INTRODUCTION Use the Model XLS-MSE2(R)-ADPT Adapter Kit from Siemens Industry, Inc., to
upgrade existing MXL Systems installed in Model MSE-2(R) backboxes to FireFinder-
XLS/Desigo Fire Safety Modular/Cerberus PRO Modular Systems.The XLS-MSE2(R)-
ADPT Adapter Kit consists of an adapter plate, inner door and outer door.The XLS-
MSE2-ADPT (S54430-C7-A1) inner and outer doors are black; the XLS-MSE2R-ADPT
(S54430-C7-A2) inner door is black and outer door is red.The XLS-MSE2-ADPT and
the XLS-MSE2R-ADPT are identical in all other ways and will be referred to in the
remainder of this document as XLS-MSE2-ADPT.
The adapter plate installs over the existing studs in an MSE-2(R) backbox with the
#1/4 x 20 hex flange nuts supplied and provides four studs on which to mount one
CAB-MP mounting plate (P/N 500-633012) and four studs on which to mount one
PTB (P/N 500-033390).
The inner door has an opening in it for the installation of an operator interface and
other modules. There are eight threaded studs around each opening on the inner
door. These threaded studs allow equipment installation on the door. The equipment
is secured by #10-32 nuts. The inner door is permanently hinged right, is attached to
the backbox by screws, and is secured to the backbox by swell-action latches.
The XLS-MSE2(R)-ADPT is for indoor use only in dry environments.
With this conversion, the maximum battery set that can be used in the backbox is 33
AH (model BTX-1). If larger batteries are required, use either a BB-55 or CAB-BATT
battery box.
When converting an MXL to an XLS/Desigo Fire Safety Modular/Cerberus PRO
Modular system, it may be necessary to use the XLS-EXT-CABLE-PKG (S54430-K1-
A1).This kit includes a 58 inch 60-pin Data Bus cable, a 58 inch 6-pin CAN Bus cable
and a 20 inch 12AWG ground wire.
To convert an MSE-2(R) backbox from an MXL System to an XLS/Desigo Fire Safety
Modular/Cerberus PRO Modular component system, you must first disassemble the
MXL and then assemble the XLS/Desigo Fire Safety Modular/Cerberus PRO Modular.
This two-part procedure is described in detail below.
DISASSEMBLY OF MXL SYSTEM
Remove all system power, first battery and then AC.
1. Remove and discard the outer door and the hardware used to secure it in
place.
2. Disconnect and remove the modules from the inner door.
