Optical Smoke Alarm. 12V-24V with Alkaline Battery Back-up. Interconnectable. Built-in 1A Relay 

The Ei186 Optical Smoke Alarm runs on a 12V to 24V DC power, and has a 9V Alkaline battery back-up. The alarm gives a fire warning when adequate smoke enters the chamber.

The alarm is supplied with an easi-fit base that allows quick and simple installation of the smoke alarm head. The easi-fit base automatically connects both the mains power and battery as the alarm slides on.

The alarm has a pair of built-in Volt free relay contacts (i.e. can be used to switch into a burglar panel).

The Ei186 Optical Smoke Alarm has other advanced features such as built-in circuitry to aid suppression of voltage transients and RF interference to further reduce the chances of false alarms under such conditions.
