Installation and Power Limited Wiring Instructions
Model MLE-6
Enclosure for the MXL/MXLV Control Panel
INTRODUCTION
Model MLE-6 from Siemens Industry, Inc. is a
large-size enclosure for the MXL/MXLV System.
The enclosure consists of a backbox and front
door that is shipped assembled. Note that the
backbox has a flanged lip to permit semi-flush
mounting in addition to the usual surface
mounting.
Consider the following when mounting the
backbox:
• Mounting height for visual and manual
access to the MKB-2 Keyboard/annunciator
• Weight and size of enclosure
• Local mounting codes
Fasten the backbox securely to a clean, dry,
shock-free, and vibration-free surface. MLE-6
enclosure is for indoor use only in dry environ-
ments. Position the backbox clear of obstruc-
tions so that the front door opens freely and so
that the indicators and controls are easily
accessible.
NOTE: When the backbox is mounted semi-
flush, be sure that the position of the
backbox permits the front door to
swing fully open.
To install the MLE-6 backbox:
(Refer to Figure 1.)
1. Slip the front door off the hinges of the box
and put it to one side temporarily.
2. Remove the knockouts in the backbox
where field wiring is required.
3. Hold the empty backbox against the wall at a
height that provides easy access.
4.
Mark drill points on the wall in the center of the
two slots on the upper rear of the
backbox
.
5. Drill the two holes and screw in the top bolts,
leaving a gap between the wall and the rear
of each bolt head.
6. Mount the backbox on the two bolts and then
install the bottom bolts in the two holes provided.
7. Tighten all bolts securely against the back
wall of the backbox.
8. Slip the front door back on the hinges of the
backbox (See Figure 2).

WIRING
In compliance with UL-864, effective May 1, 1995,
all power limited fire protective signaling conduc-
tors must be separated a minimum of 1/4 inch from
all of the following items located within a control
panel:
• electric light
• power
• Class 1 or non-power limited fire protective
signaling conductors
To meet the above requirements, the following
guidelines must be observed when installing
modules and wiring to this control panel.
NOTE: If power-limited wiring is not used within
an MXL/MXLV enclosure, then the follow-
ing guidelines do not apply. In that case,
be sure to follow standard wiring practices.
FRONT DOOR
The front door is the main outer door for the
MLE-6 enclosure. The door is supplied
without filler plates for the three large
openings. To select the appropriate filler
plates for the three openings, follow the
information below.
•When visual indication of system
operation (LCD, LED, or printer) is
required, install clear panels, the MDL-1
lens, behind the appropriate door
openings.
•When visual indication of the system
operation is not required, install plain
blank panels, MDB-1s, behind the
appropriate door openings.
•When audio amplifiers such as the
EL-410C/D or ZAC-30 are used,
install the MDG-1 (MXL Door Venting
Grill) behind the appropriate door
openings.
•After determining which filler plates
are required, insert the appropriate
plates in the front door as shown in
Figure 3 using the hardware supplied.

WIRING ENTERING ENCLOSURE
Non-Power Limited Wiring
Wiring to the following MXL/MXLV module
terminations (See Table 1) is considered non-
power limited and must enter the enclosure
through the knockouts dedicated to non-power
limited wiring. Wiring between these knockouts
and the module terminations must be in the short-
est route and must not overlap any other wiring.
If the system contains more than four zone
cards, place a second PLC-4 in the upper right
module position of the second OMM-1. Locate
this OMM-1 in the right side of the enclosure. If
more than two PLC-4s are required, install
additional PLC-4s in the same relative position in
additional OMM-1s located in the lower row of
the enclosure.
WIRING IN ENCLOSURE
Non-Power Limited Wiring
The following wiring is considered non-power
limited:
• from the MPS-6/-W or MPS-12/-W
• from the batteries to the MMB
• from the MMB (P3) to the MOM-4 (P5)
• from the TSP-40 to the MOM-4 (P8) – optional
To maintain the required 1/4 inch separation
from other wiring, these wires must be routed
and held in place by a separate wire support.
This support is positioned on the left side wall of
the enclosure.
To provide the separation, follow the steps listed
below:
1. First locate the wire standoffs in the bracket
located on the left side of the enclosure.
2. Next place these wires in the standoffs, close
the clamp located on the standoff, and then
route the wires to the appropriate
terminations as shown on the connection
diagram/manual.
3. When the optional TSP-40 is used, route the
interconnecting cable directly to the MOM-4
(P8) and not over any other wiring.
WIRING ENTERING ENCLOSURE
Power Limited Wiring
Note: Power limited circuits must use type
FPLP, FPLR, or FPL cable per article
760 of the NEC.
Wiring to the following MXL/MXLV module
terminations (See Table 2) is considered power
limited and must enter the enclosure through
knockouts dedicated to power limited wiring.
Wiring between these knockouts and the module
terminations must be in the shortest route and
most not overlap any other wiring.
† When the CSM-4 is used as Municipal Tie or
Releasing Service.
‡ Audio or strobe power wiring to any ZC Zone Card
module and ASC-1/-2 first must be terminated at a
PLC-4 plug-in module installed in an OMM-1 and
then at the zone card. The PLC-4 must contain at
least one of the following plug-on boards: a
PL864-25A or PL864-70A for audio circuits, or a
PL-864-25S for strobe circuits. Refer to the PLC-4
Installation Instructions, P/N 315-093312.
If there are no MOM-4/CRM-4s installed in the
system, install the PLC-4 in the lower left mod-
ule position of the OMM-1 in the left side of the
enclosure. Wire between the PLC-4 and the
appropriate zone card in accordance with the
instructions accompanying these modules.
If the system contains more than four zone
cards, place a second PLC-4 in the upper right
module position of the second OMM-1. Locate
this OMM-1 in the right side of the enclosure.
If
more than two PLC-4s are required, install addi-
tional PLC-4s in the same relative position in
additional OMM-1s located in the lower row of the
enclosure.
If there are MOM-4/CRM-4s installed in the
system, install the OMM-1 in the lower left
module position of the OMM-1. Wire between the
PLC-4 and the appropriate zone card in accor-
dance with the instructions accompanying these
modules.

considered non-power limited and must enter and
exit the enclosure through knockouts dedicated to
non-power limited wiring. Wiring between these
knockouts and the module termination must be in
the shortest route and must not overlap any other
wiring. Refer also to the DV-100 Wiring Diagrams,
P/Ns 315-192756 and 315-192757, as applicable.
