Detailed Product Description

The smoke detector works on the principle that infrared scatters in the smoke toprobe the smoke which is generated by the incomplete combustion at the initial stageof the fire. It consists of photoelectric system, signal processing identificationcircuit and alarm circuit. The infrared scatters on the surface of the smokewhen the smoke enters the darkroom of the detector, then the photoelectricdiode receives the scattered light and generates the photoelectric signal current.The photoelectric signal generates the alarm signal after being processed bythe identification circuit, accordingly the purpose of alarming is achieved.
