INSTALLATION INSTRUCTIONS
Model VN2001-A1 Ethernet Module (10/100 BaseTx)
The optional Model VN2001-A1 Ethernet Module (10/100 BaseTx) is an interface card which provides dual
interconnecting copper wire links for networked systems.
FEATURES
The principal features of the VN2001-A1 (10/100 BaseTx) include:
Is easily plugged into the host card or assembly
Is automatically identified by the system at power up
Protects the Ethernet signal path from overvoltage caused by electrostatic
discharge (ESD) or electrical fast transients (EFT)
Provides optimal ground fault detection (user selectable)
Provides Power-over-Ethernet (PoE), 24V, 500mA (user
selectable)
Can be used in the UL and ULC markets
PRE-INSTALLATION
1. Determine from the site-specific shop drawings whether the VN2001-A1 should be set for ground fault
supervision alone, Power-over-Ethernet (PoE) plus ground fault supervision, or neither function.
2. For ground fault supervision alone, set the jumpers as illustrated in Figure 2a. For Power-over
Ethernet plus ground fault supervision, set the jumpers as illustrated in Figure 2b. If neither ground
fault supervision nor PoE is required, set the jumpers to the default setting as illustrated in Figure 2c
a. Ground Fault Only b. Power-over-Ethernet and c. Open (default setting)

OPERATION
The VN2001-A1 Ethernet Module (10/100 BaseTx) can be used both in Voice networks of FV2025/2050
Fire Voice Control Panels and in generic Ethernet systems.
Operation in a Voice Network of FV2025/2050 Fire Voice Control Panels
The VN2001-A1 Ethernet Module (10/100 BaseTx) is an optional card that plugs into the VCC Card Cage to
provide an electrical interface for an Ethernet backbone network of FV2025/2050 Fire Voice Control Panels
(see Figure 3). Each link in a Backbone is independently of any other link. It can be implemented as either
copper wire or fiber-optic cable without any regard to what is used for the other links in the network.
NOTE: For installation instructions applicable to fiber-based links, see Siemens Industry, Inc., Building
Technologies Division, document number A6V10370419 Installation Instructions for the Model
VN2002-A1 Ethernet Module (MM) and the Model VN2003-A1 Ethernet Module (SM).
The backbone is a dual self-healing, redundant, ring network that is able to detect failures and then
automatically isolate and recover from them using an alternate routing.

Operation in a Generic Ethernet Network
In addition to its use in an Ethernet backbone network of FV2025/2050 Fire Voice Control Panels (as
illustrated in Figure 3), the VN2001-A1 Ethernet Module (10/100 BaseTx) can also be used to support copper
wire connections among standalone FN2012-A1 Ethernet Switches (modular).
Controls and Indicators
The two LEDs on the VN2001-A1 which are located at the copper cable connector indicate the following:
Green = Link established
Yellow = Signal activity

MOUNTING
Mounting the VN2001-A1 Ethernet Module, 10/100 BaseTx, in a Voice Network of FV2025/2050 Fire
Voice Control Panels
CAUTION: Power down the Voice Panel before mounting the VN2001-A1.
1. Open the middle door of the FV2025/2050 Fire Voice Control Panel.
2. Unscrew the latch on the front of the Card Cage and remove the Card Cage cover.
3. If a VCC2001-A1 Voice CPU is installed in card slot X202, remove it. If no VCC2001-A1 is
installed, proceed to the next step.
4. Referring to Figure 4, if the two knockouts for Ethernet modules are still present in the Card
Cage top panel, remove them. To avoid damage to sensitive electronic components, remove
any burrs that may be present in the knockout opening.
5. Install the VCC2001-A1 Voice CPU card into card slot X202 according to instructions provided in
Siemens Industry, Inc., Building Technologies Division, document number A6V10397772
Installation Instructions for the Model VCC2001-A1 Voice CPU Card..
Figure 4
Removing knockouts for Ethernet Modules
6. Refer to the site specific shop drawings to determine which position on the Voice CPU Card the
module is to be installed in.
7. Insert the VN2001-A1 through the specified knockout opening on top of the VCA2002-A1 Card
Cage and carefully press it into the multi-pin connector mounted on the VCC2001-A1 Voice
CPU card. The multi-pin connector is located approximately 21/2”below the knockout opening,
as illustrated in Figure 5. Install the second module for the other link in the same manner
through the remaining knockout opening.
8. Tighten the fastening pin on the top of each module (see Figure 5) by turning it clockwise until

the modules are firmly held in place by the Card Cage.
NOTE: If it becomes necessary to deinstall the VCC2001-A1 Voice CPU Module, first remove the
Ethernet modules that have been mounted on it.

9. Replace the Card Cage cover by re-inserting it into the top of the Card Cage and sliding it
downward until it reaches bottom.
10. Screw the cover latch back into the Card Cage cover.
Mounting the VN2001-A1 Ethernet Module, 10/100 BaseTx, in an FN2012-A1 Ethernet Switch (Modular)
1. Remove the screws fastening the cover to the body of the FN2012-A1 Ethernet Switch
(modular) and lift the cover off the assembly.
2. Please refer to Figure 6. If necessary, remove one of the knockouts in the FN2012-A1 Ethernet
Switches (modular) side panel.

WIRING
There are no wiring operations for installing the VN2001-A1 onto the VCC2001-A1 Voice CPU card or
into an FN2012-A1 Ethernet Switch (modular).
When using the VN2001-A1 Ethernet Module (10/100 BaseTx) to connect FV2025/2050 Panels, consult
the site-specific shop drawings for instructions on cabling FV2025/2050 Panels together to establish
Ethernet rings. A single multi-conductor cable is used to connect from one module to the next in the ring.
Ethernet cable specifications are provided in Siemens Industry, Inc., Building Technologies Division,
