1 of 1374 6/30/2016 11:10 AM Public Input No. 210-NFPA 72-2016 [ Global Input ] Rewrite the "Exception" text throughout NFPA 72 and replace with standard subsection text. NFPA 72 contains numerous sections that are written with "Exception" text. This is inconsistent the direction provided in the Manual of Style and should be corrected. Differing types of style that are inconsistent with the MOS create confusion as the proper application of the code by the end user. As an example, 10.4.4 is currently written with an "exception" as follows: "10.4.4* In areas that are not continuously occupied, automatic smoke detection shall be provided at the location of each fire alarm control unit(s), notification appliance circuit power extenders, and supervising station transmitting equipment to provide notification of fire at that location. Exception: Where ambient conditions prohibit installation of automatic smoke detection, automatic heat detection shall be permitted." This section could easily be rewritten to be consistent with the MOS in the following manner with the exception becoming core text in a subsection modifying 10.4.4: 10.4.4* In areas that are not continuously occupied, automatic smoke detection shall be provided at the location of each fire alarm control unit(s), notification appliance circuit power extenders, and supervising station transmitting equipment to provide notification of fire at that location. 10.4.4.1 Where ambient conditions prohibit installation of automatic smoke detection, automatic heat detection shall be permitted. The above is just one example but applies throughout to all "exception" text in NFPA 72.

This proposal merely moves UL standards from Section 2.3.1 ANSI Publications to a new Section 2.3.6 titled UL Publications. Other NFPA codes such as NFPA 101, 13, etc. treat UL referenced standards in this same manner. The move will make it easier for code users to locate UL referenced standards. Assume existing Section 2.3.6 will be renumbered 2.3.7. In separate public inputs we proposed updates to UL referenced standards, and introduced new referenced standards. If those changes are accepted they should be relocated to this section. Also assume staff can delete these ANSI/UL standards are deleted from Section 2.3.1.

A.3.2.x Enforcing Authority. An enforcing authority may also be an authority having jurisdiction (AHJ). The enforcing authority may be an individual within the agency or organization assigned to carry out the duties and responsibilities of the enforcing authorities including developing regulations supported by the enforcing authority. This work is the results of a task group consisting of Lynn Nielson (chair), Art Black, Andrew Berezowski, Warren Olsen and Rodger Reiswig. Several cycles ago, the TCC at the time use of the term Enforcing Authority, where appropriate, to differentiate between an AHJ - who can be any entity responsible for approving something, including an owner - and the AHJ (Enforcing Authority) who has a legal or governmental responsibility for enforcing NFPA 72. This work is In accordance with the NFPA MOS. "Multiple Meanings. All words and terms used in NFPA documents that could be used, understood, or interpreted in more than one way shall be defined in the definitions chapter". This term is used in the following sections: 18.1.1; 18.1.5; 18.4.7.3; 18.4.7.4; 18.4.7.4; 18.4.10.3; 18.11.

