EB8E4A Functions & configuration
1.0/0315 9
Functions & configuration
Basic settings
When the option module EB8E4A is connected to an Intercom module and therefore linked with an In-
tercom Server, the server identifies the EB8E4A automatically. A green LED on the top of the EB8E4A
shows the status of the option module:
Very fast blinking (125 ms): No configuration available (factory setting).
Fast blinking (250 ms): Configuration available, offline mode.
Normal blinking (625 ms): Configuration available, online mode.
After the server configuration is read out via the configuration software CCT 800, the EB8E4A will be
shown as sub-folder in the respective Intercom station folder at Subscriber > Station properties.
Indication of the EB8E4A in the respective Intercom module sub-folder in CCT 800.
Inputs and outputs
The EB8E4A has eight digital inputs and four relay outputs. With that, it complements the existing con-
nections on an Intercom module, e.g. to connect additional switches, push buttons, etc. The relay out-
puts “OUT1” as well as “OUT2” are designed as NO contacts and “OUT3” as well as “OUT4” are de-
signed as changeover contacts.
The eight digital inputs can be used for all features, which are shown at Subscriber > Station
properties > EB8E4A. Three inputs (“IN1” to “IN3”) of them are available for additional features,
e.g. for input messages or dialling simulations. These three inputs can be linked with the screw ter-
minals from “E1” to “E8”.
The four relay outputs can be used for all features within or outside the folder EB8E4A.
Attention:
If the configuration of the outputs differ from the offline functions, switching errors may occur. E.g. if
“OUT1” that is assigned for the call lamp in offline mode is connected to a door opener, the door opener
will be triggered by a call. For further information, see ”Offline output configuration” on page 20.
Notes:
The virtual inputs, which are named “E1” to “E8” in CCT 800, correspond with the physical screw ter-
minals, which are labelled “IN1” to “IN8” on the EB8E4A. These inputs have to be distinguished from
the simulated inputs, which are named “IN1” to “IN3” in CCT 800.
The virtual outputs, which are named “A1” to “A4” in CCT 800, correspond with the physical screw ter-
minals, which are labelled “OUT1” to “OUT4” on the EB8E4A.

Functions & configuration EB8E4A
10 1.0/0315
For using inputs and outputs for features outside the folder EB8E4A, they have to be activated first.
Therefore, carry out the following configuration in CCT 800:
Select Subscriber > Station properties > ET808 family > EB8E4A.
Activate the required connections in the fields IN1 to IN3 as well as OUT 1 to OUT 4 in the respec-
tive tabs Inputs and Outputs. Change, if required, the call numbers for the associated connections
next to the activated field.
Insert the first input and output numbers manually. By activating inputs and outputs, CCT 800 as-
signs the subsequent numbers automatically.
Input functions
Input simulation
The eight physical inputs “E1” to “E8” on the EB8E4A can be linked with the three inputs “IN1” to “IN3”
in the configuration software CCT 800 in any order. Thus, e.g. for input messages or dialling simula-
tions, the physical input “E1” on the EB8E4A can be linked with the input “IN1” on the ET 808A.
Carry out the following configuration in CCT 800 to link physical inputs with virtual inputs:
Select Subscriber > Station properties > ET808 family > EB8E4A > tab Inputs.
In the respective field, activate the desired input (“IN1” to “IN3”).
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Inputs /
Outputs > tab Input simulation.
In the drop-down list Simulated input no., define the desired input (“IN1” to “IN3”).
In the drop-down list Simulated level at active input, define the level that is processed in the In-
tercom Server at an active input (“Short”, “1k5”, “5k6”, “15k”, “Break”).
In the drop-down list Simulated level at inactive input, define the level that is processed in the
Intercom Server at an inactive input (“Short”, “1k5”, “5k6”, “15k”, “Break”).
Define which function the Intercom Server has to carry out, when the specified input level is detected
(e.g. input message or dialling simulation). For further information, see Manual “PRO 800 Basic”.
Switch contacts
Each of the eight inputs “E1” to “E8” on the EB8E4A can switch one of the four outputs “A1” to “A4”.
Carry out the following configuration in CCT 800 to switch an output via an input:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Inputs /
Outputs > tab Attendant contacts.
In the drop-down list Attendant contacts, define whether the terminal output should be turned
“on” or “blinking”.
In the drop-down list Output no., define which output has to be switched (“A1” to “A4”).
Attention:
If an output is already assigned to a function, the selection of an other function will overwrite the existing
configuration.
Note:
Per cell terminal, only three inputs can be configured – e.g. for input messages. This means: If one or more
inputs of the EB8E4A are in use (“IN1” to “IN3”), the respective inputs of the ET808A are no longer avail-
able.

