PHOTOELECTRIC SMOKE ALARM IS FAR MORE SENSITIVE AND EFFECTIVE THAN IONIZATION SMOKE ALARM

  • How does Photoelectric Smoke alarm works?

  1. Inside the smoke alarm, there is a LED light that sends a beam of light (similar to a laser pointer) in a separate compartment inside the chamber, there is a photosensor that detects light.
  2. As smoke enters the detector, the smoke particles interrupt the light beam, scattering it in many directions. Some of the LED light scatters toward the light sensor. When light beams hit the sensor, the alarm will go off!
  3. When the batteries in your smoke alarm get low, the smoke alarm automatically activates a low battery chirping sound different from the alarm sound so you know it's time to get new batteries.

  • Photoelectric sensors are set off when smoke enters the alarm and deflects the light of an LED beam onto a photocell.
  • For slow, smoky, smoldering fires, photoelectric alarms are far more sensitive and effective.
  • Choose a photoelectric model as our primary choice, killing the fire at the begining.
