FIELD: automatic fire-fighting equipment including aerosol generators with electric triggers. SUBSTANCE: trigger device includes one transistor, two tiristors, namely trigger and auxiliary tiristors, photon-coupled tiristor VU, three diodes, one light-emitting diode, four resistors and one socket connector. All above components are connected in accordance with described scheme. EFFECT: possibility of automatic control of aerosol generator trigger circuit serviceability, provision of sound alarm generation in the case of trigger circuit failure, prevention of short circuit as the reason of "welding" wires inside aerosol generator due to high temperature effect during generator charge combustion. 3 dwg
