Overview
What it is and how it fits the system.
The Sliding Windows model suits small or large networks, and this unit is the one aimed at the larger end, up to 200 devices. Data transfer runs from your VESDAnet to your PC, and the HLI is easily configured using your Xtralis VSC or Xtralis VSM4 software packages.
Connection is made to a VESDAnet socket card, which is how the interface reaches the smoke detectors, displays, programmers and remote units on the network. One limit governs where VHX-0200 may be applied: VESDA HLIs are recommended for monitoring only and are not approved for use as a primary reporting device.
Key features
- Sliding Windows Interface — VHX-0200 is the VESDA Sliding Windows High Level Interface, without modem capability.
- Up To 200 Devices — It is designed for large networks of up to 200 devices.
- Links VESDAnet To PC Tools — The HLI links your VESDAnet with PC software monitoring and configuring tools such as Xtralis VSM4 and Xtralis VSC.
- Fault Tolerant Protocol — VESDAnet is a fault tolerant bi-directional protocol, so if one direction of communication fails the messages are transmitted in the opposite direction.
- VESDAnet Socket Card Required — To configure and monitor devices on VESDAnet, your HLI must be connected to a VESDAnet socket card.
- Monitoring Only Limitation — VESDA HLIs are recommended for monitoring only and are not approved for use as a primary reporting device.
Technical overview
VHX-0200 is the VESDA Sliding Windows High Level Interface, a unit without modem capability that links your VESDAnet with PC software monitoring and configuring tools such as Xtralis VSM4 and Xtralis VSC. It is designed for large networks of up to 200 devices, and by interfacing with those PC tools the Sliding Windows HLI allows you to easily configure, manage and monitor your entire VESDA network.
VESDAnet itself 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. It is a fault tolerant bi-directional protocol, which means that if one direction of communication fails, then your VESDAnet messages are transmitted in the opposite direction. To configure and monitor devices on VESDAnet, your HLI must be connected to a VESDAnet socket card.
One limit applies to the role: VESDA HLIs are recommended for monitoring only, and they are not approved for use as a primary reporting device.
