VDOT-ASD-100 Aspirating Smoke Detector User’s Manual V1
Introduction
VDOT-ASD-100 is aspirating smoke detectors
especially developed for small area very early
warning fire detection.
Most early warning fire detection products
were seeking very high sensitivity smoke
detection to protect a large area; while VDOT-
ASD-100 is aiming at protecting proper size of
area. In fact, because of the nature of the
aspirating smoke detection, the bigger the
detection area is the less sensitive the system
becomes. In order to provide very early
warning fire detection in a large area
application, the alarm threshold of the
detector must be set to very sensitive and is
closed to environment background smoke
level. This makes the system very easy to have
unwanted or false alarms.
The prefer detection zone size of VDOT-ASD-100 is only about one quarter to one half of that
of the popular product on market (typically 2000sqm); while it provides much better
performance of very early fire detection and better ability immune to false/unwanted
alarms.
Features
VDOT-ASD-100 uses high power, short wavelength blue LED as the detection light source. It
is very sensitivity to small smoke particles generated during the incipient stage of a fire, at
which time remaining invisible to human eyes. The highest alarm sensitivity of ASD high
sensitivity smoke detector is 0.005%/m, which is 1000 times more sensitive than a
conventional point type smoke detector.
