2 INSTALLATION
2.1 GENERAL
Installation consists of the following general steps:
1. Unpack and inspect the equipment.
2. Check that the factory default jumper positions and
level settings are appropriate for your application and
make any required changes. (The defaults are
virtually always acceptable.)
3. Set the back panel DIP switches.
4. Mount the keypanel and any expansion panels in an
equipment rack or bay.
5. Connect the keypanel and any expansion panels.
6. Power up the equipment and check operation.
7. Program the keypanel using the intercom system
configuration software (ADAMedit or ZEUSedit).
2.2 UNPACKING AND INSPECTION
As soon as possible after receipt, inspect the container(s)
and contents for physical damage that may have occurred
in shipping. If damage has occurred, immediately (within
24 hours of receipt of equipment) contact the carrier in-
volved and file a claim. Save all packing materials, and
request an immediate inspection by the carrier’s insurance
claims agent.
There should be one power cord for each keypanel and
one gooseneck microphone for each keypanel ordered
with a microphone. There should be one power cord and
one interconnect cable for each expansion panel.
☞For information about returns to RTS, refer to the
front of this manual.
2.3 CHECKING THE FACTORY JUMPER AND
LEVEL SETTINGS
There are several internal jumpers and level adjustments
which can be changed to modify the keypanel operation
and audio input/output levels. These have been set to meet
the requirements of most typical situations. However, if
you wish to review these settings prior to installation, re-
fer to “Electrical Adjustments”, page 12.
2.4 DIP SWITCH SETTINGS
The DIP switches are located on the back of the keypanel.
The switch settings are summarized in Table 1and are de-
scribed in the following paragraphs.
☞Important: Any time you change the DIP switch
settings you must turn the power off-then-on to reset.
2.4.1 Logical Keypanel ID Selection
DIP switches 4-7 set the logical keypanel ID, which
uniquely identifies the keypanel in the intercom system.
Zeus Intercom Systems: The logical keypanel ID’s are
the numbers ID1 through ID8 printed on the back panel of
the Zeus frame next to the keypanel connectors. (The
numbers repeat for every group of 8 connectors.) As you
connect each keypanel to a connector, use the number
printed next to that connector to set the ID. For example,
if you connect a keypanel to a connector numbered ID1,
refer to Table 1and set DIP switches 4 through 7 to select
ID1.

Table 1. DIP Switch Summary

ADAM CS Intercom Systems: Use the appropriate plan-
ning worksheet in the ADAM CS Installation Manual.
(Refer to the List of Tables in the front of the manual. The
planning worksheets are listed at the bottom of the List of
Tables.)
•ADAM CS with RJ-11 or DB-9 back panel: You
can determine the correct logical keypanel ID from
the worksheet in either of two ways: 1) If you know
the port number that a keypanel will be connected to,
look up the port number in the worksheet, then read
across to the appropriate logical keypanel number for
that port number. 2) If you know the connector
number (on the back of the ADAM CS frame) that
the keypanel will be connected to, look up that
connector number in the worksheet, then read across
to the appropriate logical keypanel number.
Once you have determined the correct logical
keypanel number, refer to Table 1and position DIP
switches 4 through 7 to set this as the ID.
•ADAM CS frame with 50-pin Telco back panel:
You can determine the correct logical keypanel ID
from the worksheet in either of two ways: 1) If you
know the port number that a keypanel will be
connected to, look up the port number in the
worksheet, then read across to the appropriate logical
keypanel number for that port number. 2) If you
know the connector numbers and pin numbers that
the keypanel will be connected to, look up these
numbers in the worksheet, then read across to the
appropriate logical keypanel number.
Once you have determined the correct logical
keypanel number, refer to Table 1and position DIP
switches 4 through 7 to set this as the ID.
ADAM Intercom Systems: To set the ID, first refer to
Table 8, page 18, and locate the intercom port number to
which the keypanel will be connected. Then, read across
to the “ID” column to find the logical keypanel ID (it will
always be a number between 1 and 8). Finally, refer to Ta-
ble 1and set the DIP switches to this ID number.
2.4.2 Baud Rate
Dip switch 8 selects the baud rate for communication with
the intercom system’s configuration computer. For all
ADAM, ADAM CS, and Zeus intercom systems this
switch must be set to the open position (9600 baud). Do
not use the 76.8 kbaud setting.
2.5 MOUNTING THE KEYPANEL AND
ACCESSORIES
Keypanels and expansion panels may be mounted in any
industry standard 483 mm (19") wide equipment rack or
equipment bay. For all panels, allow an additional 2 to 3
inches in back for cables and connectors. No special tools
other than those found in a typical tool kit are required for
mounting. The panels have no special ventilation require-
ments.
2.6 STANDARD CONNECTIONS
☞For additional connection information, see page 10.
2.6.1 Gooseneck Microphone
If you ordered the keypanel with a gooseneck micro-
phone, screw the microphone into the panel microphone
jack on the front panel.
2.6.2 Connection To Intercom Matrix
Use either a 9-pin or RJ-11 intercom cable (but not both)
to connect to the intercom system. You can use a prefabri-
cated cable, or construct a cable using the wiring diagram
in Figure 3or 4. Plug one end of the cable into the P10 or
P11 connector on the back panel of the keypanel. Plug the
other end into the appropriate port of the intercom system.
(This will be the port number that you designated previ-
ously when setting the logical keypanel ID.)
☞Keypanels may be connected while the intercom
system is running.
☞Note that 9-pin intercom cables for use with an
ADAM CS frame must use special connectors at the
intercom matrix end as shown in Figure 3.
2.7 KEYPANEL PROGRAMMING
If you previously configured the keypanel using the inter-
com system configuration software, it should be ready for
operation. Refer the station operator to the Keypanel Op-
eration instructions in the KP95-0 Operating Instruction
Manual.
If the keypanel has not yet been configured you can do so
now. Run the ADAMedit or ZEUSedit configuration soft-
ware. By default, the configuration software starts up in
the “Keypanels / Ports” setup screen. For assistance with
keypanel setup, press the F1 key on the computer while
viewing that screen. Once you have configured the key-
panel as instructed and sent the changes to the intercom
Installation Instructions, KP95-0 Keypanel 9

system, the keypanel should be ready for operation. Refer
the station operator to the Keypanel Operation instruc-
tions in the KP95-0 Operating Instruction Manual.
2.8 PRINTING DESIGNATION STRIPS
Designation strips can be printed for configured keypanels
by using the ADAMedit or ZEUSedit software. You can
insert the strips into the designation strips holder on the
front panels of keypanels and expansion panels to label
the keys with their assigned destinations.
This completes the standard installation procedures.
2.9 OPTIONAL CONNECTIONS
2.9.1 Expansion Panels
Figure 5shows optional interconnections when using ex-
pansion panels with the keypanel. Use the cables provided
with the panels. Connect a maximum of three EKPD-95
expansion panels to the KP95-0.
2.9.2 Rear Panel Headset Connection
Table 4lists the HEADSET connector pin functions. A
variety of headset types can be connected. Head-
set/speaker switching can be accomplished from this con-
nector. Shorting pins 7 and 8 will cause the headset to
activate, and the front panel speaker and microphone will
turn off.

2.9.3 Terminal Block Connections
(Reference Figure 6)
AMP OUT + and - : These terminals provide the key-
panel audio amplifier output signal to drive an 8-ohm, 3-
watt speaker. As supplied from the factory, jumpers con-
nect these terminals to the SPKR IN + and - terminals.
Remove these jumpers only if the keypanel audio output
is to be redirected to an external speaker.
SPKR IN + and - : These terminals connect to the inter-
nal speaker.
GRP CALL (Group Call): As supplied from the factory,
a jumper connects this terminal to the ground terminal for
normal Talk key operation. For external group call, re-
move the jumper, and connect a normally open foot
switch between this terminal and the ground terminal.
When the foot switch is pressed, all Talk keys that are
latched in the up position will be activated. When the foot
switch is released, they will be deactivated.
EXT MUTE: This terminal may be used to drive an ex-
ternal device at no greater than 2 mA sinking current. Its
normal logic state is low (0 Vdc). It shifts to logic high
(+5Vdc) when any Talk key is pressed. This signal may
be used, for example, to mute a monitor speaker when the
keypanel operator is talking on the intercom system.
2.9.4 EXT MIC IN Connector
An external microphone can be connected. The external
microphone may be used with or without a front panel
gooseneck microphone of the same type. (Internal key-

