High sensitivity
The ASD features extremely high sensitivity and wide sensitivity adjustment range
(0.005%–20% obs/m). It can detect both potential fire in the early phase and particles
released by the softened insulation layer of an overloaded power cable.
Precise detection result
The ASD works in active air sampling mode. The efficient aspirator continuously sends
air samples from the protected area to the detection chamber for analysis. The detection
result and response time are less influenced by air flow compared with a traditional fire
detection method.
Flexible installation
The ASD detection unit is compact and easy to install. The air sampling pipes can be
deployed depending on site requirements. The air sampling pipes are made of PVC and
can be installed on or under the ceiling, under the floor, at air return vents of smart
cooling products, and in locations that need special protection. For example, the
sampling capillaries can be installed in a cabinet to monitor equipment in the cabinet.
Convenient maintenance
The ASD is equipped with a special filter that filters air for cleaning the laser measuring
chamber. The filter can be easily maintained and replaced, and cleaned by blowing air
into the air sampling pipes. Therefore, you do not have to replace any other components.
Efficient auto-diagnosis system
The ASD is designed with an efficient auto-diagnosis system for monitoring the working
status of itself, the network, and the air sampling pipes in real time. If a fault is detected,
the system generates an alarm and indicates the fault location for troubleshooting.
