1 DESCRIPTION AND SPECIFICATIONS
1.1 GENERAL DESCRIPTION
Telex has refined the look of multi-location security with the
WKP-1 industrial keypanel. It offers simplified operation
and integrates seamlessly with RTS™ digital intercom
systems (RTS™ ADAM™/ZEUS™ intercom systems). The
physical size and weather-resistant design provides a
flexible, robust intercom system. The GPI relay switch lets
the user set up door latching, unlatching and other related
actions by pressing a single button from any panel in the
system.
1.2 FEATURES
ENVIRONMENTAL:The unit sustains exposure to rain, snow, and
direct sun, allowing it to work in all environments. This
keypanel operates in temperatures ranging from -30° F to
120° F. The mechanical design of the aluminum front panel
and non-removable volume control knob, provide a vandal
resistant product.
GPI RELAY: The WKP-1 has a local GPI relay four-pin
terminal contact closure to give the user the functionality of
latching, unlatching doors or other related functions, with
the press of a button.
FRONT PANEL: Single button interface for push to talk
operation. There is a built-in water-resistant speaker for
listening capabilities. The panel has three LEDs used to
indicate Power ON, microphone (mic) ON, and Incoming
CallSignaling.
MICROPHONE:The WKP-1 has a built-in water resistant
Electret microphone. The microphone can be “hot mic”
enabled or disabled through the use of a dip switch setting.
KEY PANEL ASSIGNMENT: All key assignments, GPIO opera-
tion, and panel listen/muting functions are set through AZ
Edit™ software for the intercom matrix.
AUDIO CONTROL: The front panel volume controls adjust the
listen level to the internal speaker. An internal limit adjust-
ment sets the lower level of minimum volume achievable.
AUDIO PROCESSING: An integrallimiter/compressor insures
the maximum intelligibility of the spoken word. The
compressor uses the RTS™ standard compression design.
DUAL POWER: The keypanel can be powered locally through
the 3-pin terminal or remotely via a RJ45 connection from
the breakout panel or remote power supply.

2.1 Unpacking and Inspection
As soon as possible after receipt, inspect the container 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 involved and
file a claim. Save all packing materials, and request an immediate inspection by the carrier’s insurance claims agent.
The container should contain the following items:
1 WKP-1Industrial Keypanel
1 WKP-1User Manual
2.2 Installation and Mounting
The WKP-1 mounts directly into a standard two-gang electrical box. The electrical box must be at minimum 3 inches deep
to accommodate the stacked design of the pc boards (see figure 2).
3.0 DIP Switches
DIP Switch 1
Open: Default setting. Latching turned on.
Closed: Latching turned off.
Description: An intercom key can always be turned on for momentary conversation by pressing and holding the key
during the conversation.There is also an electronic latching feature that lets you tap intercom keys to turn them on or
off.This permits convenient hands-free conversation. However it can also result in a talk circuit being left on
unintentionally. For example, a key that talks to a public address system could be accidentally left on. Or an IFB key (a
type of key assignment that is often used by a security advisor to give instructions to a user) could accidentally be left
on, causing confusion for the listener.To prevent such accidents, the latching feature can be turned off.The latching
feature can also be turned on/off using AZ Edit software.
DIP Switch 2
Open: Default setting. 15 second flash after incoming call is received.
Closed: LED flash until caller releases key.
Description:Whenever there is an incoming call and there is a talk key assigned to the caller, the talk LED next to
that key will flash.The flash can be set for 45 second time-out, or until the caller's talk key is released.
DIP Switch 3
Reserved.LeaveOpen.
DIP Switch 4
Open: Default setting. The “hot mic” is disabled.
Closed: Audio from the built-in, water-resistant microphone leaves the panel at all times.
Description:When enabled, the audio will flow out of the key panel independent of the Talk key position.

