9V battery electric standalone independent smoke alarm detector China supply
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
