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.
