Aspiration System are aspiration smoke detection used for early warning applications where response to a fire is critical.
Aspiration System works by continually drawing air into the pipe network via a high efficiency aspirator. A sample of this air is then passed through a dual stage filter.
The first stage removes dust and dirt from the air sample before it allows the sample to enter the laser detection chamber for smoke detection.
The second (ultra fine) stage provides an additional clean air supply to keep the detector’s optical surfaces free from contamination, ensuring stable calibration and long detector life.
