Installation
Connecting The External Paging Interface At A Station PA Port
You can program any station port as a PA port and
use it to couple a station voice path to an external
paging amplifier. Refer to Chapter 4 for programming
details.
l
Connect the audio input of an external paging
amplifier to the audio pair of the station port at the
J-1 or J-2 connector blocks.
l
Isolate the audio input connection with a 600 ohm to
600 ohm audio matching transformer. Terminate
the audio input of the paging amplifier with a 600
ohm (nominal value)
resistor.
l
If you program station port 15 as a PA port, the
system automatically reconfigures the Common
b
Audible contact points on J-2 as PA enable
terminals. The contact closure now occurs when
PA station 15 is dialed. The system disables the
normal common audible function as long as station
15 is a PA station.
If you program station port 17 as a PA port,
the
system automatically reconfigures the Auxiliary
Station Interface (station
17
audible) as PA enable
terminals. The contact closure now occurs when
PA station 17 is dialed. The system disables the
normal auxiliary station interface function as long as
stat-on
17 is a PA station.
