These detectors are self-resetting and offer an 85dB alarm horn. An external push button provides a test of the detectors’ alarm function. Up to 12 units can be interconnected so that if one detector alarms, all detectors alarm. A normally open auxiliary alarm relay is available for controlling external functions. A visible LED indicator flashes once every 40 seconds in standby and rapidly in alarm when detecting smoke. The detectors offer low-voltage operation and a tamper-proof feature. Screw terminals and a mounting bracket are provided for easy installation.
