28 of 326 11/21/2013 1:03 PM First Revision No. 92-NFPA 72-2013 [ Section No. 12.2.4.2 ] 12.2.4.2 All non-power-limited and power-limited signaling system circuits entering a building shall be provided with transient protection. (SIG-FUN) Submittal Date: Mon Sep 09 11:25:18 EDT 2013 This new requirement added in 2013 is incomplete, unclear and potentially dangerous. The NEC recognizes that not all outside circuits require special transient suppression. There are two reasons for this. The first is that not all circuits that enter or exit a building are prone to lightning or other surge events. Therefore, the NEC qualifies which circuits require transient protection. The second reason that not all circuits that enter or exit a building are required to have transient protection is that adding surge suppression can actually attract lightning if not properly installed and may actually defeat protection that is built into the control units. Listing requirements for control panels already require some measure of transient protection for all circuits. Where additional transient protection is installed on both ends of a circuit which extends between two buildings, unless the grounding is to the same point or at the same potential there will be ground loops that will attract surges and damage systems. Additional transient protection beyond that required by the product listing should only be required in areas that are prone to lightning - as already required by the NEC. In addition, the requirement does not specify whether the transient protection should be of the parallel type or the serial type, which affects whether the circuit will continue to operate upon catastrophic failure of the protection device. For example, in most cases a parallel type should be used for initiating device circuits and signaling line circuits. This will permit those circuits to continue to operate if the device has been destroyed by the first strike. This can be important if that same lightning strike actually started a fire which could be detected if the detection or signaling circuit continued to operate. If a serial type had been used, the circuit might no longer be operational and would fail to detect the fire even though the panel would be protected against a second potential strike. There is a lot more thought, planning and design needed to properly specify transient protection. This 2013 requirement goes beyond the minimum requirements of a code or standard such as NFPA 72. NFPA 72 already requires compliance with the appropriate sections of the NEC. Public Input No. 514-NFPA 72-2013 [Section No. 12.2.4.2]
29 of 326 11/21/2013 1:03 PM First Revision No. 156-NFPA 72-2013 [ New Section after 12.2.4.4 ] 12.2.3.4* Where operational capability is required to be maintained or continued during the application of a fault, the operational capability required in Section 10.11 and 23.8.1.1 shall be restored within 200 seconds from the time the fault is introduced. Supplemental Information File Name A.12.2.4.5_for_FR_156_EC_edits.docx Description Submittal Date: Wed Sep 11 10:38:55 EDT 2013 Paragraphs 12.2.5.2, 12.3.1(2), 12.3.1(4), 12.3.2(4), 12.3.6(2), 12.3.6(3), 12.3.6(4), and 12.3.6(6) require operational capability to be maintained or continued during the application of various identified faults single open, single ground, wire to wire (short) etc. This is to clarify when the operational capability is to begin after the introduction of the fault condition. The issue is the application of two events fault and alarm in rapid succession. The Code permits each event to have a different response time. Faults = 200 s and alarms = 10 s. Because a fault affects the circuit performance until detected and the circuit is automatically reconfigured, this is a hardware issue rather than just a software issue. Systems technology needed to process these two events in the order of occurrence. Where a fault is applied first, the system is permitted up to 200 s to detect and automatically reconfigure. Any alarm applied after 200 s is required to be annunciated and to actuate required signals within 10 s. This is a minimum requirement and systems may process the signals faster. The change will correlate with proposed changes to ANSI/UL 864. This change also adds new annex material - A.12.2.4.5
A.12.2.4.5 In the event of an introduction of a fault and subsequent alarm condition, operational ability should be restored within 200 seconds, and the alarm condition received at the fire alarm control unit is to be within 10 seconds after the expiration of the 200 seconds. Any subsequent alarms initiated after the initial 200 second window should be actuated in accordance with Section 10.11 and 23.8.1.1.