101 of 1374 6/30/2016 11:10 AM Public Input No. 624-NFPA 72-2016 [ Section No. 3.3.172.3 ] 3.3.172.3 Visible Visual Notification Appliance. A notification appliance that alerts by the sense of sight. (SIG-NAS) 3.3.172.3.1* Textual Visible Notification Appliance. A notification appliance that conveys a stream of visible information that displays an alphanumeric or pictorial message. (SIG-NAS) The term Visible Notification Appliance is used a total of 85 times in the 2016 edition of NFPA 72, the first of which is in 3.3.172.3. It is used 3 times in the Origin and Development of NFPA 72, 47 times in the body of the Code, and 35 times in the Annex of the Code. Additionally, the term Visible Notification (without the term appliance ) is used 19 times in the body and Annex of the Code. The term Visual Notification Appliance is used a total of 4 times in the 2016 edition of NFPA 72, once in the body of the code at 18.5.5.4.2(3) and 3 times in the Annex of the Code. Additionally, the term Visual Notification is used once in the Annex of the Code (A.24.5.18.2). This proposal seeks to change and standardize on the term Visual Notification Appliance or Visual Notification throughout the body and Annex of the Code (all 104 uses). The term visible is defined by Merriam-Webster as able to be seen or know to or noticed by the public. The term visual is defined by Merriam-Webster as relating to seeing or to the eyes. As such the term visual is much more accurate in the defining the purpose and action of an appliance that alerts by the sense of sight. By definition, a visible device must be seen. The opposite of visible is invisible, whereas the opposite of visual is audible; since there is no such thing as an invisible device, the term visual is much more appropriate as compared to audible devices in the Code. Currently, these terms are used somewhat interchangeably and this proposal seeks to standardize on just one term. This standardization on the term Visual Notification Appliance becomes more significant considering other Public Inputs being proposed by the UL STP Task Group on Indirect Viewing of Visual Signals. This task group is defining the terms direct visual alerting and indirect visual alerting, which is by nature defining whether a visual device is directly visible or not; therefore, the term Visible Notification Appliance would no longer be accurate if such proposals are approved. In other words, it is possible to provide alerting through the use of a Visual Notification Appliance that is not visible via the use of reflected light (i.e., indirect viewing). It should be noted that the term Textual Visible Notification Appliance is used a total of 7 times in the 2016 edition of NFPA 72, the first of which is in 3.3.172.3.1. It is used 5 times in the body of the Code and 2 times in the Annex of the Code. This public input does not seek to change the use of this term as a Textual Visible Notification Appliance, such as an annunciator, monitor, CRT, display or printer, must be visible to be understood. Alerting with these devices requires the appliance to be visible, although in the strictest sense of the term they are by nature a visual device. As such, the technical committee may want to consider the adjustment of this term to be consistent with all other visual notification appliances.

744 of 1374 6/30/2016 11:10 AM Public Input No. 712-NFPA 72-2016 [ New Section after 18.3.2 ] Voltage Drop Calculations 18.3.2.4 Voltage drop calculations shall be performed using one of the following methods: (1) The lump sum calculation method, which shall be calculated as follows: (a) Calculate the voltage drop using one of these formulas: i. VD = I * ((R * 2 * L)/1,000) OR ii. VD = (2 * K * I * L)/CM. (b) Subtract this calculated voltage drop from 20.4 volts (VS) in order to get the voltage value at the end of the circuit (VS VD = VEOL). The value for VEOL shall be a minimum of 16 volts (the minimum operating voltage required for a listed 24 vdc notification device). (2) The point-to point method, which requires a math-intensive approach where the voltage drop between each notification appliance is reiterated. This method is best done by utilizing a spreadsheet program. The calculated voltage at the last device on the circuit shall be a minimum of 16 volts (the minimum operating voltage required for a listed 24 vdc notification device). Where: VD = Voltage Drop VS = Starting voltage (20.4vdc, or the end of useful battery life) VEOL = Voltage at the end-of-line resistor I =Total load of the circuit in amperes utilizing current draws for each notification appliance @ 16vdc (the UL maximum draws at the minimum listed voltage). R = Resistance in ohms per 1,000 feet, with respect to conductor K = 10.64 ohms (the constant representing the mil-foot resistance of copper wire) L = length of circuit in feet (distance from panel to end-of-line resistor for class B circuits) CM = circular mill of wire, with respect to conductor. VSOURCE = voltage calculated at the previous device (3) Other methods acceptable to the authority having jurisdiction such as the center-load calculation method. This is intended to standardize the way in which designers calculate voltage drops for notification circuits. The methods shown on this proposal in calculating voltage drops are consistent with the methods described in the narrative of the NFPA 72 Fire Alarm Code Handbook. The base code for NFPA 72 does not provide guidance with regards to the methods to use when calculating voltage drops.

For buildings other than those with dwelling units, due to the varying building size and use, the danger of carbon monoxide exposure is only in the area of coverage. Visible notification should be limited to that area to limit the evacuation and disruption to the entire building s operation or business, and is to be documented as such in the emergency response plan for the protected premises.

Exception: Lights used to meet the requirements of 18.5.5.5 shall be permitted to be listed and labeled to have pulse durations up to 100 milliseconds. Duty cycle is calculated using the pulse duration and the flash rate (previous paragraph). Therefore, having this text is redundant. The 40% MAX duty cycle came from 2013 and prior editions that allowed 200 ms pulse duration. Using 200 ms with the max. of 2 flashes per sec.: 0.2 s pulse / 0.5 s period = 0.4 duty cycle = 40%. Since the 2016 edition allows 100 ms (down from 200 ms) for direct viewing, we should have reduced the max. duty cycle to 20%. But, there is no need to TIA the 2016 edition since 20% is still less than a max. of 40%. Submitter Full Name: Robert Schifiliti Organization: R. P. Schifiliti Associates, Inc.

