Photoelectric Smoke Detectors

Photoelectric smoke detectors use light sensors to detect fire. When smoke interrupts the light beam inside a photoelectric detector, the alarm is sounded.
Photoelectric smoke detectors identify the existence of slow, smoldering, smoky fires more quickly than other technologies, such as ionization.

OnlineSafetyDepot.com carries several types of photoelectric smoke detectors made by Kidde and other fire safety brands. Used together with ionization sensing detectors, which are better at recognizing fast flaming fires that produce little smoke, photoelectric alarms can make homes, businesses, and other places of occupancy safe from fire hazards.
