Product Overview
12 VDC operation, 4-wire
Compact, attractive, and easy to install, the System Sensor 2012H detector is
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.
Built-in 85dB electronic horn with
temporal (3) tone
Built-in, normally open relay can be
connected to lights, bells, horns,
or remote annunciator
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.
