Operation principle：During the electric starter operation of the extinguishing device of the utility model design, when temperature is not up to predetermined
During value, because temperature sensor RT resistance is more than 1/2 (Rp+R1), 2. pin current potential is higher than 1/3G (2V) to IC1 triggering end, makes
The 3. pin for obtaining IC1 is low potential, and diode VD cut-offs, IC2 is because cannot get supply voltage and no audio signal output, loudspeaker B
It is noiseless.When temperature is increased to predetermined value, RT resistance will be less than 1/2 (Rp+R1), and 2. pin current potential is less than 1/ to IC1 triggering end
3. pin is that low potential jumps to high level, diode VD conductings, output about 5V (200mA) direct current to 3G (2V), IC1 output end
Voltage.The DC voltage supplies IC2 after electric capacity C2 filtering.At this moment siren signal caused by IC2 is exported by OUT terminal, through C3 couplings
It is bonded to IC3 input 3. pin progress power amplification.Audio signal after amplification exports from IC3 5. pin, most afterwards through electric capacity C6
