Ionization Vs Photoelectric Smoke Detector - StaySafeDiary
WebPhotoelectric smoke detectors are less common, but they are often used in commercial and industrial settings. They work by shining a light into the detection chamber. When smoke … WebThere are generally two types of smoke alarms - ionization smoke alarms and photoelectric smoke alarms. All fires produce smoke particles in varying number and size. Ionization … WebPhotoelectric. A photoelectric smoke alarm uses a light-sensitive sensor and an LED light to detect smoke. The smoke detector’s light sensor can’t pick up the LED light that’s emitted unless there’s smoke in the air, which causes the light to reflect and be picked up by the device’s sensor, triggering an alarm.
