Vesda Laser Smoke Detection System

OnDuty Systems, LP Commercial Fire Systems Department

VESDA (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.

“Our latest installation of the Vesda System was for the Houston Zoo in a critical environment.  We are excited to be certified and authorized as a Houston contractor for this new fire detection technology”, says Greg Martin, OnDuty System’s general manager.

An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke.

The sampling chamber detects the presence of smoke particles suspended in air by detecting the light scattered by them in a chamber using laser light.   ASDs can typically detect smoke before it is visible to the naked eye.

In most cases aspirating smoke detectors require a fan unit to draw in a sample of air from the protected area through its network of pipes.
