1 Page 1 of 198 Public Input No. 88-NFPA [ New Section after ] Add New Defination Multiple Stage Multiple Port Pump. A single driver pump with multiple impellers operating in series where the discharge from each impeller except the last impeller is the suction for the next impeller, and a discharge port is provided after each impeller. NFPA 20 does not currently address multiple stage multiple port fire pumps Related Public Inputs for This Document Related Input Public Input No. 83-NFPA [New Section after 6.2.2] Relationship Submitter Full Name: Gayle Pennel Organization: Aon Fire Protection Engineerin Submittal Date: Mon Jun 17 16:07:21 EDT 2013 I, Gayle Pennel, hereby irrevocably grant and assign to the National Fire Protection Association (NFPA) all and full rights in copyright in this Public Input (including both the Proposed Change and the Statement of Problem and Substantiation).

Drawings ( as-built drawing ) that is submitted as the final record of documentation for the project. document the location of all devices, appliances, wiring sequences, wiring methods, and connections of the components of the system as installed [72:2016] Paragraph 14.3 refers to record drawings so the definition has been revised to be plural. It would be extremely rare that the design drawings could serve as the record drawings. The record drawings should indicate the as build (installed) condition. In searching for a better definition, it was noted that NFPA 72 already has a definition so it is proposed to extract the definition from NFPA 72. While there may be some text not exactly related to a fire pump installation, the definition still seems to be applicable. Submitter Full Name: William Koffel Organization: Koffel Associates, Inc.

7 Page 6 of 198 The intent is to clean up the requirements so that they are applicable to fire pump installations. The following changes were made: 1. The weight of the suction piping was eliminated because that is not important. How many pounds of suction pipe are present is not an aspect of fire pump installations that should be subjected to plan review. 2. The "valves, regulators, meters, and valve pits" were moved to their own line with "if present" added to them because they are not always included in a fire pump installation and they should not be limited to suction piping. The AHJ should get this information about valves regarding the discharge valves as well. 3. The "valve indicators" was removed because the type of valve will be included with the description and size of the valve. We should not also have to described the size of the stem coming out of the valve to indicate that it is open. 4. The water supply information in part (8) (except for item "I" which was dealt with separately) only applies to flow test information, so this portion of the list was clarified to show that it only applies to those situations where a flow test was run. 5. The "riser reference point" was changed to "elevation reference point" because a fire pump installation does not have a riser. 6. Item "I" was moved to its own item in the list because it does not pertain to a flow test. Flow and size information was added because this is an important point for items like tanks. 7. Voltage and fuel system requirements were separated to make them independent. 8. The term "if provided" was added to the jockey pump information because they are not always provided and you should not have to provide information on a jockey pump that is not present. The whole section should look like the following (a legislative version will be provided as an uploaded file because the system messed it up completely): Plans shall be drawn to an indicated scale, on sheets of uniform size, and shall indicate, as a minimum, the items from the following list that pertain to the design of the system: 1. Name of owner and occupant 2. Location, including street address 3. Point of compass 4. Name and address of installing contractor 5. Pump make and model number 6. Pump rating psi rpm 7. Suction main size, length, location, type of material, and point of connection to water supply as well as depth to top of pipe if below grade 8.

10 Page 9 of 198 Public Input No. 32-NFPA [ Section No ] Where a water flow test is used to determine the adequacy of the attached water supply, the test shall have been completed not more than 12 months prior to the submission of working plans and shall represent the highest peak demand on the attached water supply, unless otherwise permitted by the authority having jurisdiction. Currently there is no guidance or requirements regarding the performance of the attached water supply. Fire pump installers can perform fire pump testing when the water supply is under its least demand. There are instances where the water supply may be inadequate because the demand generated by other users. The fire pump test would fail; however, the pump test could be performed when demand for water is significantly less resulting in an adequate supply of water. The purpose of the pump is to supply water for the purposes of fire protection 24/7, 365 days per year, and it should be tested when the water demand is the greatest. This would result in a more accurate performance of the fire protection system and provide more accurate information for fire department pre-planning efforts where the water system may under perform. In the event that the water supply is deemed inadequate the provisions of and would apply.

16 Page 15 of 198 Public Input No. 125-NFPA [ New Section after ] Full flow of cooling water to the pump during churn in variable speed pressure limiting controlled fire pumps Where an electric variable speed pressure limiting controller is installed, the automatic relief valve shall be bypassed by a normally-closed, electric solenoid operated valve, permitting full flow of cooling water to the pump when the variable speed pressure limiting controller is running regardless of the discharge output of the pump. Energy to operate the solenoid valve shall be provided by the variable speed pressure limiting controller when operating in variable speed mode only. When the pressure set point is satisfied during churn, the variable speed drive runs at a minimum speed which is often set at 50% of rated motor full-speed. Not enough pressure is developed at this minimum speed to provide adequate water flow for cooling the pump. This is a concern since the pump can be running in churn for a period of time during a weekly or monthly test for example. Outside of the variable speed drive, the problem doesn't exist since the motor is operating at full-speed during churn and is developing adequate pressure for flowing cooling water, unless of course, the relief valve isn't properly set.