WKP-1 Digital Matrix Intercom System Industrial Keypanel 9
4 Address Switch
A rotary switch is used to indicate the logical port address the key panel is to use when communicating with the Matrix.
The switch is read continuously through polling by the matrix. If the port address is changed, the new address is effective
immediately.
NOTE: The Address port, by default, is shipped with an invalid address to ensure that there are no conflicts with existing
keypanels. It is important to set the address port for the WKP-1 key panel for it to function properly.
☞In Zeus, ADAM CS, and ADAM intercom systems, intercom ports are arranged in groups of 8.Within each group,
each WKP-1 keypanel is uniquely identified by its Address switch setting.
The Address switch has a white pointer which points to the current switch setting. Determine the proper setting as follows:
Zeus Intercom Systems:
Intercom port connectors on the Zeus back panel are arranged in three groups of eight intercom ports.For each
group, intercom port connectors are labeled ID 1, ID 2, etc.When you connect an WKP-1 keypanel to Zeus, set
theWKP-1 Address switch to match the corresponding ID number on the Zeus back panel.Note, the address
switch settings 0, and 9 through F are not used.
ADAM CS Intercom Systems:
Each Audio I/O card contains 1 group of 8 intercom ports.However, the method of breaking out the groups
depends on the type of connectors on the back panel.To determine theWKP-1 Address switch setting, use the
planning work sheets in the ADAM CS Installation Manual.
ADAM CS with RJ12 back panel:You can determine the keypanel address from the work sheets 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
work sheet, then read across to the appropriate logical keypanel number for that port number.Use that number to
set the WKP-1 Address switch. 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 work sheet, then read across to the
appropriate logical keypanel number.Use that number to set theWKP-1 Address switch.
Note:The address switch settings 0, and 9 through F are not used.
ADAM CS frame with 50-pinTelco back panel:You can determine the keypanel address from the work sheet 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 work sheet, then read across to the appropriate logical keypanel number for that port number.Use that number
to set the WKP-1 Address switch.2) If you know the connector numbers and pin numbers that the keypanel will be
connected to, look up these numbers in the work sheet, then read across to the appropriate logical keypanel
number.Use that number to set the WKP-1 Address switch.
ADAM Intercom Systems:
Each Audio I/O contains 1 group of 8 intercom ports per card. However, the individual intercom ports may be
broken out using various types of breakout panels or punch blocks, and groups may not be easily identified. It
may be easier to set theWKP-1 Address switch using the actual intercom port numbers.To do this, refer to Table ,
page .Locate the intercom port number to which the WKP-1 will be connected.Then, read across to the “Address”
column to find the Address number.Set the WKP-1 Address switch to this number.Note: settings 0, and 9 through
F are not used.

10 WKP-1 Digital Matrix Intercom System Industrial Keypanel
The WKP-1 Industrial Keypanel is susceptible to a feedback squeal due to the placement of the the Mic in relation to the
Speaker. When this occurs a continuous audio loop forms which creates a feedback or squeal. For example, in Figure 3
audio enters the Mic in the WKP-1, goes to the Matrix, then out the speaker on the KP-32. If the Mic on the KP- 32 is ON,
the sound emitting from the speaker may be picked up by the mic and sent back to the matrix and to the Industrial
keypanel, thus creating an audio loop. However, if at some point within in that loop a break occurs, due to half duplex
mode or gain control settings, the loop cannot complete and the feedback is not heard.
There are several different ways to reduce audio feedback:
Change Gain Settings with the application setup:
There are several different points within the system setup where the user can set the gain control so as to limit
the Mic or Speaker sensitivity to reduce the occurance of feedback. The gain control can be modified in the WKP-
1, in the Matrix on the crosspoints (using AZedit) or in the keypanel on the other side of the matrix. For example, if
the purpose of the industrial keypanel is to overhear work being done in a warehouse, which may or may not be
close to the speaker, the sensitivity of the speaker must be set to pick up audio from a distance. And, since the
main use of the keypanel is to listen, the Mic gain control is set low not to allow the speaker pick up any audio.
For more information on how to set the gain control within theWKP-1, see page 11.
Run in Half Duplex Mode:
Half Duplex Mode allows the transmission of audio data in just one direction at a time, whereas full-duplex mode
allows transmission in both directions at the same time. Because the WKP-1 does not support Half Duplex Mode,
the half duplex mode must be setup on the keypanel at the other end of the transmission. By setting the keypanel
in half duplex mode, this forces a break in the audio feedback loop. In Half Duplex Mode the user can either listen
or talk, but not both at the same time.
These configurations are done in AZedit. Auto-reciprocal allows listen to be on all the time and allows talk to be
turned on and off. This reduces feedback because talk is only on when the talk button is pressed, therefore not
allowing audio through. Auto-Mute is also a way to reduce feedback through the system. When Auto-mute is
utilized, Listen automatically turns off when the Talk button is activated.
Talk Latch Disable:
Talk Latch Disable is another way in which the audio feedback can be reduced. Talk Latch allows the user to push
a keypanel button once andTalk is turned ON. WhenTalk Latch is disabled, the talk function only works when the
button is pressed. The user can disable the talk latch button through AZedit or set DIP switch 1 to close in the
WKP-1 DIP switch settings.

Figure 4. The middle board in theWKP-1 (also referred to as the audio board).
There are 3 gain control pots that can be configured to reduce feedback. By turning the gain control clocwise, increases
the gain level, turning it counter-clockwise, decreases the gain level.

