Alarm Smoke Detectors

Photoelectric sensor technology is the most common form of smoke detector for a security alarm system. Photoelectric alarm system smoke detectors contain a light source and a light-sensitive electric cell. Smoke particles in the detector deflect the light onto the photoelectric cell, thus generating a current and triggering the alarm. Optical smoke detectors more quickly detect slow burning, smoky fires. Heat detectors are a device that detects the heat from a fire and sounds an alarm or triggers a water sprinkler system. Heat detectors do not detect smoke and will not meet fire codes that require a smoke alarm. Most smoke detectors for secuirty alarm systems use combined both types of sensors.