A pathway shall be designated as Class C when it performs as follows: (1) It includes one or more pathways where operational capability is verified via end-to-end communication, but the integrity of individual paths is not monitored. (2) A loss of end-to-end communication is annunciated as a trouble signal. Submittal Date: Mon Sep 09 12:28:00 EDT 2013 The purpose of this change is to clarify that section 12.3.3 requires a trouble signal and make it consistent with the other paragraphs in this section.

Exception: When only one device is served, only one pathway shall be required. (2) A loss of intended communications between endpoints shall be annunciated as a trouble signal. (3) A single open, ground, short, or combination of faults on one pathway shall not affect any other pathway. (4)* Conditions that affect the operation of the primary pathway(s) and redundant pathway(s) shall be annunciated as a trouble signal when the system s minimal operational requirements cannot be met. (5) * Primary and redundant pathways shall not be permitted to share traffic over the same physical segment. Submittal Date: Mon Sep 09 14:06:18 EDT 2013 Questions concerning the acceptability of using Ethernet and other non-fire or non-mns networks for fire alarm and signaling systems applications are being raised more and more. Because of these questions and the rapidly changing technology, the Task Group on Networks in FA/ECS was formed by the Correlating to address the risk analysis, design, application, installation, and performance of networks and networking equipment used in fire alarm systems, fire EVACS and mass notification systems. This change is a result of that effort. Some of the concerns that were raised during related discussions for the 2013 edition included: ground detection, system management, availability, and software control. Also see FR 101 and FR 103 for related annex material and associated figures.

The outgoing and return (redundant) circuit conductors shall be permitted in the same cable assembly (i.e., multi-conductor multiconductor cable), enclosure, or raceway only under the following conditions: (1) For a distance not to exceed 10 ft (3.0 m) where the outgoing and return conductors enter or exit the initiating device, notification appliance, or control unit enclosures (2) For single raceway drops Single drops installed in raceway to individual devices or appliances (3)* For single raceway drops to multiple devices or appliances installed within In a single room not exceeding 1000 ft 2 (93 m 2 ) in area, a drop installed in raceway to multiple devices or appliances that does not include any emergency control function devices Submittal Date: Mon Sep 09 15:15:25 EDT 2013 Changes are made for clarity. Class N circuits were added to correlate with other FRs. Sections 12.3.7(3) now excludes primary and secondary conductors to emergency control function devices from being permitted in the same cable assembly, enclosure or raceway. Changes to subparagraphs (2) and (3) were made to clarify the intent that only single drops in raceway are acceptable. Where a circuit enters a room that contains emergency control function interface devices (i.e., control modules/relays connected to and programmed to shutdown HVAC units and other fire and life safety control functions), loss of both "legs" of this circuit could disable important fire and life safety control functions that might be essential for prevention of circulation of smoke or some other required operation, such as elevator recall functions.
First Revision No. 212-NFPA 72-2013 [ Section No. 12.4 ] 12.4* Pathway Survivability. All pathways shall comply with NFPA 70, National Electrical Code. 12.4.1 Pathway Survivability Level 0. Level 0 pathways shall not be required to have any provisions for pathway survivability. 12.4.2 Pathway Survivability Level 1. Pathway survivability Level 1 shall consist of pathways in buildings that are fully protected by an automatic sprinkler system in accordance with NFPA 13, Standard for the Installation of Sprinkler Systems, with any interconnecting conductors, cables, or other physical pathways installed in metal raceways. 12.4.3* Pathway Survivability Level 2. Pathway survivability Level 2 shall consist of one or more of the following: (1) 2-hour fire-rated circuit integrity (CI) or fire-resistive cable (2) 2-hour fire-rated cable system [electrical circuit protective system(s)] (3) 2-hour fire-rated enclosure or protected area (4)* 2-hour performance Performance alternatives approved by the authority having jurisdiction 12.4.4 Pathway Survivability Level 3. Pathway survivability Level 3 shall consist of pathways in buildings that are fully protected by an automatic sprinkler system in accordance with NFPA 13, Standard for the Installation of Sprinkler Systems, and one or more of the following: (1) 2-hour fire-rated circuit integrity (CI) or fire-resistive cable (2) 2-hour fire-rated cable system [electrical circuit protective system(s)] (3) 2-hour fire-rated enclosure or protected area (4)* 2-hour performance Performance alternatives approved by the authority having jurisdiction Supplemental Information File Name Annex_Material_for_FR_212.EC_edits.1382627693497.docx Description Submittal Date: Wed Sep 18 11:36:03 EDT 2013 There is no intention to recommend a certain hierarchical ranking. Also text has been revised to indicate that any performance analysis accepted by the AHJ is acceptable in lieu of the prescriptive requirements for level 2 and 3. Annex material has been added to further clarify these issues. 35 of 326 11/21/2013 1:03 PM
A.12.4 The intent of the pathway survivability designation is to provide options for the protection of the pathway circuits and not to create a hierarchical ranking. Other chapters within NFPA 72 or other codemaking jurisdictions can select the survivability option that best meets their needs. A.12.4.3 Methods of survivability protection might alternate within a protected premise. For example, 2 hour resistive cable might extend from a 2 hour fire rated enclosure. A.12.4.3(4) A performance based alternative is needed because it is possible to construct a nonsprinklered, Type V(000) building that employs relocation or partial evacuation (e.g., a single story ambulatory health care occupancy) that would not warrant either a 2 hour fire resistance rated enclosure or 2 hour cable. Examples of performance alternatives that might be considered in a design for survivability are a strategic application of Class A, Class X, or Class N segments and also wireless communication pathways. A.12.4.4(4) A performance based alternative is needed because it is possible to construct a sprinklered single story Type V(111) or multistory Type II(111) building that employs relocation or partial evacuation (e.g., a health care occupancy) that would not warrant either a 2 hour fire resistance rated enclosure or 2 hour cable (a 1 hour enclosure would suffice). Examples of performance alternatives that might be considered in a design for survivability are a strategic application of Class A, Class X, or Class N segments and also wireless communication pathways.

