FIRE-EXTINGUISHING SYSTEM Russian patent published in 1998 - IPC

FIELD: used in fire-extinguishing in stationary rooms, on all types of transport facilities and in any other closed space. SUBSTANCE: system consists of several interconnected fire-extinguishing devices each of which has temperature-sensitive element which serves simultaneously both as device for detection of fire and device for initiation of fire extinguishing; aerosol-forming explosive compound, electric fuse and pyrotechnic current generator. In case of presence of several fire-extinguishing devices, pyrotechnic current generator is connected via electric circuit with all electric fuses of other devices. Sensor of temperature-sensitive element is made mainly of low-melting material or material with shape memory. EFFECT: higher reliability in detection and extinguishing of fire of solid, liquid combustibles at initial stages of fire in stationary rooms, on all types of vehicles and any other confined spaced. 2 cl, 1 dwg
