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. Actuation circuitry for this system is also disclosed and claimed and includes circuitry operative in two different modes having different sensitivities and response as well as circuitry for sensing the failure of suppression elements to operate and for actuation of additional suppression elements in response to this sensed failure.
