Abstract

A pressure responsive and pressure operative device which includes an intrinsically safe detonation circuitry particularly designed for the suppression of explosive situation where the initial indication of a developing explosion and subsequent fire is an increase in pressure within a protected volume which is normally related to a building or other structure. The device includes a directed housing serving as a cannon which holds an extinguishant containing canister which incorporates an explosive charge for producing a rapidly rising pressure within the canister for substantially instantaneous discharge of extinguishant from the canister and instantaneous release of propelling fluid pressure from a pressure supply tank for additional extinguishant propulsion. The unit is operative with only low voltage and pressure thus making the same intrinsically safe.
