VESDA Aspirating Detection

Direction Fire Limited are designers and installers of the Vesda by Xtralis product with proven experience engineering aspirating systems for an extensive range of applications to meet specific risk requirements.

VESDA by Xtralis very early warning smoke detection solutions with continuous air sampling provide the earliest possible warning of an impending fire condition. VESDA detection can provide 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.

VESDA for Gas Detection and Environmental Monitoring

VESDA ECO uses an existing VESDA pipe network to actively monitor for gas leaks and continuously ensure air quality. VESDA ECO reliably detects unseen hazards by conditioning or filtering the air to remove moisture, dirt and other particulates.

Solutions are available for a wide range of gases – typical examples are carbon monoxide detection within car parks and hydrogen detection within battery rooms. Both these applications can be linked to extract fans/make up dampers to provide the necessary ventilation.
