Model ZCT-8B
Zone ControlTelephone Card Module
OPERATION
The Model ZCT-8B Zone Control Telephone
Card from Siemens Industry, Inc. has eight
telephone zones. The name indicates the follow-
ing information:
ZCT – Zone Control Telephone card
8B – 8 Zone Style Y telephone zone output circuits
The ZCT-8B connects to the telephone riser
through the OMM-1 Output Master module.
All ZCT-8B zone circuits are supervised, pro-
tected, and for Class B (Style Y) zone use only.
The module provides both dial and busy tones.
Up to five telephones can be on line at the same
time.
The ZCT-8B occupies one of eleven
subaddresses of the OCC-1 Output Control Card
module. When installing a zone control module,
use the CSG-M (AccuLINK) configuration print-
out to locate the address of each zone control
card. Use switch S1 to set a unique address for
up to zone control cards as described below.
For additional information on the Voice System,
refer to the MXLV Manual, P/N 315-092036.
INSTALLATION
Remove all system power before installation
first battery and then AC. (To power up, con-
nect 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 function section of the CSG-M
configuration printout for the address of the
module.
3. Set the card address on switch S1 using
switches SW1 – SW4.
a. Refer to Figure 1 for the location of S1.
b. Refer to Table 1 for switch settings (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.
Do NOT install the card in its edge connector
until ALL OMM-1 field wiring is completed and
checked for shorts, opens, and other faults.
Refer to the Wiring Checkout Chart. Replace
the card in its protective bag if the wiring is not
complete.
Find the card slot key provided in the installation
kit with the ZCT-8B board. Place the card slot
key
in the OMM-1 edge connector for the ZCT-8B as
shown in 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 ZCT-8B
slot. Two other keys already installed in the
OMM-1 prevent reverse installation of the card in
the OMM-1 edge connectors. (See Figure 3.)
Place the card in its card edge connector cor-
rectly. 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.
