An aircraft fire protection system includes a plurality of extinguishant bottles which can be detonated to deliver extinguishant into a manifold and then to selected fire zones through valves associated with the respective fire zones. Solid state control circuitry opens the appropriate valve when a corresponding push button switch is initially depressed and detonates one or more bottles in sequence when the same switch is subsequently depressed one or more times. A manual crash switch opens all valves when depressed once and discharges all bottles when depressed again. An automatic crash switch opens all valves and detonates all bottles if the aircraft should crash. A test circuit operates in a test mode to open all valves in sequence and to simulate sequential detonation of all bottles by applying low level current to the bottle detonator circuits.

A fire protection system for a vehicle such as on aircraft presenting therein a plurality of fire zones, said system comprising: a plurality of closed containers each holding extinguishant; a manifold connected with each container to receive extinguishant therefrom; an extinguishant line for each fire zone, each line having one end communicating with said manifold and an opposite end communicating with the corresponding fire zone to apply extinguishant thereto; a valve for each extinguishant line having an open position wherein the corresponding extinguishant line is open between said manifold and the corresponding fire zone and a closed position wherein the corresponding extinguishant line is closed; means for discharging each container to apply the extinguishant therein to said manifold; valve control means for each valve operable to move same from the closed position to the open position; and means for inhibiting said discharging means to prevent any container from being opened unless at least one valve is in the open position, whereby at least one valve is open whenever extinguishant is discharged from any container to the manifold.
