The relays in the PGD(2)-U10 ADP can optionally control customer-provided
external ringers (loud bells) and buzzers. When an extension user dials the ACI
analog port extension number, the associated PGD(2)-U10 ADP relay closes and
activates the ringer. You could use this ability to control an emergency buzzer for
a noisy machine shop floor, for example. In addition, if programmed for ringing, an
incoming trunk call can activate the ringer/buzzer.
Installing an External Recording System or External Ringer
To connect to the PGD(2)-U10 ADP:
1. Make sure the jumper in the PGD(2)-U10 ADP for the channel is set
correctly. (Refer to
9-4).
2. If a line cord was not previously connected to the PGD(2)-U10 ADP,
complete Steps 3~6. Otherwise, skip to Step 7.
3. Install a modular jack for each PGD(2)-U10 ADP. 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
PGD(2)-U10 ADP.
7. Connect an RCA jack to the audio output(s) on the back of the
PGD(2)-U10 ADP.
8. The opposite end of this cable is connected to the external recording system
or external ringer either directly or by connecting to the cross-connect block
where the item is connected. Refer to
