This product is photoelectric type, and works on the principle that infrared scatters in the smoke to probe the smoke which is generated by both the incomplete combustion and combustion at the initial stage of the fire. The detecting chamber adopts special structure design and signal processing identification technology. It fits for indoor enviroment such as family use and public place.
