How does a Smoke Detector Work?

Smoke detectors have a device that detects the presence of smoke and warns occupants by sounding an alarm. The most common type of smoke detector is the photoelectric smoke detector. The photoelectric smoke detector works by using an optical beam to search for smoke. An alarm is sounded when smoke particles cloud the beam. Even though each smoke detector is different from the next, they all are important in helping to keep the ones you love safe. Look here for more information:
