System Smoke Detectors - Notification Devices
www.systemsensor.comWhen smoke particles partially block the light beam (Figure 9), the reduction in light reaching the photosensitive device alters its output. The change in output is sensed by the detector’s circuitry, and when the threshold is crossed, an alarm is initiated. Obscuration type detectors are usually of the projected beam type where the light source
