METHOD FOR AUTOMATIC FIRE HAZARD CONTROL AND AUTONOMOUS FIRE TRIGGER DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC A62C37/00 A62C37/08 A62C37/50 

FIELD: fire hazard automatic control.

SUBSTANCE: invention relates to method for automatic control of fire hazard and an autonomous fire alarm and trigger device that are designed to detect the thermal factor of a fire and for the subsequent launch of an automatic fire extinguishing agent. Device contains a source of autonomous power supply and an electrical connection made in the form of two parallel electrical circuits, where one circuit contains a thermal sensor made with normally open contacts that close when the temperature of the controlled environment reaches a value corresponding to the temperature characteristic of a fire, and another circuit, which performs the function of testing the device operability, contains a series-connected test button made with normally open contacts, a resistor that limits the current at a safe level for the actuator, and an indication LED, moreover, the parallel connection of two circuits with one common end through an autonomous power supply source is connected to the first terminal of the two-terminal connector, while the second connection terminal is connected to the other common end of the parallel connection of two circuits, the two-terminal connector is configured to be connected to the actuator.

EFFECT: said invention provides detection of the thermal factor of a fire and subsequently launches an automatic fire extinguishing agent.
