Card Rack Installation
1. Open the Centra-Page system central cabinet to access the front panel.
2. Slide the Model 69460-001 Card into the card rack slot associated with the speaker to be muted.
Ensure that the connector at the rear of the card has plugged firmly into the connector in the card
rack.
3. Snap the white clip on the front of the card into place to secure the card in the card rack.
4. Open the Centra-Page cabinet to access the rear of the card rack. Attach the new terminal block label
as noted in Figure 2.
5. Use No. 14, 16, or 18 AWG cable to complete the connections to the speakers. The distance between
the central cabinet and the speakers determines the wire gauge that is required: the greater the
distance to be covered, the larger the wire gauge that is needed. Refer to GAI-Tronics Pub. 42004-
135 for more information on speaker installation and wiring.
6. Refer to Figure 2 and Figure 3. The Model 10961-001 AMI Centra-Page Interface is equipped with a
Crew’s Quarters activation output (TBX04 position 9 - the black wire). Connect the black wire from
the 10961-001 TBX04 to the card rack terminal block position 2. Jumpers P1, P2 and P3 on the
69452-001 Interface PCBA are used to control which of the three tones will be broadcast to the
crew’s quarters. The jumper in position 1 and 2 make the tone non-active. The jumper in position 2
and 3 make the tone active. One or all the jumpers can be active. For example, to broadcast tones 1
and 2 only to the crew’s quarters, put P1 and P2 in position 2 and 3 and allow P3 to remain in
position 1 and 2.
