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.

38 of 1374 6/30/2016 11:10 AM Public Input No. 720-NFPA 72-2016 [ Global Input ] As applicable in the body of the code as well as any related annexes, all references to NFPA 70, The National Electrical Code, should be made to the entire document instead of a specific article unless technically required. Referencing a specific article in the NEC can lead to confusion and potential enforcement issues. For example many times only Article 760 is referenced leading some to believe that is the only part of the NEC that applies and not following or acknowledging the charging requirements established in Article 90-.

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.

There are integration and human interfaces that the building operators and designers are expecting. First responders are embracing new technologies and the fire life safety industry needs to do so all well without affecting reliability and performance. This public input is the first step in taking the fire life safety system into the technology flow. It defines the PC Workstation as the interface with the complete building technology.

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 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) * 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 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) * Performance alternatives approved by the authority having jurisdiction 12.4.5 Pathway Continuity. Where a 2-hour level of circuit protection is otherwise required and it is not possible to maintain a compete 2-hour level of protection due to the limitations of listed components, such as a junction box or communication device located within a 1-hour rated elevator lobby, the provisions of 12.4.5.1 shall be permitted. 12.4.5.1 Level 1 shall be permitted where there are at least two pathways that are separated by at least one-third the maximum diagonal of the area or floor the circuit is passing through and the pathway is Class X or Class N. There are cases and have always been cases where the requirement of 2-hour circuit protection is not possible to achieve without changing the otherwise rated construction required by the building codes. Examples, which have been brought to the attention of the committees in the past, include area of refuge communications and fireman phones that are located within an elevator lobby or area of refuge space. The listing of CI cable and the like are limited to the cable, not the 4-square junction box with an RCA jack and wall plate, or the plastic intercom or phone set. As such, the 2-hour circuit protection is lost at every such point. Thus, it is not feasible to maintain a 2-hour circuit unless you build a 2-hour rating around the jack or device. i.e. The building code would require a 1-hour level of protection. In order to comply with NFPA 72 every elevator lobby, area of refuge, or such would be required to be upgraded to a 2-hour enclosure. Such extensive rating and cost impact should not be dictated by a fire alarm code. Instead, the fire alarm code should take into account traditional fire rated construction practices used for decades and recognize protective features within its own code such as Class X. Option (4) allows performance-based alternatives. However, when we know that a system does not work in many cases as outlined in A.12.4.3(4), why should each designer and installer have to prepare performance alternatives. The proposed change allows the code to work as it should without the added time and expense of preparing alternatives already

Ethernet is an ubiquitous technology installed in almost every commercial building being designed today. Class N was introduced in 2016 edition, with an intention to create opportunities for developing Ethernet based technologies for Emergency Communication Systems; including the potential for Ethernet deployment of initiating devices and notification appliances. Yet, Class N is not necessarily Ethernet. Class N is a collection of performance criteria that could be achieved without necessarily utilizing Ethernet. However, it is impossible not to be aware of how thoroughly Ethernet and the technologies that utilize it have impacted almost all areas of modern life. Similar to telephone and television, Ethernet as a collection of technologies is global, and continues to proliferate; due primarily to the standard based approach to its design and deployment. Chapter 15 seeks to recognize the ongoing importance of Ethernet in delivering information, including all types of communication (visual, textual, & audible), and collecting real time information from sensors and people, and based on this information, providing system control from virtually anywhere. We may predict with confidence that Emergency Communication Systems technology will progress in all these areas. It is therefore reasonable to predict, with the introduction of Class N, Ethernet networks will play more prominent roles as a Life Safety Network. As such, Chapter 15 is intended to represent a place in this code where conditions of satisfaction for Life Safety Networks that are specific to Ethernet may be presented. There are other standards groups that have already collected a great deal of best practice information relating to the design and implementation of Ethernet networks, but they are not currently accounted for by this document, and are not recognized as requirements. And there may be instances where other standards do not go far enough to ensure the reliability of the Life Safety Network for Emergency Communication uses. Chapter 15 seeks to establish a framework to address this important area of technological progress for Emergency Communications Systems. Related Public Inputs for This Document
