Model VNT
Virtual Network Tunnel
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 supporting 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 responsible 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.)
The following items are supplied with the VNT (P/N 500-650490):
| Quantity 1 | Item |
|---|---|
| 1 | VNT fanless computer |
| 1 | Cable P/N 555-150464 |
| 4 | Cable P/N 555-150494 (to fiber switch) |
| #8-32 hex nuts |
VNT Mounting
Refer to Figure 2.
The VNT mounts at the top of the VNT mounting plate with the four hex nuts
provided.
- Place the VNT over the four studs on the VNT-MP.
- Place the four hex nuts supplied over the studs and tighten them to secure the VNT to the VNT-MP.
WIRING
Wiring for the VNT-Building Configuration is shown in Figure 3. Wiring for
the VNT-Fire Command Center is shown in Figure 4.
All connections are supervised and power limited unless otherwise stated.

Cyber security disclaimer
Siemens products and solutions provide security functions to ensure the secure
operation of building comfort, fire safety, security management and physical
security systems. The security functions on these products and solutions are
important components of a comprehensive security concept.
It is, however, necessary to implement and maintain a comprehensive, state-of-
the-art security concept that is customized to individual security needs. Such
a security concept may result in additional site-specific preventive action to
ensure that the building comfort, fire safety, security management or physical
security system for your site are operated in a secure manner. These measures
may include, but are not limited to, separating networks, physically
protecting system components, user awareness programs, defense in depth, etc.
For additional information on building technology security and our offerings,
contact your Siemens sales or project department. We strongly recommend
customers to follow our security advisories, which provide information on the
latest security threats, patches and other mitigation measures.
