Grill The Fire Expert Fire Alarm Rules for the Notification of Occupants
NFPA 5000 Requirements
Q: What are the fire alarm rules for the notification of occupants required by NFPA 5000?
A: Remember, no publication (even if it uses the word "Code" as part of its title) is enforceable by a building or fire official unless it has officially been adopted into law. Only then, is it truly a "Code." The 2003 edition of NFPA 5000, Building Construction and Safety Code, lists the following fire alarm notification requirements:
220.127.116.11 Unless otherwise provided in 18.104.22.168.1 through 22.214.171.124.4, notification signals for occupants to evacuate shall be by audible and visible signals in accordance with NFPA 72 and ICC/ANSI A117.1, American National Standard for Accessible and Usable Buildings and Facilities, or other means of notification acceptable to the authority having jurisdiction. (See: 126.96.36.199.1, 188.8.131.52.2, 184.108.40.206.3, 220.127.116.11.4)
18.104.22.168 The general evacuation alarm signal shall operate in accordance with one of the methods prescribed by 22.214.171.124.1 through 126.96.36.199.4. (See: 188.8.131.52.1, 184.108.40.206.2, 220.127.116.11.3, 18.104.22.168.4, 22.214.171.124.5 5, 126.96.36.199.6)
Of special note, where total evacuation of occupants is impractical due to building configuration, only the occupants in the affected zones shall be initially notified, and provisions shall be made to selectively notify occupants in other zones to afford orderly evacuation of the entire building.
Where occupants are incapable of evacuating themselves because of age, physical or mental disabilities, or physical restraint, the following shall apply:
(1) The private operating mode as described in Chapter 4 of NFPA 72 shall be permitted to be used.
(2) Only the attendants and other personnel required to evacuate occupants from a zone, area, floor, or building shall be required to be notified.
(3) Notification of personnel as specified in 188.8.131.52.3(2) shall include means to readily identify the zone, area, floor, or building in need of evacuation.
In mall buildings complying with Chapter 27, notification within the covered mall shall be permitted in accordance with 184.108.40.206.3.1.
220.127.116.11 Audible alarm notification appliances shall be of such character and so distributed as to be effectively heard above the average ambient sound level occurring under normal conditions of occupancy.
18.104.22.168 Audible alarm notification appliances shall produce signals that are distinctive from audible signals used for other purposes in the same building.
22.214.171.124 Automatically transmitted or live voice evacuation or relocation instructions to occupants shall be permitted and shall be in accordance with NFPA 72.
126.96.36.199 Unless otherwise permitted by another section of this Code, audible and visible fire alarm notification appliances shall comply with either 188.8.131.52.1 or 184.108.40.206.2.
220.127.116.11.1 Audible and visible fire alarm notification appliances shall be used only for fire alarm system or other emergency purposes.
18.104.22.168.2 Voice communication systems shall be permitted to be used for other purposes, subject to the approval of the authority having jurisdiction (AHJ), if the fire alarm system takes precedence over all other signals.
22.214.171.124 Alarm notification signals shall take precedence over all other signals.
