Key Features

  • Direct access and monitoring of your entire VESDAnet system
  • Built-in VESDAnet Interface socket card (provides communication and power to the HLI)
  • Convenient wall-mounted design
  • Seamless data transfer on networks of up to 200 VESDA devices
  • Easily configured using Xtralis configuring and monitoring software packages


The VESDA Wall-Mounted High Level Interface (HLI) links VESDAnet with PC software monitoring and configuring tools such as Xtralis VSM4 and Xtralis VSC. The wall-mounted HLI includes a built-in VESDAnet socket card to provide seamless data transfer from your VESDAnet to your PC.

The wall-mounted HLI allows an entire VESDA network to be configured, managed and monitored by interfacing with PC monitoring and configuration tools via its built-in VESDA socket card. The built-in VESDAnet socket card also provides 24VDC to the HLI unit which means no additional power supply is required.

The VESDA Wall Mounted High Level Interface does not need to be mounted near a VESDA detector. Instead, it can be installed in an easily accessible, remote location away from your detectors such as on a wall near to your PC. It is easily configured using a PC with Xtralis VSC or Xtralis VSM4 software packages.
