VESDA VLI Relay only


Approval: G 212155

The VESDA VLI is an early warning aspirating smoke detection (ASD) system, designed to protect industrial applications and harsh environments of up to 2000 m2.
The VLI detector combines a fail-safe intelligent filter (patent pending) with an advanced clean-air barrier for optics protection allowing the use of absolute detection and a long detection chamber life without the need for re-calibration.

The intelligent filter:
• reduces the level of pollution in the air sample before it enters the detection chamber, which dramatically extends the operational life of the detector in harsh and polluted environments.
• is fully monitored, providing consistent sensitivity over the entire operational life of the detector.

  • Suitable for Class 1 Division 2 applications
    - Groups A,B,C & D
  • Up to 4 inlet pipes
  • Five high intensity status LEDs for greater visibility
  • Robust absolute smoke detection
  • Intelligent Filter (patent pending)
  • Lint Trap to capture fibrous particulates
  • Secondary filter
  • Clean air barrier for optics protection
  • AutoLearn™ Smoke and Flow
  • Clean Air Zero™
  • Air-path monitoring
  • Five relays (Fire, Fault and 3 configurable)
  • Ultrasonic flow sensing
