VESDA Aspirating Smoke Detection


VESDA® VLI by Xtralis®
The VESDA VLI by Xtralis is an industry first early warning aspirating smoke detection (ASD) system, designed to protect industrial applications and harsh environments of up to 2000 m2 (21,520 sq. ft.). 
Long life, intelligent, fail-safe technology
The VLI detector combines a fail-safe Intelligent Filter (patent pending) with an advanced clean-air barrier for optics protection allowing the use of absolute detection and a long detection chamber life without the need for re-calibration.
The Intelligent Filter:
-reduces the level of pollution in the air sample before it enters the detection chamber, which dramatically extends the operational life of the detector in harsh and polluted environments.
-is fully monitored, providing consistent sensitivity over the entire operational life of the detector.
