Optical smoke detector features and sepcifications:
· Features:
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
