VESDA Systems

What is 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 recognized 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  qsystems 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. The benefits and details of which can be viewed via the drop-down list above.
