VESDA Gateway

The VESDA Gateway provides a communication link between the Xtralis™ VESDAnet network, and the NOTI•FIRE•NET™ network (NFN) via the VHX-1420-HFS High Level Interface (HLI). The VESDA-HLI-GW translates VESDAnet protocol to NFN protocol, enabling events on the VESDAnet to be annunciated on compatible fire network annunciators. The VESDA-HLI-GW connects to the standard or high speed NOTI•FIRE•NET™ and enables event notification and control of VESDA detectors on the VESDAnet through a supervised HLI VHX-1420-HFS. Event notifications for up to 100 detectors are displayed on the fire network annunciators with a device type of “Aspiration.” Control can be initiated from these annunciators.

• Communicates with the VHX-1420-HFS using Modbus protocol via RS-232 connection.
• Supervises the communications to the VHX-1420-HFS.
• Monitors up to 100 detectors.
• Displays VESDA detectors as type “Aspiration” on the display nodes.
• Monitors VESDAnet detector events from NCA-2, LCD-160,
• ONYXWorks, and NFS2-3030 configured for Network Display Mode.
• Controls VESDAnet detector functions from NCA-2, ONYXWorks, or NFS2-3030 configured for Network Display Mode.
• Performs Read Status of VESDAnet detectors from NCA-2,
• LCD-160, ONYXWorks, and NFS2-3030 configured for Network Display Mode.
• Enables zone mapping.
• Provides DCC mode as required for Canadian applications.
• The VESDA-HLI-GW translates VESDAnet protocol to NFN
• protocol, enabling events on the VESDAnet to be annunciated on compatible fire network annunciators, including FACP.
