Vesda VHX-1420

Vesda VHX-1420 Metal Box HLI Modbus Type 3

The VESDA Modbus Type 3 High Level Interface (HLI) integrates VESDAnet network with host monitoring platforms such as Building Management Systems (BMSs) and Fire Alarm Control Panels (FACPs). The Modbus Type 3 HLI acts as a proxy for all VESDA devices on the VESDAnet network, providing access to the rich status information that is available from VESDA detectors as well as the ability to control and configure these devices. Alarms are reported 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 Modbus Type 3 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.