Exception: Lights used to meet the requirements of 18.5.5.5 shall be permitted to be listed and labeled to have pulse durations up to 100 milliseconds. The duty cycle currently in the code is not correct for the prescribed pulse duration. The maximum duty cycle is 4 percent for a 20 millisecond pulse duration for a flash rate of two times per second and not 40 percent (calculated as 20 milliseconds divided by 500 milliseconds). The 4 percent requirement, in the submitter s opinion is unnecessary as the requirement of a 20 millisecond maximum pulse width and the requirement of a maximum of two flashes per second ensures a maximum duty cycle of 4% and this added requirement is redundant.

1110 of 1374 6/30/2016 11:10 AM All parts of a building or area intended to have occupant notification are subdivided into ADSs as defined. Some ADSs might be designated to have voice communication communications capability and require that those communications be intelligible. Other spaces might not require voice intelligibility or might not be capable of reliable voice intelligibility. An ADS might have acoustical design features that are conducive for voice intelligibility, or it might be a space where voice intelligibility could be difficult or impossible to achieve. Each is still referred to as an ADS. In smaller areas, such as those under 400 ft 2 (40 m 2 ), walls alone will define the ADS. In larger areas, other factors might have to be considered. In spaces that might be subdivided by temporary or movable partitions, such as ballrooms and meeting rooms, each individual configuration should be considered a separate ADS. Physical characteristics, such as a change in ceiling height of more than 20 percent, or a change in acoustical finish, such as carpet in one area and tile in another, would require those areas to be treated as separate ADSs. In larger areas, there might be noise sources that require a section to be treated as a separate ADS. Any significant change in ambient noise level or frequency might necessitate an area be considered a separate ADS. In areas of 85 dba or greater ambient sound pressure level, meeting the pass/fail criteria for intelligibility might not be possible, and other means of communication communications might be necessary. So, for example, the space immediately surrounding a printing press or other high-noise machine might be designated as a separate ADS, and the design might call for some form of effective notification but not necessarily require the ability to have intelligible voice communication communications. The aisles or operator s control stations might be separate ADSs where intelligible voice communication might be desired. Significant differences in furnishings, for example, an area with tables, desks, or low dividers, adjacent to an area with high shelving, would require separate consideration. The entire desk area could be a single acoustic zone, whereas each area between shelving could be a unique zone. Essentially, any noteworthy change in the acoustical environment within an area will mandate consideration of that portion of the area to be treated as an acoustic zone. Hallways and stairwells will typically be considered as individual acoustic zones. Spaces confined by walls with carpeting and acoustical ceilings can be deemed to be one ADS. An ADS should be an area of consistent size and material. A change of materials from carpet to hard tile, the existence of sound sources, such as decorative waterfalls, large expanses of glass, and changes in ceiling height, are all factors that might separate one ADS from another. Each ADS might require different components and design features to achieve intelligible voice communication. For example, two ADSs with similar acoustical treatments and noise levels might have different ceiling heights. The ADS with the lower ceiling height might require more ceiling-mounted speakers to ensure that all listeners are in a direct sound field (see Figure A.3.3.6). Other ADSs might benefit from the use of alternate speaker technologies, such as line arrays, to achieve intelligibility. An ADS that differs from another because of the frequency and level of ambient noise might require the use of speakers and system components that have a wider frequency bandwidth than conventional emergency communications equipment. However, designers should not use higher bandwidth speakers in all locations, unless needed to overcome certain acoustic and ambient conditions. This is because the higher bandwidth appliance will require more energy to perform properly. This increases amplifier and wire size and power supply requirements. In some spaces, it might be impractical to achieve intelligibility, and, in such a case, alternatives to voice evacuation might be required within such areas. Figure A.3.3.6 Illustration Demonstrating the Effect of Ceiling Height. (Source: R. P. Schifiliti Associates, Inc.) There might be some areas of a facility where there are several spaces of the same approximate size and the same acoustic properties. For example, there might be an office space with multiple individual offices, each with one speaker. If one or two are satisfactorily tested, there is no need to test all of them for speech intelligibility.

