should not be considered when determining the ability of a water supply to meet the demand of a fire protection system under more normal circumstances. A Consider the following example. A waterflow test is conducted at a location where a city water main is going to be tapped for a new sprinkler system. During the test, the static pressure is measured at 70 psi, the residual pressure is measured at 50 psi while 1300 gpm was discharging from a nearby hydrant. The water utility is contacted and they indicate that a reasonable low static pressure accounting for typical daily and seasonal fluctuations in this area is 55 psi. The equation that describes the water supply available for a fire sprinkler system would be: There are two ways to use this formula. One would be to assume two different values for Q, calculate P and then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling on or below the line on this graph would be acceptable in accordance with NFPA 13 to work with this water supply. In this case, the two easiest flows to pick for Q would be 0 and 1300 gpm. When Q = 0, P is simply 55 psi. When Q = 1300 gpm, P = 35 psi. These two points can be plotted on log 1.85 paper as shown in Figure A The second way to use this formula would be to calculate the fire protection system and determine the flow necessary to make the system work. Plug this flow into the formula above and see what the available pressure from the water supply will be at that flow. For example, if a sprinkler system connected to this water supply had a demand of 580 gpm, the available pressure from the water supply would be: P = (-20)(0.225) 55 P = 50.5 psi So, as long as the sprinkler system has a pressure demand less than or equal to 50.5 psi, it will work with this water supply.
