installation methods.
2. Install housings (or boxes) and wiring.
3. Check wiring, connect and install equipment.
4. Apply power and check operation.
EQUIPMENT LOCATION AND
HOUSING INSTALLATION
Suite Stations
Locate suite stations where convenient for use. Install a
housing or back box at the desired location.
Entrance Panel
Use an OH190 and OF190 series housing and frame for
flush wall mounting. Use an OF190S series frame for
surface mounting. Locate the entrance panel where it is
sheltered from the weather.
Amplifier
Install the amplifier inside the entrance panel when using
an OH190 series housing. The amplifier must be installed
outside the entrance panel when using an OF190S series
surface frame. Refer to Connections Section, Item #3 for
further details.
WIRING
Suite Stations
Stations may be connected in risers as shown in the wiring
layout diagram, Figure 1. Each riser requires one twisted
pair #22 (or as required for type of station), plus one
conductor #22 for each suite served by the riser. (Run an
additional 2 #22 conductor for LED circuit when using
IR104C/LEDor IR204C/LED stations.) Maximum length
is 400 feet (120 meters). Additional risers may be added
as needed. Cable should not be run in the same conduit
with (or too close to) electrical wiring, background music
wiring,orveryclosetofluorescentlightsorotherelectrical
equipment. Leave sufficient cable in each back box to
make connections. Do not cut cable at each station.
Transformer
Wiring must be 2 conductor, #18. Maximum cable length
is 80 feet (25 meters), or up to 200 feet (60 meters) using
#14 wire. Route cable away from suite station wiring.
Door Release
Wiring must be 2 conductor, #18 cable. Maximum length
is 50 feet (15 meters). To use 24 volt door release, use a
TekTone® SS106 Transformer and connect as in Figure 2.
CONNECTIONS
Before connecting, make certain wires are free from shorts
or grounds. Make connections as shown in Figure 3,
observing the following notes:
1. Do not apply power to transformer primary until entire
system has been installed and all wiring checked for
shorts or grounds. The common wires connecting to
terminals 1, 2, 3, E and 5 should show open circuit when
tested with an ohmmeter.
2. Use twisted pair wiring as shown. Do not interchange
wires or reverse polarity.
3. Install PK543 amplifier inside the entrance panel when
using OH190 Series Housing. If it is necessary to install
the amplifier elsewhere due to temperature extremes, or
becausean OF190S Surface Frame is being used,or if an
AM600 Panel is being used, then 2-conductor, shielded
cable must be used for the entrance panel speaker wiring

TROUBLESHOOTING
Ifthesystemfailsto operate properly, checkwiring.Ifwiring
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
doorrelease,anddoorbuttononsuitestation.Checkwiring
to terminals 2 and 3 or 1 and E.
No Buzzing
CheckwiringtoamplifierterminalZ, or ZW entrance panel
push buttons; and wiring to suite station’s terminal X.
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
improvedby adding it. If problems persist, consult factory
or service representative.
Oscillation
Reduce VOICE VOLUME until oscillation disappears. If
oscillationdisappearswhenthe buzz wire is removed from
terminal ZW(red/white), set the ENTRANCE TONE switch to
the off position, or use terminal Z for the buzz push button
connection.

SIGNALFLOWANDTHEORYOFOPERATIONFOR
PK543 AMPLIFIER AND APARTMENT INTERCOM SYSTEM
The following example describes an Apartment Intercom
System using a PK543 Amplifier and is based on a 4-Wire
Intercom Station.
Call Button
PressinganapartmentCALL buttonontheentrypanelroutes
the call tone from the PK543 Amplifier’s terminal ZW
(or Z), through the apartment button being depressed, to
theTone In (X) terminal on the apartment intercom station
being signaled. This tone passes through the intercom
station’s speaker and returns on Common (1). The tone is
heard at the intercom station—and if dipswitch 3 is in
the ON position—at the entry panel. (Applies to warble
tone only.)
Talk Button
Pressing the TALK button at an apartment intercom station
connectsaudiofromtheintercomstation’sspeakerthrough
the intercom station’s terminals 1 and 2, to the PK543
Amplifier’s terminals 1 and 2. This audio is amplified and
outputon the amplifier’s terminalsAand G.The amplified
audio is then routed to entrance panel’s speaker/
microphone. The result is that someone speaking at the
apartment intercom station is heard at the entrance panel.
In 3-wire apartment intercom stations, audio to and from
the intercom station is between terminals 1 and 5.
Listen Button
Pressing the LISTEN buttonatanapartmentintercomstation
connects the speaker of the intercom station to terminals
1 and 3 of the PK543 Amplifier, which outputs amplified
audio from the entrance panel speaker. The entrance panel
speaker remains connected to the PK543 amplifier
terminals A and G, and acts as a microphone in this mode.
In 3-wire apartment intercom stations, audio to and from
the intercom station is between terminals 1 and 5.
Door Button
Pressing the DOOR button at an apartment intercom station
applies a closure across the intercom station’s terminals 2
and 3. The closure is routed to the PK543 Amplifier’s
terminals 2 and 3. The amplifier senses the closure and
provides 16 VAC across the amplifier’s terminals D and
K. At the same time, DC voltage is also present across
terminals L+ and L- as the unfiltered output of a full-
wave rectifier fed by the same 16 VAC.This voltage is
applied to the door release to unlock the entrance door.
There are two possible variations of this scheme. First, a
closure across PK543 Amplifier’s terminals 1 and E can
be used to output 16 VAC across the amplifier’s terminals
D and K. Second, pressing the DOOR button at a 5-wire
apartment intercom station produces a closure across
the intercom station’s terminals 1 and E (terminal 4).
Door Ajar Indication
This feature is available with the IR104C/LED and
IR204C/LED suite stations. When the door is open and
the door contact is in the closed state, the DOOR button’s
LED will illuminate to indicate the door is ajar.
Post Office Lock
Actuating the post office lock applies closure across the
PK543 Amplifier’s terminals 1 and E (terminal 4). The
PK543Amplifier senses the closure, and outputs 16 VAC
across the amplifier’s terminals D and K. At the same
time, DC voltage is also present across terminals L+ and
L- as the unfiltered output of a full-wave rectifier fed by
the same 16 VAC. This voltage is applied to the door
release to unlock the entrance door.