panel jumpers J404-J406 must be set for the type of mi-
crophone (see "Internal Jumpers", page 12).
2.9.5 EXT LINE IN Connector
An external balanced audio source, such as program
sound, can be connected. The input is calibrated for a
nominal line level of +8dBu. This level can be changed if
required. See "Line Input to Speaker Level Adjustment",
page 16, for further information.
2.9.6 MIC PRE OUT Connector
This connector provides a balanced mic output signal of
+8 dBu at 60 ohms. As supplied, the MIC PRE OUT sig-
nal is activated only when any Talk key is on. If you want
this output to be on continuously, you must reset internal
jumper J403 (see "Internal Jumpers", page 12).
2.10 POWER-UP AND OPERATIONAL CHECK
Plug in the AC power cords on the keypanel and expan-
sion panel, if used. Assign a talk key to a crosspoint using
the configuration software, and place calls to and from the
keypanel.
The following symptoms may occur if the logical key-
panel number is incorrectly set: 1) when a key is pressed
to talk, the destination may not hear the audio, or may
hear audio from a different intercom station, or 2) there
may be no audio received when a call is placed to the key-
panel. If these symptoms occur, recheck the logical key-
panel number DIP switches.
☞Important! Always reset the keypanel after changing
the DIP switch settings. Do this by briefly removing
power to the keypanel.
3 ELECTRICAL ADJUSTMENTS
3.1 INTERNAL JUMPERS
There are several internal jumpers which modify keypanel
operation. The jumpers are set for the following default
operations:
J201: The EXT LINE IN signal is muted when any Talk
key is pressed. May be optionally set for no mute.
J202: The speaker (or headphones) are muted by 15 dB
when any Talk key is pressed. May be optionally set to
full mute.
J203: Continuous sidetone. When using a headset, the
keypanel operators own voice will be heard at all times in
the headphones. May be optionally set for sidetone only
during talk.
J401: The microphone activates when any Talk key is
pressed. May be optionally set for continuous micro-
phone.
J402: Normal/test switch set for normal operation.
J403: The MIC PRE OUT signal is activated only when
any Talk key is pressed. May be optionally set for con-
tinuous operation.
J404-J406: The keypanel is configured for operation with
the standard dynamic, -70dB, 150-ohm gooseneck micro-
phone. May be optionally configured for other micro-
phone types.
To reset any of the jumpers, remove the top cover from
the keypanel. Locations of the jumpers are shown in Fig-
ure 7. The following paragraphs describe the alternative
settings for the jumpers.

3.2 AUDIO LEVEL ADJUSTMENTS
3.2.1 GENERAL
The following paragraphs describe the procedures to cali-
brate the output level to the factory standard of +8 dBu. If
a different level is required, substitute that level for +8
dBu.
Most audio level trimmers are accessible through access
holes on the back of the keypanel. Each trimmer access
hole is labeled with its function. Some trimmers are inter-
nal, and can only be accessed with the top cover removed.
Locations of trimmers are shown in Figure .7
Audio levels may be adjusted with the panel disconnected
from the intercom system. However, proper operation
should be confirmed when the panel is reconnected. If
levels change after reconnection, check the intercom sys-
tem wiring for one-sided shorts to ground, wiring errors,
or unintended terminations.
Connector pin-outs for these connectors were presented
earlier in this section. If the keypanel under adjustment
does not have these connectors, refer to drawing number
IKP-950/2-5 (in the Keypanel Drawings and Parts Man-
ual). The IKP-950/2-5 drawing shows equivalent locations
where test equipment may be connected.
Required test equipment:
Audio Signal Generator with balanced output
Audio Signal Analyzer with balanced input
DC Millivoltmeter
Oscilloscope - any commercially available type
3.2.2 MICROPHONE PREAMPLIFIER
1. Set the HDST switch to off.
2. Remove the gooseneck microphone, and insert a -70
dBm signal (1KHz at 150 ohms) into the microphone
connector. Or use the EXT MIC IN connector with
the front panel microphone removed (ref Table 7,
page 12 for pin-out).
3. Activate the microphone by setting a Talk key to the
latched-up position.