EB8E4A Functions & configuration
1.0/0315 11
Inversion of inputs
Each input („E1“ to „E8“) of the EB8E4A can be inverted. Therefore, the state “Short” will be processed
as idle state and the previously defined action will be carried out at “Open”.
Carry out the following configuration in CCT 800 to invert inputs:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > tab Gen-
eral settings.
Activate the checkbox Inverted for the respective input (“E1“ to “E8“).
Input de-bounce time
For each of the eight inputs “E1” to “E8” on the EB8E4A, it is possible to adjust a de-bounce time.
Therefore, a period can be defined in which a signal has to be present at one input in order to be de-
tected from the system.
Carry out the following configuration in CCT 800 to set an input de-bounce time:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > tab Gen-
eral settings.
In the drop-down list Input de-bounce time [ms], define the de-bounce time in milliseconds (“16”,
“64”, “256” or “1024”).
Repetition lock for inputs
For each of the eight inputs “E1” to “E8” on the EB8E4A, it is possible to activate a repetition lock.
Therefore, a time interval can be defined in which only a certain number of calls can be initiated to pre-
vent repeated calls.
Carry out the following configuration in CCT 800 to activate a repetition lock:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > tab Gen-
eral settings.
In the drop-down list Interval [s], define the desired time interval in seconds (“1”, “2”, “4”, “8”,
“16”, “32”, “64” or “128”).
In the field Repetition lock, define the interval after which a new call can be initiated. Here, the fol-
lowing options are available:
“Interval must elapse each time”: After each initiated call (or any other defined action), a time in-
terval must elapse before a new call can be initiated.
“Interval must elapse each 2nd time”: Two calls can be initiated in a row. In this case, only two
calls can be initiated per beforehand-defined time interval.
“Interval must elapse each 4th time”: Four calls can be initiated in a row. In this case, only four
calls can be initiated per beforehand-defined time interval.
Example: In the following scenario, the configuration “Interval must elapse each 4th time” with a time
interval of 16 seconds was chosen.
Within of 16 seconds, four calls have been initiated:
There is a need to wait until 16 seconds have elapsed to initiate four calls again.

Prison cell call & officer emergency call
Definition of a call request
For the cell terminal, it is possible to define two desired call buttons (0to 9) for the call request to the
control desk (inquiry station) – one button for the type “call 1” and one button for the type “call 2”. The
required call buttons and surface sensors must be connected to the inputs of the EB8E4A. In this way,
you can simulate one of these buttons or initiate a call. For the indication of calls, e.g. by a lamp in the
aisle, it is possible to define attendant contacts. For further information regarding the attendant con-
tacts, see ”Prison cell call.
Prison cell call
The call is initiated by pressing the call button, which is connected to an input (“E1” to “E8”) at the
EB8E4A. Depending on how the prison cell is equipped, the call button can be designed as sensor but-
ton or as short-stroke button.
As acknowledgement for the prisoner, the cell lamp of the cell terminal is set to blinking. In the aisle,
the cell call is indicated by switching on the cell lamp. If required, it is also possible to switch on some
further group lamps or direction lamps.
In order to prevent repeated cell calls, it is possible to define a “Repetition lock”, so that there is no
chance to initiate a new call e.g. for 30 seconds after three calls had been initiated in a row. For further
information, see ”Repetition lock for inputs” on page 11.
The system indicates cell calls as normal calls with a long buzzer interval. The cell call can be cancelled
either by answering the call (building up a conversation) or by the attendance function (see ”
Attendan-
ce function” on page 14).
Carry out the following configuration in CCT 800 to enable prison cell calls:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Prison
cell call with officer emergency call > tab Prison cell call with officer emergency call.
In the drop-down list Prison cell call with officer emergency call, choose the option “Prison cell
call”.
In the drop-down list Simulated button at active input, define the button that is set for “call 1”
to the control desk.
Define an attendant contact for call requests to switch on the cell lamp. For this, activate the internal
output of the EB8E4A at Subscriber > Station properties > ET808 family > EB8E4A.
Activate the field Quittierung offline if an offline acknowledgement of a cell call is required.
Note:
In the system, “call 1” is a call request (cell call) and “call 2” an emergency call (officer emergency call).
Emergency calls have a higher priority than call requests. For further information regarding the indication
of calls in the aisle, see ”Light control in front of the cell” on page 18.

