Photoelectric Smoke Detectors Fire Safety The Home Depot Shop our selection of Photoelectric, Smoke Detectors in the Electrical Department at The Home Depot. What is a Photoelectric Smoke Detector? | Photoelectric ... Photoelectric Smoke Detectors. A photoelectric smoke detector is characterized by its use of light to detect fire. Inside the alarm, there’s a light sensing chamber. In this chamber, an LED light shoots a beam of light in a straight light across the chamber. The alarm detects smoke; when smoke enters the chamber,... The 8 Best Smoke Detectors of 2019 Photoelectric smoke alarms are best at detecting smoldering fires, while ionization smoke alarms are better at detecting sudden, fast burning fires. Experts say photoelectric smoke detectors generally won’t cause as many false alarms, but for the ultimate in safety, they recommend opting for a smoke detector with both types of sensors. : Photoelectric Smoke Detectors Smoke Detector Fire Alarm, 2 Packs Photoelectric Smoke Detectors with UL Listed, 9V Battery Operated Smoke Detector (9V Battery Included), 10 Years Life Time, Fire Safety for Home, Hotel, School etc 4.5 out of 5 stars 62 Photoelectric Detectors How Smoke Detectors Work ... Photoelectric smoke detectors therefore use light in a different way. Inside the smoke detector there is a light and a sensor, but they are positioned at 90 degree angles to one another, like this: In the normal case, the light from the light source on the left shoots straight across and misses the sensor. Ionization vs photoelectric nfpa.org Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”). How they work: Photoelectric type alarms aim a light source into a sensing chamber at an angle away from the sensor.
