The Electra Elite IPK II allows a maximum of 56 PGD(2)-U10 ADPs to be
installed [48 for ACI (external MOH or external recording system) ports, four
for Door Boxes, and four for Paging]. The PGD(2)-U10 ADP also provides
multipurpose control relays. These control relays can be used to control the
external amplifier, external music source and door lock control using a Door Box.
The system allows up to eight general purpose relays with the PGD(2)-U10
ADP.
The PGD(2)-U10 ADP connects to any available digital extension port. The
terminal connections made in the PGD(2)-U10 ADP and the jumper settings
determine what features are used for each circuit.
The PDG(2)-U10 ADP can be connected only to an ESIB(8)-U20 ETU. If the
PDG(2)-U10 ADP is connected to an ESIE(8)-U20 ETU, it is not recognized.
When an ESIB(8)-U20 ETU has an ESIE(8)-U20 ETU installed [ESIB/E(16)],
the PGD(2)-U10 ADP has both channels available for Paging, MOH, External
Ringers or Door Box according to the strapping on ports 1~8. The
corresponding port on the ESIE(8)-U20 ETU does not support a station or
other hardware (It is used by the PGD(2)-U10 ADP for channel 2). When an
ESIB(8)-U20 is installed without the ESIE(8)-U20 ETU installed, a
PGD(2)-U10 ADP installed on ports 1~8 is recognized, but only channel 1 on
the PGD(2)-U10 ADP is supported. Channel 2 is unavailable. ESIB(8)-U10
ETUs and ESIE(8)-U10 ETUs do not support the PGD(2)-U10 ADP.
