The Model OCC-1 Output Control Card
from Siemens Building Technologies, Inc.
is an MXLV module that controls Voice
system cards (such as the zone cards)
that plug into the OMM-1 Output Master
module. Commands received from the
MXL system through the network bus are
processed by the OCC-1. The commands
are then sent to the other cards in the
system for implementation.
At least one OCC-1 is required in each
MXLV System. It supervises and controls
up to 11 plug-in cards, each having a
unique subaddress. Several types of
system cards connect to the OCC-1.
1. Up to three audio risers connect to the
OCC-1. These signals are available to
the power amplifiers.
2. The BTC-1 Backup Tone card is an
optional module that also plugs into
the OCC-1. In an installation with
distributed amplification, the BTC
provides the tone for the degrade
mode of operation; then, if Network
Communications fail and a local alarm
is detected, the tone from BTC-1 is
available at the Channel A amplifier
input.
3. The telephone riser also connects to
the OCC-1. The telephone signal is
routed through the OMM-1 telephone
riser bus to any ZCT-8B telephone
zone control cards that are plugged
into the OMM-1.
The OCC-1 supervises the cards under its
control, such as the ZC zone card series.
As each card is supervised by the OCC-1,
the card responds with its status. The
status information is then sent to the MXL.
The OCC-1 occupies a network address.
Set the address on switch S1. When
installing an OCC-1 card, use the CSG-M
(AccuLINK) configuration printout to locate
the address of the card. Follow the switch
setting instructions in Table 1 to set the
desired address.
For additional information on the Voice
System, refer to the MXL/MXLV Manual,
P/N 315-092036.
INSTALLATION
Remove all system power before
installation, first the battery and
then AC. (To power up, connect the
AC first and then the battery.)
1. Remove the card from its protective
bag. Do not touch the gold edge of the
board.
2. Refer to the CSG-M configuration
printout for the address of the module.

3. Set the card address on switch S1
using dipswitches SW1-SW8.
a. Refer to Figure 1 for the location of
switch S1.
b. Refer to Table 1 for the switch
settings.
c. Set the address (See NOTE below).
NOTE: To open a dipswitch, press
down on the side of the dipswitch
marked OPEN. To close a dipswitch, press down on the side of
the dipswitch opposite the side
marked OPEN.
To open a slide switch, push
the slide to the side opposite the
side marked ON. To close a slide
switch, push the slide to the side
marked ON.
4. There is a jumper E1 on the OCC-1.
Refer to Figure 1 for its location. If theEL-410C/D amplifier is used, place
jumper E1 in the right-hand position.
This connects the backup amplifier
input negative side to the MXLV power
supply.
5. Switch S2 is not presently used, but it
must be left in place.
6. Do NOT install the card in its edge
connector until ALL OMM-1/-2 field
wiring is completed and checked for
shorts, opens, and other faults. Refer
to Wiring and to the OCC-1 WiringCheckout Chart. Replace the card in
its protective bag if the wiring is not
complete.
7. Place the user key from the installation kit in the OMM-1/-2 card edge
connector for the OCC-1 (See Figure
2). See Figure 3 for the exact location
of the key for this module. This prevents installation of any other card
type in the OCC-1 slot.
CAUTION
At all times handle any plug-in
cards with extreme care. When inserting or removing a card, be
sure the card is kept at right
angles to the OMM board. Otherwise, the plug-in card can damage
or displace other components.

8. Two keys to prevent reverse installation of the card are already factory
installed in the OMM-1/-2 edge connectors (See Figure 3).

9. After completing and checking all field
wiring, place the card in its card edge
connector. The components on the
board must face the 22-position
terminal block where the wiring is
terminated. Press the card firmly in
place to be sure it is seated properly in
the edge connector.

Notes:
1. If this OCC-1 is the last or the only OCC-1, terminate the
inputs shown as follows:
4. Configure Generic input with CSG-M for either NC or NO dry
contact input or normally low or normally high 5/24 VDC input.
Generic input supervision is enabled in CSG-M for any type of
power failure.
a. Wire the NC or NO dry contact input across terminals
13 and 14.
b. Wire the normally low or normally high 5/24 VDC input
to terminal 14. (Normally low = high going input;
Normally high = low going input. The EL-410C/D power/
battery supervision is normally low input.)
5. Refer to Wiring Specification for MXL, MXL-IQ and MXLV
Systems, P/N 315-092772 revision 6 or higher, for additional
wiring information.
6. Positive and negative ground fault detected at <70K ohms
for terminals 17-22.