The proposed figure is a revision of one that has made it through the first draft of NFPA 4. Although NFPA 4 is not yet been approved as a standard it is in cycle one year ahead of NFPA 72. It will be voted on before NFPA 72 technical committees second draft meetings. It is easier to put in the reference now and make adjustments later than it would be to do the opposite.

A.21.1 Fire alarm systems, signaling systems, and emergency communications systems are often part of a large, integrated system serving a building or area. Figure A.21.1 shows examples of individual systems that might be part of an integrated system. A fire alarm system might monitor the status of one of the other individual systems or provide a form of output to control another individual system, such as a smoke control system or an elevator controller. In some cases, the fire alarm system shares information and control in two directions with another individual system. NFPA 72 covers only the fire alarm or signaling system in the circuits powered by it, not any part of the other individual systems. See NFPA 4, Standard for Integrated Fire Protection and Life Safety System Testing, for additional information on integrated systems.

Supplemental Information File Name A.23.6.1_for_FR_237.docx Description Updated annex text Submitter Full Name: Lee Richardson Organization: National Fire Protection Assoc Submittal Date: Mon Nov 18 14:48:19 EST 2013 The change was made to migrate away from a maximum of 50-devices to limiting the loss of devices to one zone because 50-devices is not appropriate for all applications. The annex material gives additional guidance on how to approach the zoning of the system during the design stage. Annex A material is also revised - see attached.
A.23.6.1 The intent of 23.6.1 applies to both short-circuit faults and open-circuit faults. Fire alarm and signaling system communications technologies have evolved to the point that SLCs are now the prevalent means of monitoring initiation devices, controlling output devices, and communicating between panels, annunciators, and controllers. The extent of coverage of traditional IDCs is inherently limited based on the quantity of powered initiation devices or code limitations. Similarly, the extent and coverage of NACs also are limited by the power required to operate the devices. SLCs, unlike IDCs and NACs, have few limitations, and it is now common that a single SLC can monitor and control more than 250 devices. In addition, a single SLC can be the only pathway by which alarms are initiated, emergency control functions are controlled, and audible and visual notification appliances are activated. A total catastrophic failure of a fire alarm and life safety system due to a single open or short on an SLC can negate most, if not all, of this Code s requirements for specifying an acceptable minimum level of performance and reliability for the protection of life and property from fire. Designers should carefully consider the potential that a single SLC short or open caused by a fire or inadvertent damage to the SLC could disable an entire SLC prior to the activation of an alarm condition along with the subsequent alarm signaling and emergency control functions. With traditional IDCs and NACs, a single open, ground, or short fault on one circuit could not affect the performance of other IDCs, NACs, and emergency control circuits. As such, the occurrence of a single short or open limited the extent of the failure to a particular zone or area. One method for providing an acceptable level of performance and reliability of SLCs is to limit the potential catastrophic failure to one zone, in a way similar to how traditional IDCs and NACs have been and are now required to do. A single zone could be designated in the following ways: (1) By floor where an SLC would not span multiple floors (2) By floor area, where a large floor would be split into multiple zones based on a maximum floor area size (e.g., 22,500 ft 2 ) (3) By fire barrier or smoke barrier compartment boundaries, which an SLC would not cross (4) By maximum length or circuit, where an SLC would not be longer than a predetermined length (e.g., 300 ft) See the definition of zone (3.3.320) for additional clarification.

