DISASSEMBLY OF MXL -IQ SYSTEM
Use the Model XLS-MSE3(R)-ADPT Adapter Kit from Siemens Industry, Inc., to
upgrade existing MXL -IQ Systems installed in Model MSE-3L(R) or MSE-3M(R)
backboxes to FireFinder-XLS/Desigo Fire Safety Modular/Cerberus PRO Modular
Systems. The MSE-3L(R) and MSE-3M(R) will be referred to as MSE-3(R) in the
remainder of the document.
The XLS-MSE3(R)-ADPT Adapter Kit consists of an adapter plate, inner door and outer
door. The XLS-MSE3-ADPT (S54430-C14-A1) inner and outer doors are black; the
XLS-MSE3R-ADPT (S54430-C14-A2) inner door is black and outer door is red. The
XLS-MSE3-ADPT and the XLS-MSE3R-ADPT are identical in all other ways and will be
referred to in the remainder of this document as XLS-MSE3-ADPT.
The adapter plate installs over the existing studs in an MSE-3(R) backbox. The inner
door has an opening in it for the installation of a FCM2041-U2/-U3 operator interface
and either one ID-MP mounting plate or one ID-SP blank plate. The inner door is
permanently hinged right and is attached to the backbox by screws.
The XLS-MSE3(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 18
AH (model BP-61). If larger batteries are required, use either a BB-55 or CAB-BATT
To convert an MSE-3(R) backbox from an MXL -IQ System to an XLS/Desigo Fire
Safety Modular/Cerberus PRO Modular component system, you must first disas-
semble the MXL -IQ and then assemble the XLS/Desigo Fire Safety Modular/Cerberus
PRO Modular. This two-part procedure is described in detail below.
Remove all system power, first battery and then AC.
Remove and discard the outer door. Reserve the hardware used to secure it
Disconnect and remove the modules from the inner door.
Remove all modules from the backbox, making sure to mark all wires.
Reserve the hardware used to secure them in place.
Remove the MPS power supply and batteries from the backbox.
