Listings/Approvals VESDA HLIs are recommended for monitoring only. They are not approved for use as a primary reporting device. Information available using the Open Protocol HLI Open Protocol High Level Interface The Xtralis 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-to-peer. VHX-0310 Open Protocol HLI (master-slave) In the master-slave model, the host supervises the communications link between itself and the HLI (slave) by regularly polling the HLI to determine whether there has been a change in the status of a detector on VESDAnet. In response to polling by the host, the HLI generates a single response which is sent back to the host. In this way, no unsolicited messages are sent from the HLI to the host. Depending on the polling strategy adopted, the Master/ 6ODYH2SHQ3URWRFRO+/,LVDEOHWRUHSRUWDQ\DQGDOO¿UHDODUPVZLWKLQDIHZ seconds of a detector going into alarm. Exact performance is dependent on the polling strategy adopted. 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. • Detector Type (VLC, VLS, VLP, VLF). • Alarm status (Alert, Action, Fire1 & Fire2). • Fault Status (System, Zone, Urgent, Power, Network, Flow, Filter). • Status (Isolated, Normalizing, AutoLearn, Scanning). • Display info (Alarm thresholds, Location name). • Display update (Smoke level, Alarm & Fault status). • Fault details (list of active fault codes). • Fault strings (ASCII strings to describe each fault code). • Detector controls (Reset, Isolate, Silence, Test, Scan or Normalize2). • &RQ¿JXUDWLRQRI'D\1LJKWDODUP thresholds2 In the peer-to-peer model, the host can request and receive multiple messages from the HLI. 1 VESDAnet is a propriety communications protocol allowing your VESDA range of smoke detectors, displays, programmers and remote units (collectively known as devices) to communicate with each other on the one network. VESDAnet is a fault tolerant bi-directional protocol. This means that if one direction of communication fails, then your VESDAnet messages are transmitted in the opposite direction.
