AW103SD
Wireless Addressable Smoke Detector
The primary purpose of the AW103SD wireless addressable Smoke Detector is to detect the presence of smoke within its surveillance area. Once the smoke reaches the alarm threshold level, it promptly triggers an alarm signal to the fire panel. This wireless device communicates with the control panel at a frequency of 433.92 MHz. The unit is powered by a built-in AA battery. When the battery power is low, it communicates with the control panel to alert for replacement. This unit is primarily used in situations where wiring is not feasible.
Highlighted features of this multisensor include:
- Ultra-sensitivity: It possesses an exceptional level of smoke sensitivity, enabling it to trigger early warning alarms.
- Discrimination of dust contamination: The detector can distinguish between dust contamination on the sensor chamber and the presence of actual smoke. This feature helps eliminate false alarms caused by contamination.
- Ultra smoke sensitivity
- Automatic drift compensation
- Corrosion protection
- bi-colour LED to indicate healthy and alarm condition.
- Dual LED for 360 deg viewing.
- Low battery warning
Storage temperature : -10ºC to 60ºC
What is a smoke detector and how does it work?
A 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 detectors work on a common light scattering principle. A smoke detector contains a chamber that consists of a light emitter usually a LED and a light-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 the density of smoke. If the intensity of received light drops below a pre-set threshold level, the fire alarm is triggered confirming fire.
The unit of measure for the level of smoke is Obscuration/foot (Obs/ft).
Photoelectric smoke detectors are highly sensitive to visual particles of smoke and also respond quickly to smoldering fires.
Wireless smoke detectors function on AA batteries. They can communicate remotely with the control panel utilizing its transmitter-receiver section.
