The smoke detector works on the principle that infrared scatters in the smoke to probe the smoke which is

generated by the incomplete combustion at the initial stage of the re. It consists of photoelectric system,

signal processing identication circuit and alarm circuit. The infrared scatters on the surface of the smoke

when the smoke enters the darkroom of the detector, then the photoelectric diode receives the scattered

light and generates the photoelectric signal current. The photoelectric signal generates the alarm signal

after being processed by the identication circuit, and the alarm is set off. The product HS-103 has a

small, modern and unique design, and is of convenient to use.
