Photoelectric Sensor
Photoelectric smoke detectors are designed to detect the presence of smoke in a room by using a light beam. When smoke enters the detection chamber, it scatters the light, which triggers the alarm. These detectors are especially useful for detecting smoldering fires that can fill a room with smoke quickly. Smoldering fires typically produce smaller flames that are less visible, making them more difficult to detect with traditional smoke detectors.
By using a photoelectric smoke detector in conjunction with a traditional ionization smoke detector, you can provide comprehensive protection against both types of fires. They use both ionization and photoelectric technology to provide a comprehensive and reliable detection system. Ionization detectors are designed to detect flames, while photoelectric detectors are designed to detect smoke. By using both types of detectors in one device, dual detectors provide a more complete and accurate detection system.
