Types of Smoke Detectors and Their Differences

2020-11-13· Unlike ionization detectors, these detectors use a light source and a light sensor to detect smoke. Once the smoke enters the detection chamber, the smoke particles block the light beam and partially reflect light onto the sensors. This in turn trips the alarm. Since many smoldering fires fill the room with dangerous fumes and smoke way before progressing to the open-flame stage, these type …
