Page 12: How The Vli Works
www.acornfiresecurity.com VESDA VLI Product Guide VESDA by Xtralis How the VLI works The VLI detector continually samples air from the protected environment via a sampling pipe network (A). Upon entering the detector, the air passes four sets of ultrasonic flow sensors (B), then through the mixer compartment of the Intelligent Filter (C), where it is split between two pathways. - Page 13 www.acornfiresecurity.com VESDA by Xtralis VESDA VLI Product Guide 2.2.1 Clean Air Zero Clean Air Zero is a user-initiated feature which is primarily intended to safeguard against nuisance alarms. This is achieved by introducing clean air into the detection chamber and taking a reference reading. This reading is then offset against the actual environmental background to maintain consistent absolute smoke detection.
