Differences Between Photoelectric Smoke Detectors and Ionization Smoke Detectors
Among the different types of smoke detectors available, two common choices are photoelectric smoke detectors and ionization smoke detectors. Understanding the differences between these two types can help homeowners make an informed decision about the best option for their needs. In this article, we will explore the principle of operation, sensitivity, false alarm rates, and safety aspects of both types. Principle of Operation Photoelectric smoke detectors Photoelectric smoke detectors use a light-sensitive mechanism to detect smoke. Within the detector, an infrared light beam is projected into a sensing chamber. When smoke particles pass through the chamber, they scatter the light beam, triggering the alarm. Ionization smoke detectors ionization smoke detectors employ a small amount of radioactive material to generate charged...
