Model OMM-2

Output Master Module

P/N 315-092699-5

INTRODUCTION

The SIEMENS Model OMM-2 Output Master module is the motherboard for all of

the MXLV plug-in boards: the OCC-1, ASC-1/-2, DMC-1, PLC-4, RCM-1, ZAC-30,

and the ZC zone cards. The module has the same dimensions as the MOM-2

MXL motherboard. The OMM-2 mounts vertically in the MME-3L and MLE-6

backbox or horizontally in the MLE-3 backbox and

contains two half-width card

slots

. (Refer to Figure 1.)

Voice system field wiring terminates on the OMM terminal blocks. (See Figure 5.)

Power and network communications are provided by the MMB or the PSR-1,

depending on the application. The network control signals are distributed to the

plug-in cards through the OMM-2. All connecting cables are supplied with the unit.

The MME-3 enclosure has three locations for the OMM-2 (or for OMM-1s, MOM-4s

or MOM-2s). However, when a TSP-40 printer is installed in a system, it decreases

the number of OMMs (or MOMs) to two modules for that enclosure. The MLE-6

enclosure has six locations for optional card cages, such as OMM-1s, OMM-2s,

MOM-4s, or MOM-2s. The MLE-3L enclosure has one location for the OMM-2.

INSTALLATION

(Refer to Figures 2, 3, and 4)

Remove all system power before installation, first the battery and then AC.

(To power up, connect the AC first, then the battery.)

Unpack the OMM-2 and its attached backplate. Inspect it, looking for such things

as connectors not properly installed, missing polarizing keys, dirt, and packing

material on the board.

Check to see if the card guides for the plug-in boards are already installed. If they

are not, install all four of the card guides according to the following directions

before mounting the OMM-2 into the enclosure. Figure 1

To install the card guides:

(Refer to Figure 2)

1. Place the card shoulder on the raised boss at the

end of the card edge connector.

2. Align the hole in the shoulder with the hole in the

boss.

3. Place the mounting screw in the hole in the

shoulder and tighten the screw.

4. Repeat Steps 1 and 2 for the remaining card

guides.

To mount the OMM-2 card cage:

The OMM-2 mounts vertically on the MBR-MP

mounting plate in the MME-3 and MLE-6 enclosure

under the MMB or the PSR as shown in Figure 3.

The OMM-2 mounts vertically in the MSE-3L

enclosure as shown in Figure 4.

The installation kit for the OMM-2 includes the

following:

Three No. 10 nuts

Three washers

One 8-conductor ribbon cable

(P/N 555-190967)

One 14-conductor ribbon cable

(P/N 555-192155)

To mount the OMM-2 in an MME-3 or MLE-6 backbox:

1. Hold the OMM-2 so that the terminal blocks TB4

and 5 are on the left. (See Figure 1.)

2. Place the module on the mounting studs of the

MBR-MP mounting plate in the left-hand

position.

3. Fasten the OMM-2 in position with the hardware

provided as shown in Figure 3.

4. To mount any other OMM-2 modules used in the

system, repeat the above steps. Use the center

position first and then the right-hand position for

the additional modules, as needed.

5. When mounting OMM-2 modules in an MLE-6

enclosure, it may be necessary to reverse the

mounting in the lower row by placing the two

position terminal block TB1 at the bottom instead

of the top (Refer to Figure 6). This will insure that

the 14-conductor cables that are supplied can be

assembled.

To mount the OMM-2 in an MSE-3L backbox:

1. Hold the OMM-2 so that the terminal blocks TB4

and 5 are on the left. (See Figure 1.)

2. Place the module on the mounting studs in the

upper left-hand corner of the enclosure as shown

in Figure 4.

3. Fasten the OMM-2 in position with the three No.

10 nuts provided, placing two on the top of the

module and one on the right bottom. See the

positions marked A shown in Figure 4.

To assign the plug-in cards to the OMM-2:

The cards that can be assigned to plug into the

OMM-2 are the OCC-1, the ASC-1/-2, the DMC-1,

the PLC-4, the RCM-1, the ZAC-30, and the ZC zone

cards. Determine which optional plug-in cards are

used in your CSG-M configuration. Assign the plug-in

cards to the card edge connectors on the OMM-2(s)

as needed.

CAUTION

Handle all plug-in cards with extreme care. When

inserting or removing a card, keep the position of

the card at right angles to the OMM-2 board.

Otherwise, the plug-in card can damage or dis-

place other components. Never insert or remove a

plug-in card with power applied to the panel.

WIRING

(Refer to Figures 5 and 6)

All wiring must comply with

national and local codes.

1. A 2-conductor wire cable (P/N 600-192239) is

supplied with the ACM-1 module to use on the

OMM-2 TB1. Use this cable to connect 24 VDC

from P3 on the MMB to TB1 on the OMM-2

module. When using a PSR-1, connect two

individual 14 AWG wires between the OMM-2 TB1

and PSR-1 TB3-1 and TB3-2.

 The terminals on OMM-2 TB1 are marked

+24V and RET.

 On MMB P3, 1 is positive and 2 is negative.

 On PSR-1 TB3, 1 is positive and 2 is negative.

2. Assign plug-in cards to the card edge connectors

as determined above. Once the terminal block

related to each edge connector is wired, place

only the assigned plug-in card in that edge

connector.

3. Refer to the Installation Instructions listed in Table

1 for directions on wiring to the 22 position

OMM-2 terminal blocks and for attaching these

modules to the OMM-2 terminal blocks.

If the system includes more than one OMM-2,

use

the 14-conductor ribbon cable (P/N 555-192155)

to connect P1 of the first OMM-2 to P2 of the

second OMM-2. If there is a third OMM-2,

connect P1 of the second OMM-2 to P2 of the third

OMM-2. No more than three OMM-2s can be

connected together when they are in an MME-3

enclosusre.

It may be necessary to reverse the module

mounting in the lower row of the MLE-6 enclosure

to insure that the 14-conductor cables that are

supplied can be assembled (See Figure 6).

5. Note that there are two 8-conductor cables. The

long 8-conductor cable (P/N 555-192243), comes

with the ACM-1. Use this cable for communications

and power from P4 of OMM-2 to either P6 of the

PSR or to P6 of the MMB, whichever is present.

This cable is polarized. Observe polarity and DO

NOT USE EXCESSIVE FORCE. The black tracer

on the cable indicates the position of pin 1.

6. If there is more than one OMM-2, use the short

8-conductor cable (P/N 555-190967) to connect P3

of the left-hand OMM-2 to P4 of the OMM-2 that is

to its right.

This cable is polarized. Observe polarity and DO

NOT USE EXCESSIVE FORCE. The black tracer

on the cable indicates the location of pin 1. If there

is a third OMM, repeat this step.

System, refer to the MXLV Manual, P/N
