Virtual Network Tunnel

Installation Instructions
Model VNT

INTRODUCTION

The Model VNT Virtual Network Tunnel (as shown in Figure 1) from Siemens Industry,
Inc. is a UL approved fanless single board computer that is powered from its local
24V power supply with battery back up. The VNT Gateway is responsible for support-
ing the intercommunication of system components.
It transports HNET and XNET supervision and
monitoring between VNTs via TCP/IP. It also routes
audio over TCP/IP when required between VNTs. If
the VNT Gateway is at a control point, it is respon-
sible for generating audio from the local source.

The VNT Gateway utilizes some or all of the
following interfaces depending upon its location
within the system:

100BaseT TCP/IP connection to a local Fiber Ring Switch. This connection
transports the network signals (HNET and XNET), audio, supervision and
monitoring data streams.

One or more independent HNET RS485 interfaces to the module network of an
XLS/Desigo Fire Safety Modular/Cerberus PRO Modular or its components.

An XNET RS485 interface to the XLS/Desigo Fire Safety Modular/Cerberus
PRO Modular node(s) within a given system.

An XNET over TCP/IP feed to an NCC at a command center.

An HNET RS485 interface to an XLS/Desigo Fire Safety Modular/Cerberus
PRO Modular node within a given system.

An audio input to accept a microphone paging source.

An audio output to distribute paging audio to a given system.

INSTALLATION

The VNT mounts on a VNT-MP in a CAB1, CAB2 or CAB3 enclosure. Refer to the VNT-MP
Installation Instructions, P/N 315-050489, for information on mounting the VNT-MP.

Remove all system power before installation, first battery then AC. (To power up,

connect the AC first, then the battery.)
