SAS Intelligent Aspirating Smoke Detection system (ASD) is an ultra-sensitive, highly effective, aspirating smoke detector which provides Very Early Warning type smoke detection in diverse applications ranging from mission critical to harsh environments.
Our ASD use a pipe network and a fan to draw air from a protected space in to the detection chamber. This pipe network allows for smoke detection in hard-to-reach or difficult-to-access areas, including areas with temperature extremes, and allows for ease of testing and maintenance.
The sampling chamber is based on a nephelometry that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber. This system can typically detect smoke before it is visible to the naked eye.