20 Page 19 of 198 Public Input No. 134-NFPA [ Section No ] Fire pump rooms not directly accessible from the outside shall be accessible through an enclosed passageway from an enclosed stairway or exterior exit, which is not part of a required means of egress. Access to a fire pump room should not be allowed to be from a protected exit enclosure. Protected exit enclosures are very important to the means of egress and should not be utilized for this type of equipment access. Any problems associated with equipment failure could jeopardize the integrity of the means of egress, as protected exit enclosures are dedicated egress paths. It appears that the allowance in this section of NFPA 20 conflicts with NFPA 5000, section , and also the IBC. These documents do not allow such openings into protected exit enclosures. NFPA 5000, section * states: Openings in exit enclosures shall be limited to doors from normally occupied spaces and corridors and for egress from the enclosure, unless such openings are in exit passageways in mall buildings, as provided in NFPA 5000, section A states: Means of egress from the level of exit discharge is permitted to pass through an exit stair enclosure or exit passageway serving other floors. Doors for convenience purposes and unrelated to egress also are permitted to provide access to and from exit stair enclosures and exit passageways, provided that such doors are from corridors or normally occupied spaces. It is also the intent of this provision to prohibit exit enclosure windows, other than approved vision panels in doors, that are not mounted in an exterior wall. This revision would require a dedicated and protected access to the fire pump room, if there is no direct access from outside. This will ensure that during a fire, the fire department has good access to the fire pump room without the risk of compromising the protected exit enclosure. If the Technical Committee does not agree with this change, then consideration should be given to adding an exception for fire pump room access in NFPA Submitter Full Name: Jim Muir Organization: Building Safety Division, Clark County, Washington Affilliation: NFPA Building Code Development Committee (BCDC) Submittal Date: Mon Jul 08 12:44:22 EDT 2013

22 Page 21 of 198 Public Input No. 30-NFPA [ Section No ] Fire pump rooms not directly accessible from the outside shall be accessible through an enclosed passageway from an enclosed stairway or exterior exit passageway.

23 Page 22 of 198 Public Input No. 64-NFPA [ New Section after ] The minimum average horizontal illumination provided by normal lighting sources in the separate building or room housing the fire pump equipment shall be 32.3 lux (3.0 ft-candles) measured at the floor level, unless otherwise specified by a requirement recognized by the authority having jurisdiction. The level of illumination required by NFPA 101 for emergency light is an average of 1 ftcandle and, at any point, not less than 0.1 ft-candle. While adequate for egress purposes, the level of illumination is not adequate for a person to work in a fire pump room should normal power be lost. The level of illumination recommended in this Public Input is consistent with a Level 1 EPS room (per NFPA 110). The Committee might also want to consider requirement battery-operated emergency light units consistent with the requirements in NFPA 110. The Committee may also want to give consideration to the duration of the emergency lighting system. NFPA 101 would require a minimum of 90 minutes and would the lighting level to degrade from the performance stated above during that time period. Whereas the water supply duration and operation of the fire pump may be in excess of 90 minutes, NFPA 20 may want to require emergency lighting for a longer period of time.

When installed, the pressure relief valve shall be set to operate at a pressure at or below the pressure rating of the system components adjusted for elevation. Under current requirements pressure relief valves are installed to protect against the failure of a variable speed pump or diesel engine overspeed. It is preferrable to subject system components to a limited pressure excess rather than installing a pressure relief valve that introduces another failure mode. Currently systems may be hydrostatically tested to 50 psi over there rated pressure and pressure relief valves are allowed by the testing standards to exceed the set pressure by 25%. 125% of rated pressure is well below the component safety factor and is a reasonable overpressurization to avoid pressure relief valves.

The relief valve size shall be determined by one of the methods specified in or * The relief valve shall be permitted to be sized hydraulically to discharge sufficient the minimum size that will flow sufficient water to prevent the pump discharge pressure, adjusted for elevation, from exceeding the pressure rating of the system components If the relief valve is not sized hydraulically, the relief valve size shall not be less than that given in Section (See also and A for conditions that affect size.) Failure of an oversized pressure relief valve will divert all or a substantial amount of water from the fire protection system.