A.23.6.1.5 Possible scenarios in which a designer might choose to permit loss of more than one zone include a multistory building with a small floor plan footprint where a limited number of addressable devices are located on the floor (e.g., one manual fire alarm box and two automatic fire detection devices). In this scenario, the designer might choose to include multiple floors of devices on the same signaling line circuit because the loss of such devices due to a single SLC short or open would disable a limited number of devices. Another scenario could include buildings with a small vestibule at the top of a stair that exits onto the roof of a building. The vestibule might contain one manual fire alarm box and one or two automatic fire detection devices that could be connected to the signaling line circuit on the floor below and considered the same zone. Designers providing documents for upgrades to an existing building where the control units and all fire alarm system devices are being replaced but some portion of the existing circuits are being reused might, because of constructability reasons, opt for combining zones and the associated risk of the loss of those devices due to a single SLC short or open. The intent of 23.6.1.5 is not to impose an unnecessary burden on building owners with existing systems undergoing renovations, upgrades, or replacements. In these scenarios as well as others, the designer would be required to provide a documented, performance based design approach to justify why the loss of more than one zone is acceptable. Documentation must be composed in accordance with 23.6.2.2 and be submitted in accordance with 7.3.7.4.

Actuation of alarm notification appliances or emergency voice communications, emergency control function interface devices, and annunciation at the protected premises shall occur within 10 seconds after the activation of an initiating device.

The related annex material is also deleted - see attached. The following text is suggested for 10.11 and A.10.11: 10.11 * Actuation Time. Actuation of alarm notification appliances or emergency voice communications, emergency control function interface devices, and signal annunciation at the protected premises fire alarm control unit and other designated locations shall occur within 10 seconds after the activation of an initiating device. A.10.11 Other locations could include the following: (1) Building fire command center for in-building fire emergency voice/alarm communications systems (2) Fire alarm control unit for network fire alarm systems Actuation of an initiating device is usually the instant at which a complete digital signal is achieved at the device, such as a contact closure. For smoke detectors or other automatic initiating devices, which can involve signal processing and analysis of the signature of fire phenomena, actuation means the instant when the signal analysis requirements are completed by the device or fire alarm control unit software. A separate fire alarm control unit contemplates a network of fire alarm control units forming a single large system as defined in Section 23.8. For some analog initiating devices, actuation is the moment that the fire alarm control unit interprets that the signal from an initiating device has exceeded the alarm threshold programmed into the fire alarm control unit. For smoke detectors working on a system with alarm verification, where the verification function is performed in the fire alarm control unit, the moment of actuation of smoke detectors is sometimes determined by the fire alarm control unit. It is not the intent of this paragraph to dictate the time frame for the local fire safety devices to complete their function, such as fan wind-down time, door closure time, or elevator travel time.
