Set the Zone Option switches on the Controller and
Zone Expansion Unit(s).
NOTE: For each zone used, no
matter what its function, this
switch needs to be set to one
of three settings for proper
zone operation.
The Controller has eight
switches for zones 1-8. Each
subsequent Zone Expansion
Unit has switches for zones
9-24, 25-40, and 41-56.
Refer to the Zone Map and
Zone Configuration Tables
filled out during facility paging
system design. You can find
these in the PagePac System
Installation and Configuration
Guide.

Measure the resistance of each home run wiring with an ohmmeter.
Any pair indicating a value of less than 15 ohms must be rechecked
for possible shorted wiring or speakers. Correct any problems and
retest.
Test speaker wiring for short circuits
NOTE: DO NOT over tighten
zone connector screws.
CAUTION: A 70V audio output
setting going to other than
speakers may damage other
equipment
The zone connectors on the Controller and Zone Expansion Units can
accommodate up to two 22 AWG wires or four 24 AWG wires per zone
output. Check zone option switch setting with Zone Map and Zone
Configuration Tables as you connect each zone.
Powering Up System
With all zones wired and connected to the Controller and Zone
Expansion Unit(s), initial testing can begin. Once initial testing is done,
you can begin to program the Controller with the features for each zone.
NOTE: If during power up, the
system does not respond as
described, refer to the
Troubleshooting section of this
guide, and/or the PagePac
Plus System Installation and
Configuration Guide for
detailed troubleshooting.

Make zone connections to Controller and Zone
Expansion Units. (See Figures 6 thru 8.)
Plug the power cord into the A.C. input connector on
the AmpliCenter. The following should happen.
The green Power LED on the AmpliCenter will turn on

The green Page Access LED on the AmpliCenter also
turns on, but will go out after a few seconds.
On the Controller, verify that the green Phone System

Enabled LED if off.
4.
On the Controller, verify that the yellow Attendant
Access Enabled LED is off.
5.
The green Power LED on the Zone Expansion Unit(s)
will turn on and stay on.
