o Works on principle that infrared scatters on smoke surface

o Probes smoke which is generated by incomplete combustion at initial stage of fire

o Smoke detector consists of photoelectric system, signal processing identification and alarm circuit

o Infrared scatters on surface of smoke when smoke enters darkroom of detector

o Photoelectric diode receives scattered light and generates photoelectric signal current

o Photoelectric signal generates alarm signal after being processed by identification circuit, accordingly purpose of alarming is achieved
