FIRE ALARM DEVICE Russian patent published in 2022 - IPC G08B17/00 G08B25/10 A62C3/02 

FIELD: fire protection.

SUBSTANCE: invention relates to the field of fire prevention in case of ignition over large areas, namely to devices for transmitting fire signals over long distances, and can be used to detect a fire source on industrial sites and in remote areas. A fire alarm device containing a vertical cylindrical housing made of fireproof material with a head fairing and tail is proposed. A radio signal transmitter is located inside the housing in its head part. The housing is loosely fixed to the starting device with the help of rings in the form of a straight metal rod, the lower end of which is pointed. Additionally, inside the housing there is a temperature and radiation sensor, a gas concentration sensor, a battery, a cylinder with compressed non-flammable gas, at the outlet of which there is an electromagnetic valve, at the outlet of which there is a nozzle protruding outward from the bottom of the housing. At the same time, the temperature and radiation sensor, the gas concentration sensor, the electromagnetic valve, the radio signal transmitter are connected to the microcontroller, and the battery is connected to a solar cell attached to the outside of the housing to its head fairing.

EFFECT: reduction in the transmission time of the fire signal and an increase in the reliability of the signal transmission.
