Four Pipes Scanning Aspirating Smoke Detector VDOT- ASD-400-16

The Velocity Aspiration Detection uses high power, short wavelength blue LED as the detection light source. It is very sensitive to small smoke particles generated during the incipient stage of a fire, at which time can still remain invisible to the human eye.

The highest alarm sensitivity of the aspiration detectors is 0.005%/m, which is 1000 times more sensitive than a conventional point type smoke detector.

There is a choice of 2 detectors, covering either small areas (up to 1,000 sqm) or Large areas (up to 2,000 sqm) allowing you the flexibility dependent on your application needs
