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.

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.
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.

• from the batteries to the MMB
1, 2, 3
• 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
2. Next place these wires in the standoffs, close
3. When the optional TSP-40 is used, route the