Additional Proposed Changes File Name 20_Yacine.pdf Description Approved Cover sheet We are operating oil & gas onshore based production and processing facilities. We have a firewater system, including fire water main covering different installations and equipments, a firewater tank, and three firewater pumps two electric pumps and one diesel with two jockey pumps for pressure maintenance. The firewater system in its current status is virtually designed in accordance to NFPA 20. First, with regard to NFPA 20, we have no means to close the pressure relief valve in order to conduct fire pump performance test as required by NFPA 25, In fact our relief valves don't have the option to be maintained closed in all flow conditions. Moreover, we cannot see the difference between a closed relief valve and a closed relief valve discharge. So we believe that installing shutoff valves in the discharge side of the relief valves will allow as accomplishing fire pump performance test in accordance to NFPA 20 and NFPA 25. Second, our relief valves discharge lines off of the three main pumps and the two jockey pumps are connected to a common discharge header which goes back to the bottom the storage tank (the supply source) which is not in accordance to NFPA 20, Consequently we are not able to inspect or repair the pressure relief valves without isolating and shutting downt he whole firewater system for an extended period which in turn will compromise the safety of our installations. While it is not cost effective to run discharge piping returning water back tot he storage tank independently from each pump's pressure relief valve, installing shutoff valves in the discharge side of the pressure relief valves will permit us to inspect and maintain them without the need to isolate and shutdown the whole firewater system. We understand that the firewater system (our more important emergency response equipment) should be design engineered in such a way to prevent human errors (such as forgetting the shutoff valve in the closed position) from compromising its integrity nevertheless it is worthy noting that we are installing shutoff valves in the discharge of relief devices within other process equipments involving higher pressures with more hazardous fluids and it is permitted according to ASME Pressure Vessel Code, Section VIII, Appendix M, M-6 Stop Valves on the Discharge Side of a Pressure Relieving Device, and API RP 520, Part II, Section 4 Isolation (Stop) Valves in Pressure Relief Piping while, of course managing valves positions by procedures. So, why are we not allowed, as per NFPA 20, to do this within FW pumps?

50 Page 48 of 198 Public Input No. 26-NFPA [ New Section after ] TITLE OF NEW CONTENT Fire pumps that operate in series that are not located in the same room shall comply with the following. 1) No more that two pumps shall operate in series. 2) Each pump shall be arranged so that it can be manually stopped or started from the other pump room. 3) The suction and discharge pressures from each pump shall be displayed in the other pump room. 4) All trouble signals from each pump shall be displayed in the other pump room. Communicating between fire pump rooms is difficult. Operating pumps simultaneously in separate rooms requires one operator to know the conditions at both pumps. Low suction pressure at the remote pump should be responded to immediately to prevent damage to the fire pump. Remote operation capability allows a fire to act when possible, or warn firefighters that are depending on the water supply of abnormal pumping conditions.

Retrofit of backflow preventers is common on fire pump systems. When the backflow device is installed on the suction side, we need to make sure that the backflow device does not impair the fire pump and that the backflow device will not impair the fire protection system. When the backflow device is installed on the discharge side, we need to make sure that it does not impair the fire protection system. These same requriements are in other NFPA standards, but the scope of NFPA 20 keeps the suction and discharge piping out of the scope of other standards, so techncially, they don't apply. Therefore, these requirements need to be included in NFPA 20 so that they apply whenever a backflow device is retrofitted on suction or discharge piping.

72 Page 70 of 198 Public Input No. 103-NFPA [ Section No ] * Relief Valves for Foam Concentrate Pumps. For foam concentrate pumps, safety relief valves shall be piped to return the valve discharge to the concentrate supply tank. Section is inconsistent in its requirements with Section for the same type of pump and is also inconsistent with what is required by and illustrated in NFPA 11. Sections and both detail safety relief valve requirements for positive displacement pumps but makes allowance for piping of the relief valve discharge to the suction side of the pump. NFPA 11 states in section that positive displacement pumps shall be provided with a means of pressure relief from the discharge to the supply side of the circuit. No location on the supply side of the circuit is specifically prohibited for the relief valve discharge to be piped to. Figures A and A (a) on page of the 2010 Edition of NFPA 11 both illustrate a positive displacement foam pump with the safety relief valve discharge piped to the pump suction, in direct conflict with Section of NFPA 20. Positive displacement pumps for use with foam and watermist have no substantial differences and, frequently, the same makes and models of pumps are used for both applications. There is no sound technical reason for safety relief valves for positive displacement pumps used with foam concentrate to have different piping requirements than those used for watermist applications.

Additional Proposed Changes File Name nfpapublicinputform_kovacik2.docx Description Approved Cover Sheet The term Listed fire pump power transfer switch assembly was added to Appendix A of the 2013 Edition of NFPA 20, but not referred to in the body of the standard. Reference Figure A.10.8, Arrangement II. The intent was to recognize the use of a fire pump power transfer switch assembly which could include an isolating switch and overcurrent protection for the transfer switch in the same enclosure as the transfer switch. As a fire pump transfer switch is required to be located in the pump room, the overcurrent protection and isolating switch, when provided as part of the transfer switch assembly, would not be remote from the fire pump controller. When the subject of a transfer switch assembly was discussed during the last code cycle, it was anticipated that the overcurrent protection and isolating switch, when provided as part of the transfer switch assembly would not be the one disconnecting means and associated overcurrent protection device permitted by In order to allow an additional disconnecting means and associated overcurrent protection device to be remote from the pump room in such installations, the added text is necessary.

