ABSTRACT:
A fire and explosion suppression system which is operative for suppressing an explosion within 100 milliseconds of the existence of a high energy ignition and within 200 milliseconds of the existence of a low energy ignition. Respective output signals from a detector of ultraviolet radiation and a detector of infrared radiation are fed to a logical AND circuit to provide a third output signal indicative of simultaneous receipt of ultraviolet and infrared radiations. Actuation apparatus responsive to the third output signal then actuates extinguishing agent distribution apparatus for discharging an extinguishing agent into the volume to be protected, such as the troop compartment and/or the engine compartment of an armored vehicle.
