SUBSTANCE: generator of fire-extinguishing aerosol contains pyrotechnical stick with ignition assembly, installed on bottom of one of two dish-shaped casing tanks coated from inside with the functional layer out of solidified material, that are opposite connected by flangings, creating output slot nozzle, at that the functional layer of the top tank is enclosed by the perforated shell, and above the open end of the stick a receiver is formed, it via the reverse ring channel is connected with output slot nozzle. According to the invention the reverse ring channel between the perforated shell and open part of the pyrotechnical stick is connected with the output slot nozzle and is limited by the end of the functional layer adjacent to the bottom tank flanging, that closes gap between the bottom tank and stick. The suggested technical solution determined automatic two-stage action of the generator during serial modes: initially intensive burning of the pyrotechnical stick over the developed open surface, with high delivery of the extinguishing liquid, and then slow make-up of the additional aerosol until achievement of the extinguishing concentration.

EFFECT: as result of the stage supply of the generated aerosol intensity of filling of the protected object reduced, resulting in abrupt decreasing of its losses via slits, clearances, plays in the room, and ensured long-term inhibition of the fire extinguishing.
