Chapters 1 through 4 The scope has been changed to: NFPA 72 covers the application, installation, location, performance, inspection, testing and maintenance of fire alarm systems, fire warning equipment, and emergency communication systems and their components. Emergency Communications Systems shall be classified as follows: In Building Emergency Communications Systems In Building Mass Notification Systems Wide Area Mass Notification Systems Distributed Recipient Mass Notification Systems Two Way Emergency Communication Systems In Chapter 3-Definitions, there are 74 new definitions Chapter 10 is now to be called Fundamentals Page 20
Chapters 10 New Fundamentals 10.15 Protection of Fire Alarm Systems The exception has been removed in 10.15. This allowed that there be no smoke or heat detector protecting the FACU or power supplies if the building was fully sprinklered. Detection is required in ALL conditions Record of Completion is completely revised to 12 pages 10.18.2.1.2.7 Completion Drawings, to be located at the main FACU or location identified at FACU, and storage cabinet must be labeled. Page 21
Chapters 10 New Fundamentals (cont.) 10.5.6.3.1(1) Added a requirement for battery calculations to include a 20% safety margin 10.4 Revised the section on qualifications (as per instructions from the TCC) Brought over a number of the requirements from Article 300 and 760 to Chapter 10 as extract material 10.6.1 Signal Priority, ECS signals when evaluated via risk analysis in Chapter 24 allows MNS to override fire Page 22

Chapter 17 Initiating Devices 17.4.6 Initiating devices shall be installed in all areas, compartments, or locations where required by other NFPA codes and standards or as required by other governing laws, codes, or standards This replaces AHJ, and has been added through the body of NFPA 72. Page 24
Chapter 17 Initiating Devices (cont.) Changes have been made to the criteria in 17.7.1.11 regarding protection during construction into 3 separate paragraphs as follows: "Protection during construction Where detectors are installed for signal initiation during construction, they shall be cleaned and verified to be operating in accordance with the listed sensitivity or replaced, prior to the final commissioning of the system. (17.7.1.11.1) Where detectors are installed but not operational during construction, they shall be protected from construction debris, dust, dirt and damage in accordance with the manufacturer's recommendations. (17.7.1.11.2) Where detection is not required during construction they shall not be installed until after all other construction trades have completed clean-up. (17.7.1.11.3) Page 25
Chapter 17 Initiating Devices (cont.) The TC adopted new language for section 17.7.3.2.3.1 that was the object of the TIA on the last edition [2007]. The new language: 17.7.3.2.3.1. "In the absence of specific performance-based design criteria, smoke detectors shall be located using a nominal 30 foot spacing." A. 17.7.3.2.3.1. "For the purposes of this section a "nominal 30 foot spacing" shall be deemed to be 30 feet +/- 5% (+/- 1.5 feet)." This language seemed to address the problem that "shall be permitted to be 30 feet" does not preclude any other distance yet instructs the AHJ to allow some latitude in the enforcement. Page 26
Chapter 17 Initiating Devices (cont.) 17.7.3.2 Spot-Type Smoke Detectors 17.7.3.2.1 Spot-type smoke detectors shall be located on the ceiling or, if on a sidewall, between the ceiling and 12 in. (300 mm) down from the ceiling to the top of the detector. The 4 inch restriction has been removed Page 27

72, 2010 Chapter 12 Pathway Interconnections 12.3 Pathway Class Designations Pathways shall be designated as Class A, B, C, D, E, or X, depending on their performance as follows: Class A*. A pathway with a redundant path. Operational capability continues past a single break. Conditions that affect the intended operation of the path are annunciated. Class B. A pathway without a redundant path. Operational capability stops at a break. Conditions that affect the intended operation of the path are annunciated. EOL Page 35
72, 2010 Chapter 12 Pathway Interconnections 12.3 Pathway Class Designations (cont.) Pathways shall be designated as Class A, B, C, D, E, or X, depending on their performance as follows: Class C. One or more pathways where operational capability is verified via end-to-end communication, but the integrity of individual paths is not monitored. A loss of end-to-end communication is annunciated. Class D. A pathway that has fail-safe operation, where no fault is annunciated, but the intended operation is performed instead. Class E. A pathway which is not monitored for integrity. Class X. A pathway with a redundant path. Operational capability continues past a single break or short-circuit. Conditions that affect the intended operation of the path are annunciated. Page 36
72, 2010 Chapter 13 Pathway Interconnections Now Chapter 12 Survivability has also been assigned "levels" in recognition that one size does not fit all. For example: 12.4.1 Pathway Survivability Level 0: Requires no provisions for survivability Pathway survivability Level 0 shall consist of the following: Pathways shall comply with the requirements of NFPA 70 Articles 760, 770 or 800 12.4.2 Pathway Survivability Level 1 Pathway survivability Level 1 shall consist of the following: Pathways in buildings fully protected by an automatic sprinkler system in accordance with NFPA 13, Standard for the Installation of Sprinkler Systems and with the interconnecting wiring or cables installed in metal raceways Page 37

Emergency Communications Systems Scope 24.2.1 The systems covered under Chapter 24 are for the protection of life by indicating the existence of an emergency situation and communicating information necessary to facilitate an appropriate response and action. 24.2.2 This chapter establishes minimum required levels of performance, reliability, and quality of installation for emergency communications systems but does not establish the only methods by which these requirements are to be achieved. Page 66
Emergency Communications Systems Key Areas Intended to communicate information about emergencies including but not limited to fire, terrorist activities, other dangerous situations, accidents, and natural disaster Requires intelligible voice messages Ancillary functions including the use of the system for general paging, background music and other non-emergency functions are permitted provided they don't interfere with emergency performance requirements.
