designed to respond to a broad range of fires while providing maximum stability. This

model also features low-voltage wiring making it ideal for applications such as apart-

ment buildings and nursing homes.

Features.

The System Sensor 2012H photoelectronic detector is designed prima-

rily for applications where low-voltage Class 2 wiring may be used. This detec-

tor is non-latching and offers an 85dB alarm horn. The 2012H features the

NFPA72 required audible emergency evacuation signal referred to as temporal

(3) tone. An external push button provides a test of the detector's alarm func-

tion. Up to 12 units can be interconnected so that if one detector alarms, all

detectors alarm. A normally open auxiliary alarm relay with an 8 second delay

is available for controlling external functions. A visible LED indicator flashes

once every 30 seconds in standby and rapidly (every 0.5 seconds) in alarm

when detecting smoke. The detector offers low-voltage operation and a tamper-

proof feature. Screw terminals and a mounting bracket are provided for easy

installation.
