4.2 Operation Principle
The smoke detector detects fire by scatting of infracted beam. A pair of diodes of infrared transmitter and
receiver is installed within the black body, and they can hardly receive any signal under smoke-free environment,
but when fire occurs, the smoke will enter the detector chamber and scatter the light, which can send a weak
signal to the infrared transmitter, and the signal then will be amplified by 200-400 times by the amplifying circuit.
The threshold valve of this amplified signal will be judged by the trigger circuit, if it reaches the threshold of a fire
alarm, the LED indicator for fire will be lit and remains on, at the same time, the fire info will be sent to the fire
alarm control panel to generate a fire alarm.
