VESDA Smoke Detection Systems

VESDA Smoke Detection

The acronym VESDA stands for Very Early Smoke Detection Apparatus and is used to describe an advanced aspirating smoke detection system that utilises laser technology to analyse the quality of air samples.

A network of aspirating pipes with multiple holes are strategically distributed throughout protected areas of the facility and connect to VESDA detector units. The detectors constantly draw air through the pipes and into the detector unit. Upon entering the VESDA detector unit's chamber, the air samples have any contaminants and dust filtered, before being subjected to the smoke detection laser within the chamber. If the laser bean is scattered due to smoke particles being present in the sample of air, the VESDA system alarm is triggered and signals sent to the central fire monitoring stations. This can often be before smoke is even visible to the human eye.
