The VESDA LaserFOCUS detector is a very early warning smoke detector designed to protect small, business-critical environments. The VLF-250 can protect areas up to 250 m2 (2500 sq. ft.) whilst the VLF-500 can protect areas up to 500 m2 (5000 sq. ft.)
The VLF 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 DialTM 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 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.
