Annunciation: responders need to know where, in a place they can reach

Annunciation: responders need to know where, in a place they can reach

The fire alarm control unit or a remote annunciator is located where the AHJ approves — typically the main responder entrance — and it identifies the zone or device that initiated the signal in plain language or on a graphic that can be understood without the installer present. Zones are arranged so responders can find the fire quickly: zone boundaries line up with floors and smoke compartments, labels are permanent, and a zone map is posted where the building code or AHJ requires. A text display that reads 'LOOP2 DEV147' helps no one in turnout gear.

NFPA 72 reference

Chapter 10 — Fundamentals

10.18 Annunciation and Annunciation Zoning (10.18.1 location approved by the AHJ; 10.18.2 annunciation of the condition and location; 10.18.3 zoning arranged for responder identification; labelling permanent)

References use NFPA 72 2019/2022 numbering — section numbers can shift between editions, so confirm in the edition your AHJ has adopted.

On the job

An AHJ walks through a new office tower and sees 'ADDR 2-034 SMOKE' on the annunciator. He asks where that is; nobody knows without the device schedule. Custom labels are programmed — '3RD FLR NE CORRIDOR SMOKE' — and a laminated zone map goes next to the annunciator at the fire department entry.
