wire (connect shield to amplifier terminal G). NOTE: The
amplifier should be located at least 3 feet (1 meter) away
from transformers or other electrical devices and must be
kept away from direct heat or extreme cold. Operating
temperature is 0°C–30°C.
4. Do not run wiring for station commons and entrance panel
speaker in the same cable or conduit. Doing so will cause
the system to experience feedback.
OPTIONAL ACCESSORIES
Install optional accessories according to the instructions
provided.
FINISH INSTALLATION
1. Install the amplifier in the entrance panel housing (OH190
series only) so that it will not interfere with panel mounted
equipment. Directory panel removal and replacement
instructions are included with the entrance panel.
2. Install suite stations on boxes. Do not over-tighten screws.
3. Connect power transformer primary to 117 VAC. Ob-
serve local electrical codes.
TEST AND CHECK-OUT
At the entrance panel, push each button and determine if the
correct suite is buzzed each time. At each suite, push
and
buttons to communicate with someone at the

TROUBLESHOOTING
If the system fails to operate properly, check wiring. If wiring
is correct, check the following points.
Entire System Dead
Check 117 VAC at transformer primary, 16 VAC at
transformer secondary, and wiring to amp.
No Talk
Check wiring to terminals 1 and 2 shorted or open, and
wiring to entrance panel speaker open or shorted. Suite
station may be tested by replacement.
No Listen
Check wiring to terminals 1 and 3 shorted or open and
short between terminals 1 and 2.
No Door Operation
Check wiring to door release shorted or open, defective
door release, and door button on suite station. Check wiring
to terminals 2 and 3 or 1 and E.
No Buzzing
Check wiring to amplifier terminal Z, or ZW entrance panel
push buttons; and wiring to suite station's terminal X.
TALK
Excessive Hum or Distortion
Check wiring installed too close to electrical wiring or
electrical devices; amplifier installed too close to
transformers or electrical devices; twisted pair wiring not
used as required; or amplifier volume set too high.
Radio Interference
Check connection from the amplifier terminal G to
electrical ground. NOTE: This connection is not shown
on the wiring diagram, since the situation is not always
improved by adding it. If problems persist, consult factory
or service representative.
