Now discontinued, the VESDA VLP/VLC detectors paved the way for aspirating smoke detection to evolve from a niche technology to a mainstay of the fire prevention industry.

Features include;

  • Absolute smoke detection (coverage of 800 m2 or 8,000 sq. ft)
  • Wide sensitivity range (0.005 - 20% obscuration/m and 0.0015 - 6% obscuration/ft)
  • Single pipe inlet
  • Five (5) status LEDs
  • Clean air barrier optics protection
  • Three (3) alarm levels
  • Three (3) programmable relays
  • Air flow monitoring

Step 1

The service interval of an air filter depends upon the environment. You can use the LCD Programmer or VESDA PC Software guides to change the service interval for filters. The system will generate a minor fault when the filter has reached 80% and an urgent fault when it reaches 120% of its capacity. We recommend that the installation date and replacement date are written on the air filter cartridge label as a physical reminder of when the next service is expected.

Important Note:
The detector must have the power turned on when the air filter cartridge is being replaced.
