Palladium Optical Smoke Detector

An optical smoke detector or photo-electric alarm works on the light scattering principle. The sensor chamber checks for smoke particles after every 10 seconds with the help of a pulsed infrared LED beam. These smoke detectors indicate a fire in non-smoking zones. They are used widely by commercial and industrial buildings as a safety measure.

A commercial smoke detector sends a signal to the fire control panel while household fire alarms give audible or visual alarm from the detector.
