INSTALLATION FOR WALL MOUNTING
1) Attach the mounting bracket to wall or plaster ring.
2) Remove the rubber feet from base of station.
3) To attach the provided handset cradle, remove two
screws, place the cradle and reinsert the two screws.

INSTALLATION OF TERMINAL BOX
1) Remove screws and cover as shown.
2) Attach bottom case to wall or 1-gang box.
3) Replace cover after wiring.
Please refer to the labels
on the sides of terminal
box and back of the cover.
WIRING’ Use straight conductor cable. Do not use twisted pairs. TERMINAL IDENTIFICATIONS
Lay out your system in advance. Determine the exact location of each station. We recommend a full complement
of wire be installed, even though you may not initially be installing the maximum number of stations available to your
system. This way, should you decide to add a station later, you can avoid running additional cables to existing stations.
Connect wires to terminals 01 & 02 if wire distance exceeds 200m (600’) total or more than 13 stations are used in your
KAH system.
Refer to the chart below and select the proper wire gauge to meet your requirements.

Referring to the diagram which illustrates your system, write your color code in the space privided. Begin your
installation with station #1. Note the position of the C terminal at each station. Be sure you wire each station correctly.
After installing the second station we recommend that the power supply be connected to the + and — terminals on
a phone and that a test be made for calling and talking between the stations. As each additional station is installed retest
between each station. Unplug power supply while making wiring connections.

CONNECTION OF PA-1 BLOCK PAGING ADAPTOR
1) Extend conductors from the phone network plus (+), minus (—) and an unused number terminal to
plus (+), minus (—) and C on the PA-1.
2) Using shielded cable, connect the background music source to terminals M and G on the PA-1.
3) Using shielded cable, connect terminals A and G on the PA-1 to the AUX (or PROGRAM) input of
the paging amplifier.
Each PA-1 provides a separate block and channel for paging.
AMPLIFIER REQUIREMENTS
* Input:
* Output:
AUX; more than lOK ohm, —10 dbm..
Less than 100 watt RMS with either 25, 70 or 100 volt line.
BACKGROUND MUSIC REQUIREMENTS
* Use audio output: RANGE; 100 mV — 1.2 V, 600 ohm — lOK ohm.
CONNECTION OF PA-2 BLOCK PAGING ADAPTOR WITH TALKBACK
1) Extend conductors from the phone network plus (+), minus (—) and an unused number terminal to
plus (+), minus (—) and C on the PA-2.
2) Using shielded cable, connect the background music source to terminals M and G on the PA-2.
3) Using shielded cable, connect terminals A and G on the PA-2 to the AUX (or PROGRAM) input of
the paging amplifier.
4) Connect the output of the amplifier 25, 70 or 100 volt line to terminals V, V on the PA-2.
5) Connect speakers to terminals SP on the PA-2.
Each PA-2 provides a separate block and channel for paging with talkback.
AMPLIFIER REQUIREMENTS
* Input:
* Output:
AUX; more than lOK ohm, —10 dbm.
Less than 100 watt RMS with either 70 or 100 volt line.
Less than 60 watt RMS with 25 volt line.
BACKGROUND MUSIC REQUIREMENTS
* Use audio output: RANGE; lOOmV—1.2V, 600 ohm—lOK ohm.
NOTE:
Due to line induction, TALKBACK paging noise control and volume adjustments become more difficult
as the line distance increases. Short wiring distances between the amplifier/PA-2 and the paging speakers
provide the best talkback paging and the best control. To assure the best possible talkback paging
system, we recommend a talkback speaker line consisting of shielded 2-conductor cable.

INSTALLATION OF BLOCK PAGING ADAPTOR PA-1
This example illustrates connection if block paging is desired but without talkback. One phone must be deducted
from the system for each block. Each block requires one PA-1 and one paging amplifier. In this example selector button

COMBINATION OF STRAIGHT PAGING AND TALKBACK PAGING
DUE TO THE ADVANCED DESIGN OF THE PA-1 AND PA-2 BLOCK PAGING ADAPTORS, SEPARATE
CHANNELS MAY BE ESTABLISHED FOR PAGING OR PAGING WITH TALKBACK TO ANY NUMBER OF BLOCKS.
1) One potential phone must be deducted for each PA-1
or PA-2 installed.
2) One amplifier must be used with each PA-1 or PA-2.
3) Only one background music source, if used, is required
for entire system.
This example shows one area of talkback paging (block #1)
and two areas of paging without talkback (block #2 and
#3).
Selector button #10 on each phone operates block #1,
selector button #11 operates block #2, and selector
button #12 operates block #3.

OPERATION
Calling;
Lift the handset and depress the selector button desired to communicate with, then momentarily depress the C button.
This will sound a single stroke chime which indicates that the connection has been established.
1) If you hear a repeated tone, it means that the called station is switched for the privacy position. Wait for an answer
or call later.
2) If you hear a continuous tone, it means that the called station is in the Line privacy position. Please call later.
3) If you hear no tone, it means that the called station is busy. Please call later.
4) If you hear a conversation, it means that the called station is in open voice communication.
* If the noise level at the called station is high, you may increase the output by using the P button, press to talk release
to listen.
Receiving;
When your station is in non-privacy position, an incoming call is announced by single stroke chime and a call lamp.
A reply can be made hands free using loudspeaking microphone or privately by using the handset.
When your station is switched for the privacy, an incoming call is announced by a repeated tone and a call lamp.
A reply can be made by using the handset or by unlocking the privacy button and conversing handsfree.
When your station is switched for the Line privacy, an incoming call is announced only by the call lamp. The calling
station understands that you are not in a position to reply and will cancel his call.
Adjusting privacy tone volume;
A volume control is provided on the rear of the unit to adjust the privacy tone volume. Adjust as desired.
TELEPHONE STATION KAH-2 OPERATION
The telephone station KAH-2 is equipped with 2 station selector buttons, a call button and a P button. It can place
calls to two speaker phone master stations as selected upon installation. The KAH-2 can receive a call from any speaker
phone station. Operation of the KAH-2 is the same as the speaker phone stations but reply can be made only by using the
handset.
PAGING OPERATION
If appropriate equipment is installed, select the zone you wish to page and momentarily depress the C button to
establish the channel. Use the P button for press to talk (and if PA-2 is used, release to listen). Background music will
be automatically cut off.
