VESDA Laser Focus Aspirating Smoke Detector (VLF) VLF-250
The VESDA VLF-250 detector is a very early warning smoke detector designed to protect small, business-critical environments of less than 250 m2 (2,690 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.
