The FDK series photoelectric smoke detector detect combustion products (smoke) generated by a fire, and transmit an alarm signal to the fire alarm control panel. The photoelectric smoke detector can detect a fire in an earlier stage than a heat detector. Generally, this detector is installed in the spaces such as basements, ordinary floors, corridors, staircases, elevator shafts.

The photoelectric smoke detector is composed of a light source, light sensing element, light shielding element and detecting chamber. The light source (a light-emitting diode) emits light at intervals of about 3.5 seconds, which does not reach the light sensing element (photo diode) under nomal conditions because of the light shielding mold. If smoke enters the detecting champer, the light from the light source is scattered by smoke particles and reches the light sensing element. The light reaching the light sensing element varies with smoke density and if it exceeds the predetermined level, the detectors operates and automatically holds its operation. The detector then transmits the alarm signal to the fire alarm panel and the response lamp of the detector turms on
