Vesda VHX-1320 Metal Box HLI Access Protocol

Vesda VHX-1320 Metal Box 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.

The wall-mounted version is housed in a metal enclosure allowing for permanent mounting on a flat surface. With a built-in VESDAnet interface you don’t need a remote VESDAnet socket module making the wall-mounted HLI a cost-effective solution to your interface requirements.
