HEAT FIRE DETECTOR Russian patent published in 2010 - IPC G08B17/06 

FIELD: fire safety.

SUBSTANCE: heat fire detector comprises microcontroller, output signal generator, element of single-sided conductivity, limiter of current and voltage, two capacitors, two input terminals, and also resistor and light diode, comprises additional second resistor and other connections between elements so that light diode performs function of reference voltage generator. In proposed heat fire detector due to application of additional resistor, microcontroller with analogue inputs and other connections between elements, when light diode performs function of reference voltage generator.

EFFECT: reduced error of detector.
