The VESDA VLF-500 detector is a very early warning smoke detector designed to protect small, business-critical environments of up to 500 m2.
The VLF can be installed and commissioned out-of-the-box without the need for a special interface or software programming tools. The patent-pending Ultrasonic Flow Sensing used in the VLF provides a direct reading of the sampling pipe fl ow 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.
