Fiber Optic Interface
Fire Safety
INTRODUCTION
The Model D2300CPS from Siemens Building Technologies, Inc. (See Figure 1) is a Fiber Optic interface
for the MXL’s RS-485 network (MNET or XNET) or
the FireFinder XLS network (HNET or XNET). It uses
a two-fiber (duplex) pair between each device. The
D2300CPS can function as either a repeater or an
end point unit.

WARNING: This module is NOT backwards
compatible with the existing 2300CP. This unit
uses +24VDC. Make sure to read the front of the
module and connect to the correct voltage.
Otherwise, serious damage to the unit will result.

The D2300CPS 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.

MOUNTING
The D2300CPS 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 D2300CPS 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
D2300CPS 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
D2300CPS
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 D2300CPS 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 D2300CPS modules in any FireFinder XLS 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 D2300CPS modules onto the
D2300-MP. Mount the D2300CPS modules prior to
installing the D2300-MP onto the CAB-MP. Note that
when using two D2300CPS modules, the center two
mounting holes on each D2300CPS share the two
center studs on the D2300-MP (See Figure 5).
over them. Tighten the four screws.
WARNING:
The D2300CPS module is not listed for use by
Factory Mutual. Applications requiring fiber connectivity of voice modules/systems are therefore
not Factory Mutual listed.
WARNING:
Do not use the D2300CPS with CXL Systems.
