HEAT FIRE DETECTOR BY MISEVICH Russian patent published in 2011 - IPC G08B17/00 

FIELD: fire safety.

SUBSTANCE: heat fire detector by Misevich, which comprises a light-emitting diode indicator, a transistor and a diode, a transistor switch and two capacitors, five resistors, a current-limiting element and two input terminals, differing by the fact that it comprises an additional stabilitron, the transistor performs the function of a heat sensor, and the current-limiting element performs the function of a thermally independent current stabiliser. In the proposed heat fire detector by Misevich, due to the transistor usage as a heat sensor, the detector actuation temperature stability is ensured even under high vibration conditions.

EFFECT: simplified setting of the detector actuation temperature by a simple ratio of resistor resistances, elimination of vibration effect at the actuation temperature.
