entrance panel, in a position that will
not interfere with panel components. Install suite stations on
housings. Do NOT overtighten screws on plastic panels.
Connect power transformer primary to 117 VAC.
TEST AND CHECKOUT
At entrance panel, push each button. Check to determine if the
correct suite is buzzed each time. At each suite, pushTALK and
LISTENbuttons to communicate with someone at the entrance

OPERATION
1. VOICE VOLUME: is adjustable externally using a small screw-
driver through the port hole on the front of the PK-543
labeled “VOICE VOLUME”.
2. PROGRAMMING SWITCHES:
Switch #

#3
ENTRANCE TONE: call tone at entry panel is enabled with
the 3rd dip switch to the right, and disabled to the left.
#4
Not used.
1. Entire System Dead - Check 117
VAC at transformer primary, 16
VAC at transformer secondary,
and wiring to PK-543.
2. No Talk -Checkwiringto terminals
1and 2 shortedoropen,andwiring
to entrance panel speaker open or
shorted.Suitestationmaybetested
by replacement.
3. No Listen - Check wiring to termi-
nals 1 and 3 shorted or open and
short between terminals 1 and 2.
4. No Door Operation -Checkwiringto
door release shorted or open, de-
fective door release, and door but-
ton on suite station. Check wiring
to terminals 2 and 3, or 1 and E.
5. No Buzzing - Check wiring to
PK-543 terminal Z, or ZW, panel
push-buttons, and wiring to suite
stations terminal X.
6. Excessive Hum or Distortion Check
wiring installed too close to
electrical wiring or electrical
devices, PK-543 installed too
close to transformers or electrical
devices, twisted pair wiring not
used as required, or PK-543
volume set too high.
7. Radio Interference - Check
connection from the PK-543
terminal G to electrical ground.
Note:
This connection is not
shown on wiring diagram, since
the situation is not always
improved by adding it. If
problems persist, consult factory.
8. Oscillation -Checkwiringstep4on
page 1. If oscillation persists, con-
nect a model 15-MFD non-polar
capacitoracrossterminalsAandG
on the PK-543 amplifier.
Note:
Entrance Tone (if used) will
be lower with capacitor.
3. TONE VOLUME: is adjustable externally using a small screw-
driver through the port hole on the front of the PK-543
labeled “TONE VOLUME”.
NOTE:
Adjust Tone Volume to
maximum only when using PK-502B multi-entrance adaptor.
4. BUZZ 1: ZW terminal is a warble tone output.
5. BUZZ 2: Z terminal is a steady tone output. To be used for call
tone at suite station.
TROUBLESHOOTING
If the system fails to operate properly, check wiring. If wiring is
correct, check the following points:
NOTES: 1. USE #22 WIRE UNLESS SHOWN OTHERWISE.
2. IFTHEENTRANCEPANELHASAHANDSET,CONNECTIT
IN PLACE OF THE SPEAKER.
3. FOR DC DOOR OPERATION CONNECT DOOR RELEASE
TO L- (YELLOW) AND L+ (YELLOW/BLACK).
4. 3, 4 AND 5 WIRE STATION TYPES MAY BE USED IN ANY
COMBINATION,BUTNOTUSUALLYONTHESAMECABLE
RUN.
