Vesda smoke detection systems offer the earliest possible warning of a potential fire. These highly-sensitive systems will ensure business continuity and freedom from nuisance alarms. These sophisticated devices can adapt to the unique characteristics of your process environment, to provide the most technologically advanced early warning fire detection methods available.

VESDA High-Sensitivity Smoke Detection
Vesda smoke detectors, by Xtralis, deliver impeccable performance for critical applications that demand the tightest measure of fire safety. With countless 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.
Xtralis revolutionized very early warning smoke detection with VESDA aspirating smoke detection (ASD) technology. As the pioneer of ASD with more than 25 years of experience, Xtralis has established a reputation for reliably protecting life, property and business continuity without compromise.
KFPI’s VESDA fire safety solutions deliver:
- Very early smoke detection to mitigate risk of catastrophic loss and business disruption
- Absolute calibration for superior smoke detector performance without compromise
- Reliable, continuous and highly sensitive operation where traditional smoke detection fails
- Full integrity monitoring of all critical smoke detector functions to ensure the detector is able to detect smoke, unlike conventional smoke detectors
- Tolerance of harsh and dirty environments
- Event management tools for intelligent emergency response
- The industry’s lowest total cost of ownership

What is Very Early Warning Smoke Detection?
VESDA aspirating smoke detection solutions with continuous air sampling provide the earliest possible warning of an impending fire hazard. VESDA aspirating smoke detectors buy the critical time needed to investigate an alarm and initiate an appropriate response to prevent injury, property damage or business disruption. VESDA detectors have multi-level warnings and a wide range of sensitivity that does not degrade or change over time, so even minute levels of smoke can be detected before a fire has time to escalate. In addition, VESDA HSSD (High Sensitivity Smoke Detection) systems are manufactured using targeted Six Sigma techniques and ISO 9000 standards and have been certified by regulatory bodies worldwide.
VESDA aspirating smoke detection 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 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 an 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).