82 Page 80 of 198 Additional Proposed Changes File Name Description Approved docx Cover Sheet Tables_ _a_and_b_.doc Tables (a) & (b) PI 157 This proposal is summarized as follows; 1. Table is being revised to correct values to represent current motor design and construction. 2. Table is being revised to add motors with three phase horsepower ratings not currently in the table. 3. Table is being revised and split into two tables, Tables (a) and (b). Table (a) will be the existing Table (revised per items 1 and 2 above) and cover three phase motors. Table (b) will be a new table covering single phase motors which are not currently covered by NFPA Clause is being revised to specify and differentiate the NEMA motor designs for three and single phase motors. 5. The source documents for values inserted in the tables are UL for three phase motors and NEMA MG-1 for single phase motors. The following is background information relating to these changes. 1. There are no NEMA Design B standards for single-phase motors. UL does not cover single phase motors. 2. MG1 has tables which lists the maximum limit on locked rotor currents for single phase motors. There are tables for small and medium motors. For the Design N (small) and Design L (medium) types the limit on LRA at 230 volts is NOT one-half of that at 115 volts. 3. The values of locked rotor amps given in the tables in MG1 standards are upper limits. 4. Design B performance standards for 3 phase medium motors in NEMA MG1 begin at a minimum rating of 1/2 hp. However, that is 1/2 hp at 900 RPM synchronous speed (8 poles) and slower speeds at 60 Hz. There are no NEMA Design B 1/2 hp motors in 2, 4, or 6 poles. Similarly, the Design B standard applies to 3/4 hp and higher at 1200 RPM (6 pole) and slower speeds (higher number of poles) 1 Hp and higher at 1800 RPM (4 poles) and slower speeds 1-1/2 Hp and higher at 3600 RPM (2 pole) and slower speeds. If a fire pump application requires the use of a 2, 4, or 6 pole polyphase motor rated 1/2 hp, it cannot be a NEMA Design B motor since such a motor does not exist. 5. NFPA 20, Table Horsepower and Locked Rotor Current Motor Designation for NEMA Design B Motors has errors for certain locked rotor amps and locked rotor code letters. UL has Tables with the correct values and should be used as a guide for revising Table NFPA 20, Table should be revised to add hp ratings below 5 hp. The lower limit should be 1 hp which is the smallest 3 phase NEMA Design B motor. 7. A separate table should be added to NFPA 20 for single phase motors. The range of horsepower ratings for the table could be 1/6 to 10 hp as there are published values of fullload currents for motors in this range. NEMA Design N single phase small motors exist only for 1/6 through 1 hp in 2 poles, 1/8 through 3/4 hp in 4 poles, and 1/8 through 1/2 hp in 6 poles. The upper rating in the range corresponds to the upper limit on hp for small motors. NEMA Design L single phase medium motors exist only for 1-1/2 through 10 hp in 2 poles, 1 through 10 hp in 4 poles, and 3/4 through 3 hp in 6 poles. It should be noted that for the Design N (small) and L (medium) types the limit on LRA at 230 volts is NOT onehalf of the LRA at 115 volts.

90 Page 86 of 198 Public Input No. 130-NFPA [ Section No ] Where the raceway (conduit) between the controller and motor is not capable of conducting ground fault current sufficient to trip the circuit breaker when a ground fault occurs, a separate equipment grounding conductor shall be installed between the controller and motor. Additional Proposed Changes File Name nfpapublicinputform_kovacik1.docx Description Approved Cover Sheet Clause was added to NFPA 2013 at the Comment stage of the process. Subsequently, I submitted a proposal for the 2014 NEC to include this same requirement in Article 695 which covers electrical installation requirements for fire pumps. At the ROP meeting, Code Panel 13 decided this requirement was not enforceable since there is no way for an AHJ to determine when a raceway (conduit) between the controller and motor is not capable of conducting ground fault current sufficient to trip the circuit breaker when a ground fault occurs. The Panel modified the proposal to require an equipment grounding conductor in all installations between the controller and motor (redundant grounding). The panel substantiated that if conducting ground fault current may be a concern with any installation, mandating the use of an equipment grounding conductor will remove that concern. At the ROC meeting, the Panel reversed its position and decided there is insufficient substantiation to require redundant grounding and decided to make no changes to Article 695 for the 2014 NEC. Based on the actions of Code Panel 13, it is proposed to delete Further to this subject, it is questionable whether this requirement belongs in NFPA 20 as NEC Article 695 has responsibility for electrical installation requirements for fire pumps.

(1)* For all pressure transducers relating to fire pump operation: Electronic pressure reading exceeding a preset high pressure value (2)* For a transducer in the automatic start pressure sensing line: minimum electronic pressure reading that fails to fall below a preset automatic start low value during automatic pump startup. (3)* For all pressure transducers relating to fire pump operation: Electronic pressure reading below a preset low value at any time except during an automatic startup. (4)* Any tine the transducer output is less than 10% of rated span below its rated zero pressure output. (5)* Any time is more than 10% of it's rated span above its rated full scale output. (6)* For a variable speed motor driven fire pump controller: any time the output from the variable speed control transducer differs from the output of the start/stop transducer by more than 5% of rated transducer span. (7)* For controllers equipped with weekly test start, when the pressure output is more than 5% of rated range above the rated zero output When one of the conditions monitered in occurs, the controller shall either activate a visual and silenceable audible alarm and activate contacts for a remote alarm, or start the pump. Failure of the pressure actuating mechanism can cause failure of the entire fire protection system. The recent transducer recall revealed the potential for failure. Although the recall may have addressed the immediate problem, the potential for future failures remains and can be addressed. Mercoid switches do not have any supervisorable mechanism to verify failures prior to testing. Tranducers are continously interacting with the controller and can be supervised.

