5.1 External Page
Two external page zone/door box circuits are provided by each PGDAD installed.
Each Door Box/external page circuit provides a dry relay contact. The GCD-CP10
also provides a connection for external paging and a relay. The external page on
the GCD-CP10 is speaker number 9 – the relay is number 0. The external page
speakers provided by the PGDADs are 1~8 – the relays on the PGDADs are
numbered 1~8.
The PGDAD can be used for talkback with External Page, as can a CO trunk port
with the proper external page equipment (ex: Valcom) – set Program 31-06-03 to
0 for talkback. However, the external page circuit on the GCD-CP10 cannot be
used for talkback.
5.2 Installing an External Page System
1. Connecting to the GCD-CP10:
Connect an RCA line from the AUX1 or AUX2 connector on the GCD-CP10
to the appropriate location on the extension cross-connect block.
2. Connect the two-conductor station cable from the cross-connect block to the
external relay/external page.
3. Install bridging clips as required.

1. Connecting to the PGDAD:
Make sure the jumper in the PGDAD for the channel is set correctly. (Refer
to
Figure 7-4 PGDAD Jumper Settings on page 7-4 ).
2. If a line cord was not previously connected to the PGDAD, complete Steps
3-6. Otherwise, skip to Step 7.
3. Install a modular jack for each PGDAD. For each module, run one-pair 24
AWG station cable from the cross-connect block to a modular jack. Ground
the unused pair.
4. Terminate the extension leads to GRN/RED of the modular jack. Terminate
the unused leads to the jack.
5. Install bridging clips as required.
6. Plug a modular line cord from the mod jack to the CN1 connector on the
PGDAD.
CAUTION
A PGDAD circuit used for External Paging cannot be used for an analog
Door Box.
