2012JA Photoelectric Smoke Alarm with Integral Relay and Sounder

Compact, attractive, and easy to install, the System Sensor 2012JA smoke alarm 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 homes, apartment buildings and nursing homes.

The System Sensor 2012JA photoelectronic detector is designed for applications where low-voltage Class 2 wiring may be used. This smoke alarm is non-latching and offers an 85dB alarm horn and form C alarm contact. An external push button provides for testing of the units alarm function as well as silencing. Up to 12 units can be interconnected so that if one unit alarms, all units alarm. A form C alarm relay with an 8 second delay is included for monitoring or controlling external functions. Interconnected units can be wired so that the alarm relays activate on any alarm or individually. A visible LED indicator flashes once every 40 seconds in standby and rapidly in alarm when smoke is detected. On interconnected units, only the smoke alarm that detects smoke will flash, thus providing indentification of the alarm source. The detector offers low-voltage operation and a tamper-proof feature. Screw terminals and a mounting bracket are provided for easy installation. The 2012JA contains a microcontroller which constantly monitors the integrity of the smoke chamber and provides a trouble signal if the chamber tests fails.

The 2012JA is a highly reliable smoke alarm designed for residential and light commercials applications.