EB8E4A Functions & configuration
1.0/0315 13
Officer emergency call
At activated “attendance”, an officer emergency call will be initiated when the call button is pressed.
At inactive “attendance”, the system ignores the call. The call button has to be connected to one input
(“E1” to “E8”), in contrast the key switch has two switching positions (“attendance 1” and “attendance
2”) and has to be connected to two inputs (“E1” to “E8”). In addition, the officer emergency call can be
initiated automatically by an elapsed time when “attendance 2” is activated. For further information
regarding attendance, see ”
Attendance function” on page 14.
The system indicates officer emergency calls as emergency calls with a short buzzer interval. If “cancel
on site” is defined for the officer emergency call, the call is not cancelled after it had been answered
(building up a conversation). Instead of that, the system acknowledges the receipt of the call and turns
the buzzer signal off. The officer emergency call can only be cancelled by the “attendance function”
(see ”
Attendance function” on page 14). But this is only possible after the call had been acknowledged
from the inquiry station.
Carry out the following configuration in CCT 800to activate the function “officer emergency call”:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Prison
cell call with officer emergency call > tab Prison cell call with officer emergency call.
In the drop-down list Prison cell call with officer emergency call, choose the option “Officer
emergency call”.
In the drop-down list Simulated button at active input, define the button that is set for “call 2”
to the control desk.
Define an attendant contact for switching the cell lamp at call requests. For this, activate the internal
output of the EB8E4A at Subscriber > Station properties > ET808 family > EB8E4A.
Activate the field Quittierung offline if an offline acknowledgement of a cell call is required.
Define the functions of the key switch. For further information, see ”
Attendance function” on
page 14.
Prison cell calls with officer emergency calls
Prison cell calls and officer emergency calls can also be combined at one input. At inactive “attend-
ance”, the system cancels standard cell calls, and at active “attendance”, the system initiates an officer
emergency call.
Carry out the following configuration in CCT 800 to activate the function “prison cell calls with officer
emergency call”:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Prison
cell call with officer emergency call > tab Prison cell call with officer emergency call.
In the drop-down list Prison cell call with officer emergency call, select “Prison cell call with
officer emergency call”.
In the drop-down list Simulated button at active input, define the button that is set for “call 1”
to the control desk.
Define an attendant contact for switching the cell lamp at call requests. For this, activate the internal
output of the EB8E4A at Subscriber > Station properties > ET808 family > EB8E4A.
Activate the field Quittierung offline if an offline acknowledgement of a cell call is desired.
Define the functions of the key switch. For further information, see ”
Attendance function” on
page 14.
Note:
If “Prison cell call with officer emergency call” was configured, “Officer emergency call” has to be config-
ured with another input. This means: For the button with “Call 1”, “Prison cell call with officer emergency
call”, and for the button with “Call 2”, “Officer emergency call” have to be configured – otherwise the “Of-
ficer emergency call” does not work.