Leavitt, Telgian Corporation Revise text to read as follows: Where environmental or fuel quality conditions result in degradation of the fuel while stored in the supply tank, from items such as water, micro-organisms and particulates, or destabilization, a listed active fuel maintenance system shall be installed to maintain fuel quality. Active fuel maintenance system shall be quipped with a visible indicator to indicate when the system is in need of maintenance. Active fuel maintenance system shall be quipped with contact closure for connect to the controller (ref. par ) to indicate when the system is in need of maintenance. When required the listed active fuel maintenance systems shall be permanently connected to the fuel tank as follows: (1) All connections made directly to the tank ((this language is from current par. A )) (2) The supply from the tank to the maintenance system shall be connected to the bottom of the fuel storage tank. (3) The return from the maintenance system to the fuel storage tank shall be installed as directed by the fuel maintenance system manufacturer. (4) No connections are interconnected with the engine or its fuel supply and return piping in any way. ((This language is from current par. A )) (5) No valves or other devices are added to the engine or its fuel supply and fuel return in any way. ((This language is from current par. A )) Commercial distillate fuel oils used in modern diesel engines are subject to various detrimental effects from storage. The origin of the crude oil, refinement processing techniques, time of year, and geographical consumption location all influence the determination of fuel blend formulas. Sulfur, naturally occurring gums, waxes, soluble metallic soaps, water, dirt, blends and temperature all contribute to the degradation of the fuel as it is handled and stored. These effects begin at the time of fuel refinement and continue until consumption. Proper fuel storage is critical for engine operation, efficiency, and longevity. Storage tanks should be kept water-free. Water contributes to steel tank corrosion and the development of microbiological growth where fuel and water interface. This and the metals of the system provide elements that can react with fuel to form certain gels or organic acids, resulting in clogging of filters and system corrosion. Scheduled fuel maintenance helps to reduce fuel degradation. Fuel maintenance filtration can remove contaminants and water and maintain conditions to provide reliability and efficiency for standby fire pump engines. Fuel maintenance and testing should begin the day of installation and first fill. In addition to an active fuel maintenance system a fuel stabilizer or other additives may be necessary to insure quality fuel for engine operation. Consult your active fuel maintenance system supplier or fuel supplier for guidance regarding fuel additives and maintenance requirements for long term storage. Low fuel level. Fuel supply trouble. Signal at two-thirds tank capacity, or when active fuel maintenance system needs maintenance. The characteristics of diesel fuel are changing and proper storage is becoming extremely important to insure reliable operation of engines. Even when the proper fuel has been purchased and put into the fuel storage tank long term reliability can not be assumed. For reasons as explained in the proposed annex text and governmental mandated addition of various blends of bio-fuel, diesel fuel is requiring additional attention to insure reliable use in diesel engines for stand-by service. Revise text to read as follows: Where environmental or fuel quality conditions result in degradation of the fuel while stored in the supply tank from items such as water, micro-organisms and particulates, or destabilization, A listed active fuel maintenance system shall be installed to maintain fuel quality with all fuel storage tanks.

154 Page 146 of 198 Public Input No. 23-NFPA [ New Section after ] TITLE OF NEW CONTENT When an electronic pressure sensor is used to control fire pump operation, the fire pump controller shall monitor for and provide a signal for the following electronic pressure sensor conditions. (1)* For all pressure transducers relating to fire pump operation: Electronic pressure reading exceeding a preset high pressure value (2)* For a transducer in the automatic start pressure sensing line: minimum electronic pressure reading that fails to fall below a preset automatic start low value during automatic pump startup. (3)* For all pressure transducers relating to fire pump operation: Electronic pressure reading below a preset low value at any time except during an automatic startup. (4)* Any tine the transducer output is less than 10% of rated span below its rated zero pressure output. (5)* Any time is more than 10% of it's rated span above its rated full scale output. (6)* For a variable speed motor driven fire pump controller: any time the output from the variable speed control transducer differs from the output of the start/stop transducer by more than 5% of rated transducer span. (7)* For controllers equipped with weekly test start, when the pressure output is more than 5% of rated range above the rated zero output When one of the conditions monitered in occurs, the controller shall either activate a visual and silenceable audible alarm and activate contacts for a remote alarm, or start the pump. The recent recall of Transducers clearly identifies a problem for failure that can be monitered by current technology. While the recall addressed the immediate problem, there is a likelihood of similar issues occurring in future problems. Mercoid switches do not have a mechanism outside of actual testing to identify failures, Transducers communicate continuously with the controller and can and should be monitored for abnormal conditions that may occur outside of testing.

