Professional factory for standalone independent electric smoke alarm
Main Functions:
Standalone surface mounted, easy operate
Stable performance, high sensitivity
Apply optical smoke test room
With buzzer, alarm independently
Simulate alarm test
Low voltage alarm when it less than 6.8V
Features:
Works on principle that infrared scatters on smoke surface
Probes smoke which is generated by incomplete combustion at initial stage of fire
Smoke detector consists of photoelectric system, signal processing identification and alarm circuit
Infrared scatters on surface of smoke when smoke enters darkroom of detector
Photoelectric diode receives scattered light and generates photoelectric signal current
Photoelectric signal generates alarm signal after being processed by identification circuit, accordingly purpose of alarming is achieved
