The VESDA Wall-Mounted 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’. With a built-in VESDAnet interface you don’t need a remote VESDAnet socket module, which makes the Wall-mounted HLI a cost effective solution to your interface requirements. There are two models available, depending on whether you require communication between your host and VESDAnet to be master-slave or peer-to-peer.
