FIRE-EXTINGUISHING SPRINKLER PLANT AND METHOD OF OPERATION OF SAID PLANT Russian patent published in 2018 - IPC A62C35/00 

FIELD: fire safety.

SUBSTANCE: sprinkler fire-extinguishing plant contains a distribution network with controlled sprinkler water mist sprayers with, that are connected with their autonomous blocks of multifactor control and management with the possibility of each block to perform its multicriterial early fire detection and low-inertia forced start of its sprinkler sprayer by a pyrotechnic drive. The distribution network is complete with an autonomous function and is connected via a supply pipeline and a check valve with an electric pump connected to a water feeder tank, which is connected to a drinking and household water pipeline via a float valve, and the electric pump is controlled by a power control unit coupled with a control and automation control device, designed to control the electric pump switching on by a pressure sensor signal for an operating time, set by the device program in order to form a mist water jet with a specified spraying time.

EFFECT: early detection of fire, low-inertia start of fire-extinguishing means, fire extinguishing by a small volume of water at facilities that have a drinking and household pipeline as the only source of water.
