The VDOT-ASD-100 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 VDOT-ASD-100 high sensitivity smoke detector is 0.005%/m, which is 1000 times more sensitive to conventional point type smoke detector.