5 Keypanel Setup
You can only assign keypanel assignments using AZ Edit. For more information on AZ Edit, see the AZ Edit Software
help.
5.1 Intercom Key Operation
Volume Adjustment
Adjust speaker listen volume with theVolume control.
Momentary vs. Latching Operation
For momentary key activation, press and hold an intercom key. For latching operation, tap the key to turn it on, and tap it
again to turn it off.
NOTES:
•If the LED next to a key does not turn on when the key it activated, this means the key is not currently assigned.
•The electronic latching feature (DIP switch 1) must be enabled in order to use latching. See Section 2 for details.
5.2 Intercom Key Operation for DifferentTypes of Key Assignments
BasicTalk or Listen Key Operation: The Push to Talk button activates talk (if assigned).Listen cannot be activated from
the WKP-1. The user can only listen when a different keypanel is talking to it.
NOTE: The following paragraphs describe special types of key assignments called special functions.These types of
key assignments can only be set up using the AZedit software. They are described in detail in the software help file.
To find out if a key has a special function assignment, you can display the key’s assignment as described under
“Displaying Key Assignments” in the AZedit online help.If a special function is assigned to a listen key, you will see
AF, or AL, etc.when you display the key assignment.
Talk+Auto-follow (AF) Listen Key Assignment:This key assignment works the same as the basic talk/listen key
assignment:The PushTo Talk button activates talk.Talk may be turned on or off independently by pressing and or
releasing this button.
Talk+Auto-listen (AL) Listen Key Assignment:The PushToTalk button activates both talk and listen.However, only the
talk LED will turn on. If talk is on, you cannot turn off listen. If talk is off, you can turn listen on independently by
pressingup.
Talk+Auto-reciprocal (AR) Listen Key Assignment:The PushToTalk button activates talk.Listen is always on and
continuously monitors whatever is assigned to the talk position.
5.3 Intercom Key Indications
Mic-On Indicator:
Solid green :Talk is activated.
Continuous red“in use” indication :An “in-use”indication is provided for an IFB key. It is also provided for a
key that talks to a remote intercom system (when your intercom system is equipped with optional trunking).The “in-
use” indication warns you that someone else is currently talking.
Red flashing “busy” indication : May occur when the Talk key is activated to talk to an IFB or a remote intercom
system. This indicates that some other keypanel with a higher priority is currently talking and you cannot talk at
this time. Calls have been answered, the green LED next to the call waiting key will turn off.

16 WKP-1 Digital Matrix Intercom System Industrial Keypanel
5.4 Incoming Calls
A Green flashing “incoming call”LED indication :This means another user on the intercom system is calling.To answer the
incoming call, depress the
PushTo Talk button.
The Mic-On or Call LED indicator flashes to indicate an incoming call to the keypanel.
•If Tally is disabled, the LED indicator is only enabled for 45 seconds before it stops and returns to normal
operatingmode.
•If Tally is enabled, the LED indicator is active for as long as the Push To Talk button is not depressed.
Note: If the
Push To Talk is enabled and disabled, the LED indicator reactivates itself.
When a call comes to the keypanel, the incoming call LED indicator is activated and flashes. At this point, if the Push To
Talk button is pressed, it acts as a CallWaitingWindow (CWW) reply key. The user can respond to the incoming call rather
than only being able to talk to the preassigned talk key.
There is a 45 second time out to reply to the incoming caller. Once the 45 second timeout has elapsed and the
PushTo
Talk
button is no longer depressed, the panel returns to normal operation.
Note:The 45 second time out does not mean that after 45 seconds the user cannot continue talking with the
incoming caller if the Push To Talk key is still pressed. It means that after 45 seconds if either the incoming caller
or the WKP-1 disconnects normalTalk key assignments are restored.
5.5 OperationWith theTIF-2000Telephone Interface
You can use the keypanel to answer incoming telephone calls that have been received by the TIF-2000. A talk and listen
key pair on the keypanel must be assigned to talk/listen to the TIF-2000 as previously described. Use the assigned keys as
follows:
1. Do not push the PushToTalk button, except when answering a call.
2. When there is an incoming phone call, the talk indicator flashes red. Press the Push To Talk button to talk back.
3. When the conversation is finished, release the button.
Important!: The keypanel does not hang up the phone line when you turn the keys off.The TIF-2000 does this by
detecting when the caller has hung up. However, this may not be possible in some phone systems, therefore, the
TIF-2000 may remain off hook. In this case you must manually disconnect using the OFF switch on the front of
theTIF-2000.
NOTE: Unless there is an incoming call to answer, activating a key on the keypanel that is assigned to the TIF-2000
will have no effect.
