Four Pipes Scanning Aspirating Smoke Detector VDOT- ASD-400 LDNDAMP1050X1250 The output relay is alwaysThe 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,
