In buildings with aesthetic or architectural features—such as ornate ceilings or ceiling artwork—discreet, unobtrusive smoke detection is often required. In large open atria or voids, stratified thermal layers can prevent cooled smoke from reaching conventional detectors, meaning standard systems may only respond once significant fire damage has occurred.
VESDA aspirating smoke detection systems address this by using small-bore capillary pipes that sample air at specific locations while remaining largely invisible. Pipes can be hidden behind light fittings, integrated into ceiling artwork, or incorporated into architectural features, providing ‘invisible’ smoke detection. In tall, high-volume spaces such as cathedrals, sampling points can be positioned at intermediate vertical levels to overcome smoke stratification. The high sensitivity of VESDA detectors ensures early warning with minimal smoke.
With over 250,000 systems installed worldwide, VESDA is recognized for high quality and exceptional performance. Optimal performance depends on a well-designed pipework system, which led Xtralis, the manufacturer of VESDA detectors, to launch the VESDA Pipe and Fittings range in 1997.