Functions & configuration EB8E4A
14 1.0/0315
“Call park” function
In order to avoid that the cell call is cancelled after it had been answered, this call can be “parked” by
pressing button 3at the control desk. Therefore, the call will be kept at the control desk (but without
an acoustical buzzer signal). By pressing X, a conversation can be built up again. When the conversa-
tion is cancelled with Xor F, the “call park” function is cleared.
Attendance function
The key switch in front of the prison cell activates the function “attendance”. The key switch has to be
connected to two inputs at the EB8E4A (“E1” to “E8”).
The system cancels an initiated officer emergency call (with “cancel on site” and “clear emergency call
only after acknowledgement”) by activating the attendance function only when already a conversation
to the respective inquiry station had been built up.
Carry out the following configuration in CCT 800 to activate the function “attendance”:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Security
>tab Key-switch.
In the drop-down list Key-switch, define the required option of the two previously selected inputs
for “attendance 1” and “attendance 2” (“Key-switch (standard)”, “Key-switch with Flag-contact”,
“Key-switch with attendance lamp”, “Key-switch with Flag and attendance”, “Key-switch (push but-
ton)”, “Key-switch (push button) with Call Park output”, “Key-switch (push button) with attendance
lamp” or “Key-switch (push button) with Flag and attendance”).
In the drop-down list Simulated input no., define the inputs (“IN1” to “IN3”) for the input message
to which the attendant contacts for the call park lamp or attendance lamp are connected.
In the drop-down list Attendance monitoring [sec], define the time in seconds after which the sys-
tem has to initiate an officer emergency call at “attendance 2”.
Select the option “none” for the input “attendance 1”, as there will be no officer emergency call
initiated automatically.
For the input “attendance 2”, select the required time in seconds after which an officer emergency
call has to be initiated automatically (“15”, “30”, “120” or “180”).
Define any unused input for the initiation of an officer emergency call after a beforehand-defined
time (without an additional call button). This input has to be configured with the function “officer
emergency call”. For further information regarding the configuration of officer emergency calls, see
”Officer emergency call” on page 13.
Note:
For activation of the “call park” function with button 3, no configuration is required.
Note:
The key switch can be switched into two different positions:
“Attendance 1”: The system gets the information that an attendant is present in the cell.
“Attendance 2”: The system gets the information that an attendant is present in the cell. Additionally, a
timer will be activated, so that an attendant must make a report to the control desk in the defined time,
otherwise the system initiates an officer emergency call automatically.
Note:
For the activation of a call park lamp and/or an attendance lamp, the required option with the respective
additional instruction (e.g. “… with Flag-contact”) has to be selected in the drop-down list Key-switch.

Sabotage
At any attempt of opening the cell terminal, a sabotage alarm will be initiated. The indication occurs as
emergency call with short buzzer interval at the control desk, in addition, the attendance lamp blinks.
The call can be acknowledged at the control desk (buzzer is switched off). However, the call can only
be deleted by activating “attendance” at the cell and if sabotage as well as the cell phone finder are
inactive – close the enclosure of the cell terminal i.e. remove the mobile device. For further information,
see ”
Attendance function” on page 14.
Carry out the following configuration in CCT 800 to activate sabotage alarms:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Security
>tab Common.
In the drop-down list Security function, choose the option “Sabotage (send level 1k5)”.
In the drop-down list Simulated input no., define the input that initiates an input message to the
control desk.
Select Subscriber > Station properties > ET808 family > EB8E4A > tab Inputs.
Activate the respective input (“IN1” to “IN3”).
Select Inputs > Input message > tab Triggering.
Right-click on the cell terminal and select “add Input message”.
In the drop-down list 15k, choose “Idle”, and in the drop-down list 1k5, choose “Active 2”.
Configure the input in CCT 800 on which the sabotage contact is connected as follows:
The sabotage contact is a NO contact: The input has to be inverted (see ”Inversion of inputs” on
page 11).
The sabotage contact is a NC contact: Do not invert the input.
Resetting a sabotage alarm
The sabotage alarm can only be reset as follows:
Acknowledge the input message at the control desk.
Switch the key switches to “Attendance 1” or “Attendance 2” on the respective cell only after the
input message had been answered.
The system now resets the sabotage alarm.
Note:
For the light switching, It is recommended to configure output “OUT4”– otherwise switching errors may
occur (see ”Offline output configuration” on page 20).
Note:
To trigger an additional output of the EB8E4A, attendant contacts can be used (see Manual
“PRO 800 Basic”).

