It’s critical
A fire detection system that offers the earliest possible warning of a potential fire. A system that will ensure business continuity and freedom from nuisance alarms. A system that can adapt to the ‘unique’ characteristics of any given environment. One that delivers high performance through its high quality design and its dedicated global sales and distribution channels.
With over 100,000 units installed worldwide, the VESDA name has become synonymous with high performance very early warning smoke detection. It is the product chosen when reliable performance is crucial.
VESDA….When Performance Counts.

This diagram shows progression of fire growth over time. Note that the incipient stage of a fire provides the widest window of opportunity to detect and control the spread of fire. VESDA can be configured to generate multiple alarms within the incipient stage. VESDA can also be configured to generate and additional alarm (Alarm 2) in the advance stages of fire. This feature is unique to VESDA and takes advantage of its' very wide sensitivity range; thus allowing one detector to monitor the entire progression of fire growth.

How VESDA Works
VESDA works by continually drawing air into the pipe network via a high efficiency aspirator. A sample of this air is then passed through a dual stage filter. The first stage removes the dust and dirt from the air sample before it allows the sample to enter the laser detection chamber for smoke detection. The second, (ultra fine) stage, has the unique feature of providing and additional clean air supply to keep the optical surfaces within the detector clear from contamination and to ensure the stable calibration and long life of the detector.
From the filter, the air sample is passed through to the calibrated detection chamber where it is exposed to a stable controlled laser light source. When smoke is present, light is scattered within the detection chamber and is instantly identified by the highly sensitive receiver system. The signal is then processed and presented via a bar graph display, alarm threshold indicators, and/or graphic display. The VESDA detectors are able to communicate this information to a fire alarm control panel, a software management system, or a building management system via relays or a High Level Interface (HLI).
