BCAB #1464 - Fire Alarm Annunciator Design, Sentence 184.108.40.206.(1)
April 14, 1998
Re: Fire Alarm Annunciator Design, Sentence 220.127.116.11.(1)
This project involves the installation of an annunciator panel with an LCD display panel instead of LEDs or lamps.
Reason for Appeal
Where an annunciator is required, Sentence 18.104.22.168.(1) requires it to have "separate zone indicators."
The appellant is installing an addressable fire alarm system and a conventional lamp style annunciator panel would defeat the purpose of having an addressable system. The appellant contends that the LCD panel conforms to the requirements of the code.
Building Official's Position
The building official maintains that separate indicators are required for each zone. An LCD panel which must be manipulated to determine what signals are being received from the fire alarm system is not acceptable. There is no objection to an addressable system but the basic zone indicators cannot be left out without compromising the effectiveness of the fire alarm system.
Appeal Board Decision #1464
It is the determination of the Board that Sentence 22.214.171.124.(1) requires an annunciator panel with separate or individual indicators for each zone. This precludes the use of an indicator, such as a small LCD screen, which can only display a few zones at a time.
