General Description
System Sensor 1012B ionization and 2012B photoelectronic
detectors are designed primarily for applications where
low-voltage Class 2 wiring may be used. 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.
