Optical Beam Detection
 
 

Optical Beam Smoke Detectors work by using a projected beam of light to detect smoke in large areas. They are generally used in larger buildings where the size or height of a room would make standard smoke detectors an uneconomical alternative. If a certain percentage of light is blocked or absorbed by smoke an alarm is triggered to warn the buildings occupants that there is a fire.

Optical Beam Detection systems offer wider coverage at minimal cost compared to other fire detection methods, making it the perfect solution for commercial and industrial buildings where large spaces need to be monitored.

 
How It Works

The Optical Beam Smoke Detector works by detecting light obscuration using a Transmitter and a Receiver. A Transmitter and Receiver are installed at opposite ends of the room, up to 100m apart and the Receiver is connected to a control unit.

The Transmitter projects a beam of light across the room towards the Receiver. If the Receiver detects obscuration in the light, caused by obstruction or absorption from smoke, a signal is sent to the control unit which calculates the density of the smoke based on the level of obscuration and signals an alarm in accordance to pre-set sensitivity constraints.
