Smoke alarm sensor, Smoke Detector Introductions:

Optical smoke detector is under BSI approval, and can be calibrated into either UL, VDS, NF Standards. This smoke detector features UL-approved Photoelectric sensing components with precise smoke detection. and long life (18 months) 9V battery operation (9V UltralifeLithium battery model for 10-year life is available too). 9V battery operated smoke detector, Meets CE, RoHS and EN14604

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
