The control box includes a three-position switch for firing the system, putting the system on automatic function, or deactivating the system. Other switches can include sensors for activating the firing pin in response to high temperature, or vehicle impact. One or more optical flame sensors are employed with pulse counting electronic circuitry. Also included herein is an electropneumatic firing assembly employing a movable piston valve.