Every time the distance from the source doubles, the sound level decreases by about 6 decibels (db). Audible notification appliances are typically rated by manufacturers' and testing agencies at 10 ft (3 m) from the appliance. Subsequently, at a distance of 20 ft (6.1 m) from an audible appliance rated at 84 dba, the sound level might be reduced to 78 dba. At a closed door, the loss might be about 10 db to 24 db or more depending on construction. If the opening around the door is sealed, this might result in a loss of 22 db to 34 db or more. The reference table in the Annex is a reference of expected and typical ambient sound levels in certain locations. This table has been in the Annex for multiple code cycles. Submitter believes this to be a useful reference for designers to determine audible requirements in a specific occupancy. As such, this table should be reviewed and updated as appropriate. The submitted updates are based upon recent published reports from the Department of Health and Human Services, Centers for Disease Control and Prevention and reflect current approximations for typical ambient sound levels in certain locations. In circumstances where multiple measurements were possible, submitter used an average but excluded the maximum and minimum values. In circumstances where two measurements were available, submitter selected value closest to existing measurement. Submitter Full Name: Thomas Hammerberg

If mounted too low, the illumination is greater (brighter) but the pattern is smaller and might not overlap correctly with that of adjacent appliances. A qualified designer could choose to present calculations to an authority having jurisdiction showing that it is possible to use a mounting height greater than 96 in. (2.44 m) or less than 80 in. (2.03 m), provided that an equivalent level of illumination is achieved on the adjacent surfaces. This can be accomplished by using listed higher intensity appliances or closer spacing, or both. Engineering calculations should be prepared by qualified persons and should be submitted to the authority having jurisdiction, showing how the proposed variation achieves the same or greater level of illumination provided by the prescriptive requirements of Section 18.5. The calculations require knowledge of calculation methods for high-intensity strobes visible notification appliances. In addition, the calculations require knowledge of the test standards used to evaluate and list the appliance. As part of the CC TG on terms, the term "light" and strobe was reviewed throughout the entire document for proper use. In some cases it refers to a physical appliance while other sections use it to refer to the output of an appliance. In this section the term is for an appliance and the proper term "visible notification appliance" should be used.

Whole building evacuation might not be specified in the emergency response plan. For providing clarity to body of the same section. For buildings other than those with dwelling units, due to the varying building size and use, the danger of carbon monoxide exposure is only in the area of coverage. Visible notification should be limited to that area to limit the evacuation and disruption to the entire building s operation or business, and is to be documented as such in the emergency response plan for the protected premises.

Until additional work is done and incorporated into this Code, lights visible notification appliances used for indirect signaling and having effective intensities specified in Table 18.5.5.4.1(a) or Table 18.5.5.4.1(b) need to be short duration, high intensity to be effective for the specified area of coverage. This limitation does not apply to direct signaling such as that used in corridors in accordance with 18.5.5.5. For direct signaling in corridors (18.5.5.5), longer pulse appliances (up to 100 ms), such as LED lights, have been shown to be effective. Longer pulse durations might also be effective in large volume spaces that use direct signaling, as discussed in A.18.5.4. As part of the CC TG on terms, the term "light" was reviewed throughout the entire document for proper use.

The units of effective intensity are expressed in candelas (or candlepower, which is equivalent to candelas). For example, a flashing light visible notification appliance that has an effective intensity of 15 cd has the same apparent brightness to an observer as a 15 cd steady-burning light source. Measurement of effective intensity is usually done in a laboratory using specialized photometric equipment. Accurate field measurement of effective intensity is not practical. Other units of measure for the intensity of flashing lights visible notification appliances, such as peak candela or flash energy, do not correlate directly to effective intensity and are not used in this standard. Strobe lights appliances might be used to signal fire or other emergencies and might be intended to initiate evacuation, relocation, or some other behavior. Lights Visible notification appliances intended to initiate evacuation due to fire are required by the Code to be clear or white. Colored lights visible notification appliancevisible notification appliances, such as amber/yellow lights appliances, might be used in a combination system for any emergency (fire, bomb, chemical, weather, etc.) when the intent is for the signal recipient to seek additional information from other sources (voice, text displays, and so on). Example Scenario 1: A building has a fire alarm system used for general evacuation. A separate mass notification system is used to provide voice instructions and information in the event of non-fire emergencies. The fire alarm system would have white/clear strobes strobe appliances intended to alert occupants of the need to evacuate. The mass notification system would have amber/yellow strobes strobe appliances that are intended to signal the need to get additional information from either audible voice announcements, text or graphical displays, or other information sources controlled or operated from the mass notification system. In the event that both systems are activated at the same time, the strobes visible notification appliances should be synchronized per 18.5.5.4.2. Example Scenario 2: A building has a mass notification system that provides information and instructions for a variety of emergency situations, including fire. Fire alarm initiation might be by a stand-alone fire detection system or might be an integral part of the mass notification system. In the event of an emergency, textual audible appliances are used to provide information. Visible alerting could be accomplished using one set of clear or colored strobes visible notification appliances to indicate the need to get additional information. Visible textual information can be provided by text or graphic display or other visible information appliances. The content of the audible and visible messages will vary depending on the emergency.