175 Page 167 of 198 Public Input No. 52-NFPA [ Section No. A.4.12 ] NOTE: This proposal appeared as Comment (Log #269) which was held from the A12 ROC on Proposal A.4.12 Special consideration needs to be given to fire pump installations installed belowgrade. Light, heat, drainage, and ventilation are several of the variables that need to be addressed. The vertical elevation of both the fire pump and the controller should be coordinated to ensure that both will not be flooded. Some locations or installations might not require a pump house. Where a pump room or pump house is required, it should be of ample size and located to permit short and properly arranged piping. The suction piping should receive first consideration. The pump house should preferably be a detached building of noncombustible construction. A one-story pump room with a combustible roof, either detached or well cut off from an adjoining one-story building, is acceptable if sprinklered. Where a detached building is not feasible, the pump room should be located and constructed so as to protect the pump unit and controls from falling floors or machinery and from fire that could drive away the pump operator or damage the pump unit or controls. Access to the pump room should be provided from outside the building. Where the use of brick or reinforced concrete is not feasible, metal lath and plaster is recommended for the construction of the pump room. The pump room or pump house should not be used for storage purposes. Vertical shaft turbine type pumps might necessitate a removable panel in the pump house roof to permit the pump to be removed for inspection or repair. Proper clearances to equipment should be provided as recommended by the manufacturer's drawings. Additional Proposed Changes File Name Description Approved 20_PI_52_Held_Comment_20-120_Anthony_.pdf Held Comment If a fire pump is on an elevated platform to keep it above a flood level, the bottom of the pump controller should not be below this level. It is recognized that this comment will be held over until the next revision cycle because it presents the committee a new concept. We would like to see this concept tracking in the discussion at any point.

A Fire protection requirements for multi-building campuses may be effectively met with centrally located fire pump facilities. Additional Proposed Changes File Name Description Approved 20_PI_53_Held_Comment_20-125_Anthony_.pdf Held Comment Where environmental conditions permit, modular, pre-packaged fire pump houses driven by diesel generators offer very significant advantages. Among them: 1. Recovery of interior enterprise space in all protected buildings. 2. A diesel generator for an electric fire pump provides an independent source of power. 3. Significantly lower first cost and operations and maintenance cost. There are trade-offs. Despite them, we would like to see centralized, multi-building sprinkler systems tracking more explicitly in this document. It is recognized that this comment will be held over until the next revision cycle because it presents the committee a new concept.

181 Page 173 of 198 Public Input No. 60-NFPA [ Section No. A ] A A reliable power source possesses the following characteristics: (1) The source power plant has not experienced any shutdowns longer than 4 continuous hours in the year prior to plan submittal. NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water -Based Fire Protection Systems, requires special undertakings (i.e., fire watches) when a water-based fire protection system is taken out of service for longer than 4 than 10 hours. If the normal source power plant has been intentionally shut down for longer than 4 hours in the past, it is reasonable to require a backup source of power. (2) Power outages have not routinely been experienced in the area of the protected facility caused by failures in generation or transmission. The standard is not intended to require that the normal source of power be infallible to deem the power reliable. NFPA 20 does not intend to require a back-up source of power for every installation using an electric motor driven fire pump. Note that should the normal source of power fail in a rare event, the impairment procedures of NFPA 25 could be followed to mitigate the fire risk. If a fire does occur during the power loss, the fire protection system could be supplied through the fire department connection. (3) The normal source of power is not supplied by overhead conductors outside the protected facility. Fire departments responding to an incident at the protected facility will not operate aerial apparatus near live overhead power lines, without exception. A backup source of power is required in case this scenario occurs and the normal source of power must be shut off. Additionally, many utility providers will remove power to the protected facility by physically cutting the overhead conductors. If the normal source of power is provided by overhead conductors, which will not be identified, the utility provider could mistakenly cut the overhead conductor supplying the fire pump. (4) Only the disconnect switches and overcurrent protection devices permitted by are installed in the normal source of power. Power disconnection and activated overcurrent protection should only occur in the fire pump controller. The provisions of for the disconnect switch and overcurrent protection essentially require disconnection and overcurrent protection to occur in the fire pump controller. If unanticipated disconnect switches or overcurrent protection devices are installed in the normal source of power that do not meet the requirements of 9.2.2, the normal source of power must be considered not reliable and a back-up source of power is necessary. Typical methods of routing power from the source to the motor are shown in Figure A.9.2. Other configurations are also acceptable. The determination of the reliability of a service is left up to the discretion of the authority having jurisdiction.

182 Page 174 of 198 The 2011 Edition of NFPA 25 revised more than 4 hours to more than 10 hours. While I am not sure the Annex note really makes sense as it would appear, at least it would be technically correct. The Committee may want to further revise the Annex note since the duration in NFPA 25 is not consistent with the 4 hour time period in NFPA 20.

