Model D2325CPS
Single Mode (1310nm) Fiber Optic Interface
INTRODUCTION
The Model D2325CPS from Siemens Industry, Inc. (See
Figure 1) is a Fiber Optic interface for the MXL’s RS-485
network (MNET or XNET), FireFinder XLS/Desigo Fire
Safety Modular/Cerberus PRO Modular network
(HNET or XNET) and HUB-4 FSI. It uses a two-fiber
(duplex) pair between each device. The D2325CPS can
function as either a repeater or an end point unit.

D2325CPS Module
The D2325CPS can operate in either a daisy chain
(See Figure 2) or star configuration (See Figure 3).
This allows for network configurations that are not
possible with the RS-485 network alone.
WARNING:
The D2325CPS module is not listed for use by
Factory Mutual. Applications requiring fiber con-
nectivity of voice modules/systems are therefore
not Factory Mutual listed.
WARNING:
Do not use the D2325CPS with CXL Systems.
MOUNTING
The D2325CPS has four keyhole slots for #6 screws.
Mount the device in the locations listed below using
the four #6 screws provided.
A bracket (P/N 500-692880) is available for mounting
the D2325CPS in any MXL enclosure that will accept
a MOM-4 (See Figure 4). This bracket has the same
footprint as the MOM-4 and accommodates two
D2325CPS modules. An assembly kit is included with
the bracket that contains four nuts and eight screws.
Mount the bracket in the enclosure with the four nuts
at the positions labeled
X
(See Figure 4). Start four of
the 6-32 screws and slip the keyhole slots in the
D2325CPS over them. Tighten the four screws.
System 3 style rails that mount on an MBR-2 or MME-3
backbox (P/N MSR-1) are also available and can be
used for mounting the D2325CPS with the System 3
MPFO Bracket. Up to three brackets can be installed on
a single rail.
A bracket, Model D2300-MP, is available for mounting
two D2325CPS modules in any FireFinder XLS/
Desigo Fire Safety Modular/Cerberus PRO Modular
CAB enclosure. The D2300-MP fits in the same
footprint as a CC-5 and mounts to the CAB-MP. A
hardware kit is provided for attaching the D2300-MP to
the CAB-MP and mounting two D2325CPS modules
onto the D2300-MP. Mount the D2325CPS modules
prior to installing the D2300-MP onto the CAB-MP.
Note that when using two D2325CPS modules, the
center two mounting holes on each D2325CPS share
the two center studs on the D2300-MP (See Figure 5).
ELECTRICAL CONNECTIONS
POWER INPUT
The D2325CPS uses filtered or unfiltered 24 VDC.
The D2325CPS can only be powered from the
sources listed in Table 1 on page 6.
