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
