Virtual Network Tunnel

Installation Instructions

ModelVNT

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 overTCP/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:

• 100BaseTTCP/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 overTCP/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):

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 infor-

mation on the latest security threats, patches and other mitigation measures.
