The LF-PE-6201 intelligent type photo-electric smoke detector utilizes the light scatter sensing principle. It has an infrared light source, which emits signals and photo-diode, which senses the scattering light with the effect of smoke entering the chamber. The chamber is of light proof labyrinth type protected with thin metals mesh for protection from dust, insects and other external interferences.
