VESDA

VESDA (an abbreviation of Very Early Smoke Detection Apparatus) is a laser based smoke detection system. The name VESDA has become a generic name for most air sampling applications. The name VESDA is a trade mark of Xtralis.

Having been operating within specialist fire detection applications for over 20 years, the VESDA system has a proven track record and has been developed beyond traditional fire alarms, to the point where it is recognised as the most advanced aspirating smoke detection system within the fire industry, holding more certifications than any other aspirating smoke detector in the world.

How does VESDA work?

A VESDA detector is much like a vacuum cleaner. It sucks air from the protected environment via purpose built aspirating pipe and fittings and samples the quality of air passing through the VESDA detection laser chamber.

Where can VESDA be used?

Simply, VESDA can be installed anywhere that a conventional smoke detector system can, but with greater flexibility.

Where conventional systems have to be strategically placed to provide maximum protection, our VESDA systems can be installed in easily accessible positions as the system is complimented by a network of our high grade ABS pipe work.

Additional benefits of using VESDA over conventional detectors are greater reliability and efficiency with features which include entire airflow analysis and ignition point targeting, with the ability to work alongside existing smoke detection and air conditioning systems symbiotically.

Our VESDA installations are in the widest variety of environments thanks to the ingenuity of the design, these including ceiling voids, cold rooms, computer rooms, and warehousing.

VESDA VLF
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 fire 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.

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.

The VESDA VLF-500 detector is a very early warning smoke detector designed to protect small, business-critical environments of less than 500 m2 (5,380 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.
