Best price battery operated Standalone photoelectric smoke detector

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
