The Xtralis VESDA VLI-880 is the VESDA VLI (Laser Industrial) aspirating smoke detector, an early warning ASD system designed to protect industrial applications and harsh environments of up to 2,000 m².
It combines a fail-safe, fully monitored Intelligent Filter with a clean-air barrier for optics protection, giving absolute detection and a long chamber life without re-calibration. The VLI is supported by Xtralis ASPIRE, VSC and VSM4 software and is compatible with existing VESDA installations. (The VLI-885 variant adds VESDAnet.)
Key features
