Vesda VHX-0420 PC Link HLI Modbus MK3

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. 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.

A VESDA High Level Interface (HLI) enables connection between a VESDAnet and configuration and monitoring platforms. Two main models are available:

1) Sliding Windows HLI, which enables communication between a VESDAnet and configuration and monitoring software packages Xtralis VSC and Xtralis VSM4 and

2) Open Protocol HLI, which integrates a VESDAnet to third-party software packages, building management systems (BMSs) and fire alarm control panels (FACPs).

These HLIs are available in a plastic portable housing, which can be used in multiple sites, and a fixed wall-mounted configuration to provide a permanent connection in a convenient location at one site.
