Because VESDA has the industry’s widest sensitivity range and multi-level warnings, even minute levels of smoke can be detected before a fire has time to escalate. How VESDA works. VESDA works by continually drawing air into the pipe network via a high efficiency aspirator. A sample of this air is then passed through a dual stage filter.
The Conventional VESDA-E VEU series of aspirating smoke detectors are the premium detector of the VESDA-E range. The VEU offers an ultra-wide sensitivity range, 15 times greater than the VESDA VLP, and provision for more sampling holes provide an increased coverage in high airflow applications by at least 40%. Considerably longer pipe runs and extended branched pipe network configurations allow the VEU to fit perfectly in to high ceiling and large open space areas while still allowing the detector to be mounted in an easily servicable location.Built on the revolutionary Flair detection chamber technology, which uses a CMOS imager for direct imaging of particles in addition to multiple photo-diodes, the Conventional VESDA-E VEU provides unsurpassed detection performance in addition to best in class flexibility, field programmability and connectivity.
