SPRINKLER AIR FIRE EXTINGUISHING UNIT CONTROL METHOD AND DEVICE Russian patent published in 2018 - IPC A62C35/11 B05B12/00 B05B1/26 

FIELD: fire safety.

SUBSTANCE: invention relates to the field of sprinkler air fire extinguishing installations, which characteristic features are filled with water in standby mode supply pipes, absence of water in the extinguishing agent supply and distribution pipelines and maintenance of the pneumatic pressure therein. Sprinkler air fire extinguishing system control method includes the fire detection, the logical processing of information on the sprinklers status included into the sprinkler fire extinguishing unit equipped with actuation control device and the signal valve activation. In the fire extinguishing installation supply and distribution pipelines in standby mode, there is no air overpressure. Signal for the installation activation is generated by the activated sprinkler equipped with actuation control device. Sprinkler air fire extinguishing system contains signal valve, filled with water at operating pressure supply line, and sprinkler spraying nozzles. In the fire extinguishing installation supply and distribution pipelines there is no air overpressure. Unit is equipped with sprinklers equipped with actuation control device and deluge alarm valve. Deluge signal valve trigger element is connected to the each sprinkler spraying nozzle actuation monitoring devices contact groups.

EFFECT: technical result of the group of the invention is increase in the sprinkler air installation response due to use of the deluge signal valve, simplification of the design, reducing the installation operating time and enabling its use in rooms with a negative ambient temperature.
