VESDA Air Sampling Systems

VESDA is the abbreviation for Very Early Smoke Detection Apparatus. The VESDA Air Sampling system is, therefore, a highly sensitive smoke detection system. Such a system can detect fires long before the conventional smoke detectors would. These systems are usually installed in communication centres, computer rooms, switch rooms, data centres, clean rooms, and archive stores.

Being the most advanced equipment in the fire industry, VESDA is based on laser meaning that it is a very sensitive detector. They have been in operation for the past over 20 years and have received more certifications than any other smoke detecting equipment.

How It Works

The equipment draws in air through a network of pipes using a high efficacy aspirator. The air is then passed through a system of air sampling pipes. Inside each of these pipes, there is an airflow detector that senses any airflow changes. The air is passed through a chamber with laser detection. This serves to protect the optical faces within the detector from any kind of contamination.

Optimal positioning of the sensors and the use of stable Class one light sources ensures that the sensors achieve optimum results irrespective of the varying types of smokes. The external display system is meant to display any faults within the equipment. This means that all faults can easily be displayed on the screen using the VESDAnet, a fault-tolerant communication system.