Light
Wiring example
The cabling as shown in the diagram above allows the following functions:
Switching the light in the cell on and off (can be deactivated).
Switching the light on automatically at “attendance” (has always priority).
Light indicator (display of state e.g. via control desk or ComWIN).
Light switching in front of the cell.
Light withdrawal or light permanently switched on (via ICX messages).
Light switch in the cell
The light in the cell can be switched on and off in the prison cell directly (press button one time = “light
is switched on”, press button again = ”light is switched off”). The light control is carried out by means
of a latching relay, in order to ensure that the status of the light is not changed at a power failure. At
light withdrawal, the cell light is switched off and the light button is out of order (see ”Light withdra-

Light at attendance
If the function “Light at attendance” is activated, the system switches the light on automatically when
“attendance 1” or “attendance 2” is activated via the key switch. For further information regarding the
attendance function, see ”
Attendance function” on page 14.
For the function “Light at attendance”, define an additional input as “indicator status light” (”Light in-
dication (indication of state)):
If the light in the cell is already switched on, the light would be switched off when the latching relay
is energised at “attendance”. To avoid this, the system switches the latching relay at “attendance”
by means of the “indicator status light” only if the light is switched off.
If the “indicator status light” input is not activated after switching “attendance”, the latching relay
will be energised every ten seconds until the input is activated.
Carry out the following configuration in CCT 800 to activate the function “Light at attendance”:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Light >
tab Latching relay for light.
Activate the field Light at attendance if the light should be switched automatically on at “attend-
ance”.
Define any type for Indicator COMWIN if the light indicator is only required for “Light at attend-
ance” and no indication of the light state is needed. This is because at Indicator control desk mes-
sage, the system reserves one of the inputs (“IN1” to “IN3”) as light indicator.
Light indication (indication of state)
The status of the light can be read in via an input of the EB8E4A. It is possible to indicate the status in
the following ways (is not required when using a relay):
Indicator control desk message: The control desk indicates the input as input message.
Indicator COMWIN: Via an ICX message, the light state can be inquired. The system answers with
a message of which two digits (“TT”) can be freely defined. Optionally, it is possible to put out all
changes or to inquire the light state only once.
Carry out the following configuration in CCT 800 to activate the function Indicator control desk mes-
sage:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Light >
tab Indicator control desk message.
In the drop-down list Simulated input no., define the desired input (“IN1” to “IN3”).
Activate the desired input at Subscriber > Station properties > ET808 family > EB8E4A so that
an input message will be indicated at the control desk (level “Short”).
Carry out the following configuration in CCT 800 to activate the function Indicator COMWIN:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Light >
tab Indicator COMWIN.
In the drop-down list Type ICX, define the first two digits of parameter 2 (“00” to “FF”).

Light control in front of the cell
It is possible to install a light switch in front of the prison cell for switching on the light. For further in-
formation, see ”Wiring example” on page 16.
Light withdrawal
Via ICX messages or the control desk, it is possible to activate light withdrawal for each prison cell in-
dividually so that the light can no more be switched on in the cell. In this case, the function “light at
attendance” is still available (see ”Light at attendance” on page 17). Furthermore, the light can be
switched on permanently so that it is no longer possible to switch off the light in the cell.
The function “light permanently on” is only available with the input “indicator status light”. If the “in-
dicator status light” input is not activated after switching “attendance”, the latching relay will be ener-
gised every ten seconds until the input is activated.

