Aspirating Smoke & Gas Detection

Aspirating smoke detection is a technology that utilizes a centralized detector that continuously draws air into the detector from a sampling pipe network located within the protected area. Whether your application is dusty, dirty, wet, highly-ventilated, or has extreme temperatures, vibrations, or electromagnetic interferences, aspirating smoke and gas detection may be the solution for your difficult smoke detection needs.

Very Early Warning Smoke Detection

VESDAI VLIVEWSD is a technology that provides the ability to detect a fire in its incipient phase so that it can be investigated and controlled before it escalates causing damage, loss of life or assets and adversely impacting business continuity. Active cumulative sampling, a wide dynamic sensitivity range and multiple alarm levels are fundamental advantages over conventional detection technologies and enables the deployment of ASD in a wide range of applications.


Industrial Fire Curve


Active Continuous Sampling

Unlike other detectors that rely on thermal lift and convection forces to cause smoke to enter their detection chamber, our aspirating smoke detectors are constantly drawing air into the detector. Air flow, detection chamber, and faults are continuously monitored on a 24/7 basis to ensure that the detector is ready to respond when needed.

Active Continuous Sampling Each sampling hole in the pipe network is considered representative of a single spot or point detector.


Wide Dynamic Sensitive Range

It is well known that ASD systems have higher sensitives than conventional point-type smoke detectors, but what is not commonly understood is the Wide Dynamic Sensitivity Range. This feature allows the operator in the field to either increase or decrease the detector's sensitivity to match the requirements of the application. This is one of several fundamental reasons why ASDs are effective in harsh and industrial environments.

Industrial WDR
Sensitivity and alarm thresholds for each detector are based upon the individual project, site requirements, and environmental conditions.


Multiple Alarm Thresholds

Unlike other detection technologies that have a single alarm threshold Aspirating Smoke Detectors have multiple alarm thresholds that provide valuable information regarding the escalation of a potential fire event. This provides time to investigate, identify, and control the threat during its incipient phase before it escalates - preventing business and process disruption, providing more time for evacuation, and protecting lives.
