Vesda VLF-500 LaserFOCUS Detector – 500m2 Coverage

The VESDA LaserFOCUS detector delivers the most advanced air sampling smoke detection technology to small environments – cost effectively. The VLF-500 model protects areas up to 500 sq.m. In addition to the features found in all VESDA Laser products, the VESDA LaserFOCUS provides a new range of features & built-in intelligence that allow quick installation, commissioning and servicing.

The detector works by continually drawing air into sample 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 VESDA LaserFOCUS can be installed and commissioned out-of-the-box without the need for a special interface or software programming tools.

In operation, the unique Smoke Dial display provides the user with an instant understanding of a smoke event, even from a distance. Should a fault occur, the user simply opens the field service door and activates the Instant Fault Finder feature to determine the specific fault condition. This information can then be passed onto their fire service company, ensuring that service technicians arrive onsite fully prepared. The patent-pending Ultrasonic Flow Sensing used in the LaserFOCUS 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. VESDA is the first air sampling smoke detector to use ultrasonic flow sensing.
