Aspiration Detection

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
