FIELD: fire safety.
SUBSTANCE: invention relates to firefighting equipment. Module of gas-powder volume fire extinguishing comprises means for storage of powder and device for storage of propellant, gas-powder flow forming facility, gas flow switch with control module connected to it, one of data inputs of which is intended for connection to fire alarm devices. Device for storage of powder is cylinder, which is connected to corresponding output of switch of gas flow by means of supplying pipeline. On one of pipeline sections there is pressure sensor connected to corresponding data input of control module. Cylinder stop-start device is connected to corresponding control output of control module, and via pipeline is connected with appropriate input of gas flow switch. Apparatus for generating gas-powder flow consists of nozzle by means of tube communicates with mixing chamber equipped with nozzles, nozzles are arranged inside flow splitter and sprayer.
EFFECT: technical result consists in increased distance to fire source and control of flow parameters of gas powder mixture in conditions of continuous operation of module.
