Wireless Smoke Detector

AW103SD

Wireless Addressable Optical Smoke Detector

This detector monitors the level of smoke in its surveillance and switches to alarm state when the live smoke value exceeds its pre-set threshold value.This detector with a unique ID communicates to the control panel by pin pointing its exact location. It is AA battery powered and provides Low Battery alerts to the control panel. This unit is mainly used at places where wiring is not feasible.

What is a smoke detector and how does it work?

Smoke detector is a measuring instrument that measures the level of smoke in its surveillance. It will raise an alarm only when the level of smoke exceeds its pre-set upper limit/threshold values.

Photoelectric/Optical Smoke detector work on a common light scattering principle. Smoke detector contains a chamber that consists of a light emitter usually a LED and a light a sensitive device like a photodiode that receives all the light directly emitted by the LED.

When the smoke enters the chamber, the intensity of light received by the photodiode reduces due to density of smoke. If the intensity of received light drops below a pre-set threshold level, fire alarm is triggered confirming fire. 

Unit of measure for level of smoke is Obscuration/foot (Obs/ft).

Photoelectric smoke detectors are highly sensitive to visual particles of smoke and also respond quickly to smouldering fires.

Wireless smoke detectors function on AA battery. They can communicate remotely with the control panel utilising its transmitter receiver section.
