Issue 1
2. Connect 8-pin Molex from Controller to first
Z.E.U., and next Z.E.U’s, if used.
NOTE: Up to 3 Z.E.U.s can be used, providing up
to 56 paging and/or control zones.
3. Set DIP switches on each Z.E.U .(s).
4. Set the Zone Option switches on the
Controller and Z.E.U.(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 before
applying power to the system.
The Controller has eight switches for zones 1-8.
Each subsequent Z.E.U. has switches for zones
9-24, 25-40, 41-56.
INSTALLATION
MOUNTING
NOTE: When installing the Zone Expansion Unit,
leave at least four inches of space above and
below for proper ventilation.
Installing the paging equipment in a ventilated
room where there is easy access to speaker
cabling (preferably in the tel ephone equipment
room). Disconnect all power before installing
equipment.
1. Mount the Zone Expansion Unit(s)(Z.E.U.) to
either a wall, cabinet or a rack (below the controller).
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.
5. Locate and mount all speakers in accordance
with the floor plan drawing for this installation.
6. Connect each speaker to the appropriate
Home Run or Speaker-to-Speaker wiring
scheme as shown on the floor plan.
NOTE: Adjust all speakers p er volume and power
requirements as noted on floor plan, during or
after installation. Figures 7 and 8 show wiring
methods using local and zone connector blocks,
and contact closure zone applicat ions.

7. Test speaker wiring for short circuits.
Measure the resistance of each Home Run wi ring
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.
8. Make zone connections to Controller and
Z.E.U. (see Figures 5 thru 7).
The zone connectors on the Contr oller and Z.E. U.
can accommodate up to two 22 AWG wir es 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.
NOTE: DO NOT over tighten zone connector
screws.
Powering Up System
With all zones wired and connected to the Controller and Z.E.U.(s), initial testing can begin.
Once initial testing is done, you can begin to program the Controller with the features for each
zone.
1. Plug the power cord into the AC input connector on the AmpliCenter®. the following should
happen:
a. The green Power LED on the AmpliCenter
will turn on and stay on.
b. The green Page Access LED on the
AmpliCenter also turns on, but will go out
after a few seconds.
c. On the Controller, verify that th e green
Phone System Enabled LED is off.
d. On the Controller, verify that the yellow
Attendant Access Enabled LED is off.
e. The green Power LED on the Z.E.U.( s) will
turn on and stay on.
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 troublesh ooting.
TROUBLESHOOTING
Some common problems encountered when the
paging system is not operating are described
below. Check each item in the order listed.
1. No AC power to AmpliCenter or Controller
(they supply power to the Z.E.U.(s)).
2. Host telephone system failure.
3. Host system page port failure.
4. A hardwire disconnect between host system
and Controller.
5. AmpliCenter, Controller, or Z.E.U. zone
switches or DIP switch settings tampered with .
If the problem has not been resolved by checking
the preceding items, refer to the troubleshooting
tables in the PagePac Plus Install ation and Configuration Guide.
Controls and Indicators, Terminals and
Connectors
Figure 9 shows the controls and indicators, terminals and connectors on the rear panel of the
Z.E.U.(s). Table 1 identifies them by function.
