Addressable
AVA CSD series products are specially designed for the detection of a single canbient or small room. When AVA CSD systems is in alarm, users can easily identify the fire location, solving the problem that typical aspirating detection systems can only provide large area warning but fails to pinpoint the exact location of the fire.
Very Early Warning
When ASD was fist introduced in the 1980s, the Xenon lamp was used as the light source taking advantage of the bright and full-spectrum light to achieve very high sensitivity smoke detection.
Aspirating Detection
Air samples and aerosols are drawn through a sampling pipe network with air sampling holes and carried to one or more smoke sensing elements by an integral aspirator. The air sampling pipes and holes are installed to where the smoke might appear when there is a fire.
Multi Sensors
AVA Detectors not only provide Very Early Warning Smoke Detection, additional information of the air samples like Temperature, Humidity and/or specific gas concenrtration like Carbon Monoxide can also be provided by optional sensor modules. 
Artificial Intelligence
False alarms are always a concern for ASD systems because of the high sensitivity.
