Xtralis VLF-500 VESDA System

Fire Projects has successfully installed various VESDA VLF-500 system, which is a very early warning smoke detector designed to protect small, business-critical environments of less than 500 m2 (5000 sq. ft.)

The detector works by continually drawing air into sampling holes in a pipe network. The air is filtered and passed into a detection chamber where light scattering technology detects the presence of very small amounts of smoke.Detector status information is communicated on the detector display and via relays or optional interface cards.
The patent-pending Ultrasonic Flow Sensing used in the VLF provides a direct reading of the sampling pipe flow rate. The system is immune to air temperature and pressure changes and is unaffected by contamination. The VLF is the first air sampling smoke detector to use ultrasonic flow sensing.