192 Report on Proposals June 2015 NFPA Log #4 John Whitney, Clarke Fire Protection Products, Inc., Russell B. Leavitt, Telgian Corporation Revise text to read as follows: Where environmental or fuel quality conditions result in degradation of the fuel while stored in the supply tank, from items such as water, micro-organisms and particulates, or destabilization, a listed active fuel maintenance system shall be installed to maintain fuel quality. Active fuel maintenance system shall be quipped with a visible indicator to indicate when the system is in need of maintenance. Active fuel maintenance system shall be quipped with contact closure for connect to the controller (ref. par ) to indicate when the system is in need of maintenance. When required the listed active fuel maintenance systems shall be permanently connected to the fuel tank as follows: (1) All connections made directly to the tank ((this language is from current par. A )) (2) The supply from the tank to the maintenance system shall be connected to the bottom of the fuel storage tank. (3) The return from the maintenance system to the fuel storage tank shall be installed as directed by the fuel maintenance system manufacturer. (4) No connections are interconnected with the engine or its fuel supply and return piping in any way. ((This language is from current par. A )) (5) No valves or other devices are added to the engine or its fuel supply and fuel return in any way. ((This language is from current par. A )) Commercial distillate fuel oils used in modern diesel engines are subject to various detrimental effects from storage. The origin of the crude oil, refinement processing techniques, time of year, and geographical consumption location all influence the determination of fuel blend formulas. Sulfur, naturally occurring gums, waxes, soluble metallic soaps, water, dirt, blends and temperature all contribute to the degradation of the fuel as it is handled and stored. These effects begin at the time of fuel refinement and continue until consumption. Proper fuel storage is critical for engine operation, efficiency, and longevity. Storage tanks should be kept water-free. Water contributes to steel tank corrosion and the development of microbiological growth where fuel and water interface. This and the metals of the system provide elements that can react with fuel to form certain gels or organic acids, resulting in clogging of filters and system corrosion. Scheduled fuel maintenance helps to reduce fuel degradation. Fuel maintenance filtration can remove contaminants and water and maintain conditions to provide reliability and efficiency for standby fire pump engines. Fuel maintenance and testing should begin the day of installation and first fill. In addition to an active fuel maintenance system a fuel stabilizer or other additives may be necessary to insure quality fuel for engine operation. Consult your active fuel maintenance system supplier or fuel supplier for guidance regarding fuel additives and maintenance requirements for long term storage. Low fuel level. Fuel supply trouble. Signal at two-thirds tank capacity, or when active fuel maintenance system needs maintenance. The characteristics of diesel fuel are changing and proper storage is becoming extremely important to insure reliable operation of engines. Even when the proper fuel has been purchased and put into the fuel storage tank long term reliability can not be assumed. For reasons as explained in the proposed annex text and governmental mandated addition of various blends of bio-fuel, diesel fuel is requiring additional attention to insure reliable use in diesel engines for stand-by service. Revise text to read as follows: Where environmental or fuel quality conditions result in degradation of the fuel while stored in the supply tank from items such as water, micro-organisms and particulates, or destabilization, A listed active fuel maintenance system shall be installed to maintain fuel quality with all fuel storage tanks. When required, The listed active fuel maintenance system shall be permanently connected to the fuel tank as follows: Printed on 1/25/2013 1

193 Report on Proposals June 2015 NFPA 20 This entire section reads as a reactive action. It states that Where environmental or fuel quality conditions result [emphasis added] in degradation... Reactive actions are not appropriate for an installation standard and should be assigned to NFPA 25. If the intent is for the installer to somehow make a determination that the conditions exist from the onset, then how is that determined? The committee must either explain how to determine the conditions exist for degradation and then add the word could before result in degradation of the fuel or require it for all fuel storage tanks. If the problem is as pervasive as the committee seems to believe, then it should be a requirement for all storage tanks. This proposal and comment were returned to Committee at the A2012 Association Technical Meeting and/or subsequent Standards Council Meeting.

198 Page 188 of 198 Public Input No. 121-NFPA [ Section No. A ] A The test procedure is as follows: (1) Make a visual check of the unit. If hose and nozzles are used, see that they are securely tied down. See that the hose valves are closed. If a test meter is used, the valve on the discharge side of the meter should be closed. (2) Start the pump. (3) Partially open one or two hose valves, or slightly open the meter discharge valve. (4) Check the general operation of the unit. Watch for vibration, leaks (oil or water), unusual noises, and general operation. Adjust packing glands. (5) Measure water discharge. The steps to do so are as follows: (a) (b) (c) Where a test valve header is used, regulate the discharge by means of the hose valves and a selection of the nozzle tips. It will be noticed that the play pipe has a removable tip. This tip has a in. (28.6 mm) nozzle, and when the tip is removed, the play pipe has a in. (44.4 mm) nozzle. Hose valves should be shut off before removing or putting on the in. (28.6 mm) tip. Where a test meter is used, regulate the discharge valve to achieve various flow readings. Important test points are at 150 percent rated capacity, rated capacity, and shutoff. Intermediate points can be taken if desired to help develop the performance curve. (6) Record the following data at each test point (see Figure A ): (a) (b) (c) (d) (e) (f) Pump rpm Suction pressure Discharge pressure Number and size of hose nozzles, pitot pressure for each nozzle, and total gpm (L/min); for test meter, simply a record of gpm (L/min) Amperes (each phase) Volts (phase to phase) (7) Calculation of test results is as follows: (a) Rated Speed. Determine that pump is operating at rated rpm.

