Vesda VHX-0300 PC Link HLI Peer To Peer Complete with Leads (Open Protocol)

Vesda VHX-0300 PC Link HLI Peer To Peer Complete with Leads (Open Protocol)

The VESDA Open Protocol High Level Interface (HLI) links your VESDAnet1 with PC software monitoring tools, Building Management Systems (BMSs) and Fire Alarm Control Panels (FACPs), otherwise known as ‘host’. There are two models available, depending on whether you require communication between your host and VESDAnet to be master-slave or peer-topeer.

VHX-0300 Open Protocol HLI (Peer-to-Peer)

In the peer-to-peer model, the host polls the HLI for information about devices on VESDAnet, while the HLI sends unsolicited messages to the host. In this way, both the HLI and host are responsible for supervising the communications link between them. In the peer-to-peer model, the host can request and receive multiple messages from the HLI.
