Technical content

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. 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.
