Abstract
Actuation circuitry causes emergency energization of a vehicle fire and explosion detection and suppression system when the vehicle is not in operation. The actuation circuitry includes a simple fire and/or explosion detector which draws a small amount of power relative to that required by the main fire and explosion detection and suppression system when operative. When the detector detects an event which may be a fire or explosion the actuation circuitry activates the main system which analyzes the event by its more sophisticated circuitry and acts accordingly. When such event is no longer detected by the detector of the actuation circuitry, the main system is shut down.
