Model ZCT-8B
Zone Control Telephone Card Module

OPERATION

The Model ZCT-8B Zone Control Telephone
Card from Siemens Industry, Inc. has eight
telephone zones. The name indicates the follow­ing 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, pro­tected, 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 print­out 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.

INSTALLATION

first battery and then AC. (To power up,

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.

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
in the OMM-1 edge connector for the ZCT-8B

key

as

shown in Figure 2. See Figure 3 for the exact

OMM PIN NUMBERS

Figure 2

Placing the Card Slot Key in the OMM-1

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 cor­rectly. 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.
