lation does not require the services of an authorized
agent. However, the installation procedures detailed in
this manual should...

IntroductionIM! 66-031
Disconnect all equipment not owned by the telephone

MOUNTING 
CONSIDERATIONS
l
The KSU should be attached vertically to any stur-
dy, flat, surface. It may be vertically rack mounted
if desired.

l
The KSU must be located within six (6) feet of a
proper electrical outlet. The power supply requires
a dedicated 
117VAC  .15 AMP circuit, with a third-
wire ground, supplied to a standard (NEMA 
515R)
electrical outlet.
 l 
The distance between the KSU and the
TELCO/PBX  jacks must be 25 feet or less as per
FCC...

The polarity between the individual wires in a par-
ticular voice or data pair is not critical; however do
not connect the voice circuits to the data 
CirCuits.

Area 
Paging Interface - Station PA Port
A station port can be configured by class of service
programming to be a PA port. As a PA port, it can be
used to couple a station voice path to an external device
(see Chapter 3 for programming details).
The audio input of an external paging amplifier can
be connected to the audio pair of the station port as
illustrated in Figure 2-3.
The audio input connection must be isolated with a
600 ohm to 600 ohm audio matching transformer.