EB8E4A Functions & configuration
1.0/0315 19
Offline operation
If the cell terminal loses the connection to the Intercom Server (offline), the EB8E4A will save the initi-
ated calls and sabotage alarms. In offline operation, all input and output functions are still available
(e.g. activation of the call, call park and attendance function). Even if the cell terminal itself is cut off
from its power supply, the cell calls, emergency calls and sabotage alarms that had been issued are
preserved.
Offline cell call
If the connection to the Intercom Server has been disconnected, the lamp in the front of the cell still
indicates calls. As soon as the connection between cell terminal and Intercom Server is established, the
system transmits the unacknowledged calls to the control desk immediately. After a successful call
initiation, the cell lamp turns off.
Additionally, it is possible to acknowledge a cell call in offline mode. Carry out the following configu-
ration in CCT 800 to activate the function “Acknowledging offline cell calls”:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Prison
cell call with officer emergency call > tab Prison cell call with officer emergency call.
Activate the field Quittierung offline.
Offline emergency call
If the prisoner initiates an emergency call in offline operation, the lamp in front of the cell does not light
permanently but blinks in one-second intervals (also applies for online operation). This ensures that
emergency calls will be indicated in front of the cell if the Intercom Server is not available. As soon as
a connection between the cell terminal and the Intercom Server is established, the system transmits
the unacknowledged emergency calls to the control desk. After a successful call initiation, the cell lamp
turns off.
Additionally, it is possible to acknowledge an emergency call in offline mode. Carry out the following
configuration in CCT 800 to activate the function “Acknowledging offline emergency calls”:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Prison
cell call with officer emergency call > tab Prison cell call with officer emergency call.
Activate the field Quittierung offline.
Note:
To acknowledge cell calls, emergency calls and sabotage alarms in the offline operation, it is necessary to
activate the attendance function (see ”
Attendance function” on page 14).
Note:
For the cell call in offline operation, no configuration is required.
If a cell call was initiated in offline operation, output “OUT1” will be switched.
Note:
For the emergency call in offline operation, no configuration is required.
If an emergency call was initiated in offline operation, output “OUT1” will be switched on and off in 500
ms intervals.

Offline sabotage alarm
If a sabotage alarm is initiated in offline operation, the lamp in front of the cell blinks. As soon as a con-
nection between the cell terminal and the Intercom Server is established, the system transmits the un-
acknowledged sabotage alarm to the control desk. The sabotage alarm can only be deleted after reset-
ting the message. For further information regarding resetting the message, see ”Resetting a sabotage
alarm” on page 15.
Additionally, it is possible to acknowledge a sabotage alarm in offline mode. Carry out the following
configuration in CCT 800 to activate the function “Acknowledging offline sabotage alarms”:
Select Subscriber > Station properties > ET808 family > EB8E4A > # - Station # > Security>
tab Common.
Activate the field Quittierung offline.
Offline light control
If the cell terminal goes offline, the prisoner can still turn the light on and off. As soon as a connection
between the cell terminal and the Intercom Server is established, the last switched state in the cell will
be active.
Offline output configuration
The outputs of the EB8E4A are provided for the following functions and can not be modified:
„OUT1“: Call lamp
„OUT2“: Call park lamp
„OUT3“: Attendance
„OUT4“: Cell light
Additional features
Firmware download
The firmware of the EB8E4A is downloadable in the installed state. This means that firmware updates
can be executed directly from the Intercom Server via the Intercom module to the EB8E4A. For further
information, see Manual “PRO 800 Basic”.
Note:
For the sabotage alarm in offline operation, no configuration is required.
If a sabotage alarm was detected in offline operation, output “OUT1”as well as “OUT3” will be
switched on and off in 500 ms intervals.
Note:
For the light control in offline operation, no configuration is required.
Attention:
If the configuration of the outputs differ from the offline functions, switching errors may occur. E.g. if
“OUT1” that is assigned for the call lamp in offline mode is connected to a door opener, the door opener
will be triggered by a call.
