VESDA

VESDA air aspirating systems provide the earliest warning of a potential fire that buys time to investigate, intervene and potentially avoid business disruption, damage, downtime and cost of a
suppression system discharge. The multiple warning levels of a VESDA system can be used to trigger different responses at different stages of a fire, from controlling air conditioning to initiating a
suppression release.

VESDA systems works by continuously drawing air into a distributed pipe network via a high efficiency aspirator. The air sample then passes through a dual stage filter. The first stage removes dust and dirt from the air sample before it enters the laser detection chamber. When smoke is present, light is scattered within the detection chamber and instantly identified by the highly sensitive receiver system. VESDA systems are able to communicate this information to a house alarm fire panel, software management system, or a building management system via relays or high-level interface.

 

It is used alongside detection and suppression systems within a building to provide extra protection and also to detect small smoke particles much before a larger scale hazard is present. It is particularly useful within data centres or areas with high value equipment, where one small electrical issue can cause a much larger problem if not caught early.