1206 of 1374 6/30/2016 11:10 AM The prescriptive requirements of Section 18.5 assume the use of appliances having very specific characteristics of light color, intensity, distribution, and so on. The appliance and application requirements are based on extensive research. However, the research was limited to typical residential and commercial applications such as school classrooms, offices, hallways, and hotel rooms. While these specific appliances and applications will likely work in other spaces, their use might not be the most effective solution and might not be as reliable as other visible notification methods. For example, in large warehouse spaces and large distribution spaces such as super stores, it is possible to provide visible signaling using the appliances and applications of this chapter. However, mounting strobe lights visible notification appliances at a height of 80 in. to 96 in. (2.03 m to 2.44 m) along aisles with rack storage subjects the lights visible notification appliances to frequent mechanical damage by forklift trucks and stock. Also, the number of appliances required would be very high. It might be possible to use other appliances and applications not specifically addressed by this chapter at this time. Alternative applications must be carefully engineered for reliability and function and would require permission of the authority having jurisdiction. Tests of a system in large warehouse/super stores designed using the prescriptive approach of 18.5.5.4 showed that high ambient light levels resulted in both indirect and direct signaling effects. The signalto-noise ratio produced by the operating visible notification appliances was low in many locations. However, with visible notification appliances located over the aisles or unobstructed by stock, indirect and some direct notification was sometimes achieved. Direct notification occurs even when occupants do not look up toward the ceiling-mounted visible notification appliances due to the extended cone of vision shown in Figure A.18.5.4(a). The visible notification appliance intensity and spacing resulting from the prescriptive design was generally sufficient for occupant notification by a combination of direct and indirect signaling. Testing showed that the best performance was achieved where visible notification appliances were directly over aisles or where visible notification appliances in adjacent aisles were not obstructed by stock. The performance-based design method will almost always result in aisles not having a line of visible notification appliances in them, because the spacing of visible notification appliances can be greater than the spacing of aisles. Also, it is recognized that aisles might be relocated after installation of the system. Good design practice is to place visible notification appliances over aisles, especially those that are likely to remain unchanged such as main aisles, and over checkout areas. Where reorganization of aisles results in visible notification appliances not in or over an aisle, or where that is the base design, it is important to have a clear view from that aisle to a nearby visible notification appliance. See Figure A.18.5.4(b). Some spaces might have marginal visible notification appliance effect (direct or indirect). However, occupants in these large stores and storage occupancies move frequently and place themselves in a position where they receive notification via the visible notification appliances. In addition, complete synchronization of the visible notification appliances in the space produced a desirable effect. Visible notification using the methods contained in 18.5.5.4 is achieved by indirect signaling. This means the viewer need not actually see the appliance, just the effect of the appliance. This can be achieved by producing minimum illumination on surfaces near the appliance, such as the floor, walls, and desks. There must be a sufficient change in illumination to be noticeable. The tables and charts in Section 18.5 specify a certain candela-effective light intensity for certain size spaces. The data were based on extensive research and testing. Appliances do not typically produce the same light intensity when measured off-axis. To ensure that the appliance produces the desired illumination (effect), it must have some distribution of light intensity to the areas surrounding the appliance. ANSI/UL 1971, Standard for Signaling Devices for the Hearing Impaired, specifies the distribution of light shown to provide effective notification by indirect visible signaling.
