VESDA VLF-500 Laser Focus Aspirating Smoke Detector Owner
INTRODUCTION
The VESDA VLF-500 detector 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.
Out-of-the-box operation
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 fi re service company, ensuring that service technicians arrive
onsite fully prepared.
Ultrasonic Flow Sensing
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.
