Specifications/Special
Features:
Features:
1.Works on principle that infrared
scatters on smoke surface
2.Probes smoke which is generated
by incomplete combustion at initial stage of fire
3.Smoke detector consists of
photoelectric system, signal processing identification and alarm
circuit
4.Infrared scatters on surface of
smoke when smoke enters darkroom of detector
5.Photoelectric diode receives
scattered light and generates photoelectric signal current
6.Photoelectric signal generates
alarm signal after being processed by identification circuit,
accordingly purpose of alarming is achieved
