SV9100 System Hardware Manual 7-11
Each PGDAD audio output can optionally support two analog Door Boxes. In
addition, you can connect each circuit control relay to an electric door strike. This
allows an extension user to remotely activate the door strike while talking to a
visitor at the Door Box. The control relays are normally open. The GCD-CP10 also
provides one general purpose relay. The GCD-CP10 relay 0 is assigned to the
door box extension port in Program10-05-01. When the relay on the PGDAD is
used, there is no need to assign the relay to the Door Box. Connect the relay as
detailed in the steps below for the Door Box used. The relays on the PGDADs are
numbered 5-8.
1. Make sure the jumper in the PGDAD for the associated Door Box 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.
7. If wall mounting the Door Box, remove the screw on the front of the Door
Box.
8. Remove the back half of the Door Box and attach this mounting bracket to
the wall with the two screws provided.
9. Connect the two-conductor station cable from the CN4 connectors in the
PGDAD to the Door Box terminals. These wires must be routed through the
opening in the bottom of the Door Box mounting bracket..
10. Replace the front half of the Door Box and reattach the screw to secure it in
place.
NOTE

The relay closes when the Door Box/external page zone is called. The
maximum applied voltage is 24vDC at .5A for each contact.
CAUTION
A PGDAD circuit used for an analog Door Box cannot be used for
External Paging.
NOTE

Be sure to maintain the proper polarity.
