A fire extinguishing system for vehicles homes and offices includes a firing assembly for attachment to a container of fire extinguishing agent, a firing pin for penetrating the container to release the fire extinguishing agent, the firing pin being moved by an explosive squib or a solenoid, a conduit for carrying fire extinguishing agent to a discharge outlet, and a control system having a capacitor for pulse discharge of electric power to the control head to fire the squib or solenoid. 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.
