Photoelectric Smoke Alarms consist of a light emitting diode and a light sensitive sensor. The presence of suspended smoke particles in the chamber scatters the light, which is detected, setting off the alarm. Photoelectric technology is superior to ionisation technology in detecting the visible smoke produced by smouldering fires, which most commonly occur in homes.
