Vesda VHX-0320

Vesda Xtralis VHX-0320 PC Link HLI Access Protocol

The VESDA Access High Level Interface (HLI) integrates VESDAnet networks with host monitoring platforms such as Building Management Systems (BMSs) and Fire Alarm Control Panels (FACPs). The Access HLI acts as a proxy for all VESDA devices on the VESDAnet network, providing access to the rich status information available from VESDA detectors as well as the ability to control and configure these devices.

The Access HLI is able to report alarms to the host within a few seconds of a detector reaching an alarm condition. Exact performance is dependent on the polling strategy and size of the monitored network. The Access HLI is able to support up to 100 VESDA detectors on a single VESDAnet network. A standard unit used to provide a flexible solution where permanent mounting is not required. In this case a VESDAnet socket interface is required to connect the HLI onto the VESDAnet network.
