1Ethernet switch (modular) FN2012-A1
1.1 Description
The Ethernet switch (modular) FN2012 is intended exclusively for the operation of an
Ethernet network for the physical connection to voice and VoIP components for use in
fire detection.
The Ethernet switch supports the transmission of degraded mode signals system-wide
via Ethernet and an extension to the ground fault supervision for the electric Ethernet.
It also supports the physical connection to voice and VoIP components.
The Ethernet switch has two slots for optional Ethernet modules. Depending on the
application, the Ethernet switch is supplied via a 24 V input, via PoE using the Ethernet
module (electric), or via the connection module (MoNet) FCA2031.
Intended use
●Integrated switch for Ethernet backbone in FS20/FS920 and XLS fire detection
systems
●VoIP switch for Integrated Voice
●Integrated voice switch
●Operation as an Ethernet repeater
●Remote switch for external products, for example if a management station is
connected

Properties
●Can be installed in approved FS20/FS920 housing
●Can be installed in approved XLS housing
●2x Ethernet ports for local Ethernet (panel-internal)
●2x Ethernet ports for external Ethernet (increased EMC safety and ground fault
supervision)
●MoNet bus connection for transmitting signals from the peripheral data bus and
SAFEDLINK degraded mode signals via the connection module (MoNet)
●Configurable via a 16-pin rotary switch
●1x dry contact relay output for fault signals
●Transmission of degraded mode signals from the system and the FCnet/C-WEB
network should the main CPU fail
●Several supply options
–Via the supply connection (redundant)
– Via PoE with optional Ethernet module (electric)
–Via MoNet bus
●2x slots for optional Ethernet modules (ring ports) – not included in scope of supply
–VN2001 Ethernet module (electric) for distances up to 330 ft/100 m
–VN2002 Ethernet module (MM), optical Ethernet module for distances up to
13123 ft/4 km with an 11 dBm loss 1
–VN2003 Ethernet module (SM), optical Ethernet module for distances up to
131233 ft/40 km with a 29 dBm loss 1
1The length is a guide value dependent upon the loss of the optical cable

2Installation
2.1 Installation in FS20/FS920 housing
The Ethernet switch (modular) FN2012 can be installed in all FS20/FS920 housings
(1HU and 2HU). The example below illustrates installation in a fire control panel in the
housing (2HU).
If the Ethernet switch (modular) is used as a repeater, it is installed as a separate
component in an external housing (1HU).
Figure 1: Installing the Ethernet switch (modular) in housings (2HU)