199 Page 189 of 198 (b) (c) Capacity. For hose valve header, using a fire stream table, determine the gpm (L/min) for each nozzle at each pitot reading. For example, 16 psi (1.1 bar) pitot pressure with in. (44.4 mm) nozzle indicates 364 gpm (1378 L/min). Add the gpm for each hose line to determine total volume. For test meter, the total gpm (L/min) is read directly. Total Head for Horizontal Pump. Total head is the sum of the following: i. Pressure measured by the discharge gauge at pump discharge flange ii. Velocity head difference, pump discharge, and pump suction velocity head= h v = V 2 /2g iii. Gauge elevation corrections to pump centerline (plus or minus) iv. Pressure measured by suction gauge at pump suction flange negative value when pressure is above zero (a) Total Head for Vertical Pump. Total head is the sum of the following: (8) Pressure measured by the discharge gauge at pump discharge flange (9) Velocity head at the discharge (10) Distance to the supply water level (11) Discharge gauge elevation correction to centerline of discharge (12) Electrical Input. Voltage and amperes are read directly from the volt/ammeter. This reading is compared to the motor nameplate full -load amperes. The only general calculation is to determine the maximum amperes allowed due to the motor service factor. In the case of 1.15 service factor, the maximum amperes are approximately 1.15 times motor amperes, because changes in power factor and efficiency are not considered. If the maximum amperes recorded on the test do not exceed this figure, the motor and pump will be judged satisfactory. It is most important to measure voltage and amperes accurately on each phase should the maximum amperes logged on the test exceed the calculated maximum amperes. This measurement is important because a poor power supply with low voltage will cause a high ampere reading. This condition can be corrected only by improvement in the power supply. There is nothing that can be done to the motor or the pump.

200 Page 190 of 198 (13) Correction to Rated Speed. For purposes of plotting, the capacity, head, and power should be corrected from the test values at test speed to the rated speed of the pump. The corrections are made as follows. Capacity: where: Q 1 = capacity at test speed in gpm (L/min) Q 2 = capacity at rated speed in gpm (L/min) N 1 = test speed in rpm N 2 = rated speed in rpm Head: where: H 1 = head at test speed in ft (m) H 2 = head at rated speed in ft (m) Horsepower: where: hp 1 = kw (horsepower) at test speed hp 2 = kw (horsepower) at rated speed (14) Conclusion. The final step in the test calculation is generally a plot of test points. A head-capacity curve is plotted, and an amperecapacity curve is plotted. A study of these curves will show the performance picture of the pump as it was tested. Figure A Centifugal Fire Pump Acceptance Test Form. (Source: National Fire Sprinkler Association, Inc.)

204 Page 194 of 198 (b) (c) Capacity. For hose valve header, using a fire stream table, determine the gpm (L/min) for each nozzle at each pitot reading. For example, 16 psi (1.1 bar) pitot pressure with in. (44.4 mm) nozzle indicates 364 gpm (1378 L/min). Add the gpm for each hose line to determine total volume. For test meter, the total gpm (L/min) is read directly. Total Head for Horizontal Pump. Total head is the sum of the following: i. Pressure measured by the discharge gauge at pump discharge flange ii. iii. iv. Velocity head difference, pump discharge, and pump suction Gauge elevation corrections to pump centerline (plus or minus) Pressure measured by suction gauge at pump suction flange negative value when pressure is above zero (d) Total Head for Vertical Pump. Total head is the sum of the following: i. Pressure measured by the discharge gauge at pump discharge flange ii. iii. iv. Velocity head at the discharge Distance to the supply water level Discharge gauge elevation correction to centerline of discharge (e) (f) Electrical Input. Voltage and amperes are read directly from the volt/ammeter. This reading is compared to the motor nameplate full -load amperes. The only general calculation is to determine the maximum amperes allowed due to the motor service factor. In the case of 1.15 service factor, the maximum amperes are approximately 1.15 times motor amperes, because changes in power factor and efficiency are not considered. If the maximum amperes recorded on the test do not exceed this figure, the motor and pump will be judged satisfactory. It is most important to measure voltage and amperes accurately on each phase should the maximum amperes logged on the test exceed the calculated maximum amperes. This measurement is important because a poor power supply with low voltage will cause a high ampere reading. This condition can be corrected only by improvement in the power supply. There is nothing that can be done to the motor or the pump. Correction to Rated Speed. For purposes of plotting, the capacity, head, and power should be corrected from the test values at test speed to the rated speed of the pump. The corrections are made as follows. Capacity: where:

205 Page 195 of 198 Q 1 = capacity at test speed in gpm (L/min) Q 2 = capacity at rated speed in gpm (L/min) N 1 = test speed in rpm N 2 = rated speed in rpm Head: where: H 1 = head at test speed in ft (m) H 2 = head at rated speed in ft (m) Horsepower: where: hp 1 = kw (horsepower) at test speed hp 2 = kw (horsepower) at rated speed (g) Conclusion. The final step in the test calculation is generally a plot of test points. A head-capacity curve is plotted, and an amperecapacity curve is plotted. A study of these curves will show the performance picture of the pump as it was tested. Figure A Centifugal Fire Pump Acceptance Test Form. (Source: National Fire Sprinkler Association, Inc.)
