FIELD: fire safety.
SUBSTANCE: thermal fire sensor with the fire extinguishing function includes a temperature sensitive element and a contact group of the fire alarm electrical circuit containing at least one movable contact. According to the invention, a temperature sensitive element is placed relative to the contacts providing normally closed or normally open circuit, is thermally-activated microcapsules of the extinguishing agent and is executed with enabling circuit switching in an opposite condition using rolling contact.
EFFECT: provides easy maintenance of the device, instantaneous initiation of the fire-fighting process with simultaneous notification of fire, use of a minimum amount of extinguishing agent, the possibility of reusing the device.
