Figures 7 and 8 show wiring methods using
local and zone connector blocks, and contact
closure zone applications.
7. Test speaker wiring for short circuits.
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.
8. Make zone connections to Controller and
ZEU (see Figures 5 thru 7).
The zone connectors on the Controller and
ZEU 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.
NOTE: DO NOT over tighten zone
connector screws.
Powering Up System
With all zones wired and connected to the
Controller and ZEU(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 the 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 ZEU(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
troubleshooting.
2. Begin programming the Controller.
A quick reference card for telephone
programming, along with detailed programming
instructions, can be found in the PagePac Plus
System Installation and Configuration Guide,
Programming.
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 ZEU(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 ZEU 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 Installation 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
ZEU(s). Table 1 identifies them by function.
Table 1. Controls and Indicators, Terminals
and Connectors
1 Zone option 3-position slide switch: 70V audio
out, contact closure input and contact closure
output.
2 Zone connector for expansion zones: plus,
minus and ground screw terminals.
3 8-pin Molex connector from controller: power,
control and audio or previous ZEU.
4 8-pin Molex connector to additional ZEU:
power, control and audio.
5 DIP switch to be set when one, two or three
ZEU(s) are used.
