The device permits transforming the latter into a flush-mounting hands-free video door entry unit.
The video door entry module is none other than an audio-video interface through which it is possible to make voice
and images interact; the device is provided with inputs and outputs that enable connecting the video door entry
unit with the other appliances in the system (power supply, electrical lock, etc.).
Figure 1 - Video door entry module 01955.

Type of system.
The video door entry module 01955 can be used solely on video door entry systems of the Elvox Two Wire digital
type; it will therefore be necessary to use solely Elvox power supplies in the Elvox Two Wire range (for the speci-
fications see the relevant Elvox manuals).
To create the audio and video function the type of connection, both toward the pillar and toward the speech unit,
is made with a "2 wire non-polarized" bus cable.
The Elvox Two Wire system enables making types of systems in which the identification of the devices and controls
is digital.
Depending on the configuration of the system, each of the connected devices is characterized by a numerical
code between 1 and 200 (the value must be univocal) and is able to receive and send data packets containing all
the information related to the management of the communication; each data packet is composed of the identifi-
cation of the destination device and the command that the latter must actuate.
All the control operations typical of a video door entry system such as, for instance, call, electrical lock opening,
stair lighting, etc., are therefore coded.
The voice unit for the voice communication and the video signal for viewing the images instead are still analogue
signals.
Lastly as regards the type of cables to use for the connection between the components of the system, both toward
the pillar and toward the speech unit, it is recommended to use the twisted bipolar BUS cable with a cross-section
of 1 mm2 (type art. 732H/100 Elvox or the equivalent).
Advantages of the Elvox Two Wire system.
The most important advantage offered by the Elvox Two Wire system, compared to other video door entry systems
(classic “8 wire + n” analogue or digital with multi-wire DigiBus), is its use in wiring the whole system with just 2
conductors, twisted and not polarized, on which the data, audio signal, video signal and necessary power supply
are conveyed to the connected devices.
Thanks to this characteristic, the system is therefore ideal to be used both in small-medium residential systems
and in large building complexes (up to a maximum of 200 indoor stations) because it considerably simplifies the
wiring operations.
Another advantage of using the Elvox Two-Wire system is its extreme flexibility in the case of subsequent system
expansion; it is possible, in fact, to add new indoor stations simply with the aid of the pillar without having to wire
further cables toward the power supply.
The digital management of all the commands (call bell duration, type of bell, call time duration, answer time dura-
tion, entry with password or programmed key, etc.) lastly enables programming all the parameters of the devices
according to the different requirements of each user.

Power input.
The consumption of the video door entry 01955 depends on the current operating mode of the video door entry
unit (standby, on call, red/green LED on, control activation, etc.).
The mean values of the power input in the three typical modes of operation are the following:
- on standby 6 mA.
- on call 250 mA.
- with monitor on 200 mA.
N.B. The above values are approximate.
Operation of the Elvox Two Wire system.
The Elvox Two Wire system enables digital coding of the devices and the commands that are sent or that come
from the external panel; the latter can be considered as the MASTER device (main appliance that manages the
communication between the digital devices in the system) while every other single digital device (including the se-
condary panels) can be considered as a SLAVE (secondary appliance that is piloted/controlled by the master).
The entry panel is therefore essential for the operation of the Elvox Two Wire system and must always be installed in
the system; all the programming parameters (call time, type of bell, electrical lock opening, code numbers of the in-
door stations, etc.) are set and saved (until the next programming) in the main external panel (EEPROM memory).
For programming the panel and all the parameters correlated with it, see the related Elvox technical documenta-
tion.
Per la programmazione della targa e di tutti i parametri ad essa correlati si veda la relativa documentazione tecnica
Elvox.
Power Supplies and other Elvox.
The power supplies and other accessories that can be used for installing the system are all those of the Elvox Two
Wire range; in particular, the following articles are recommended:
• 6922 (standard video door entry system power supply)
• 6923 (additional power supply for panels and monitor in parallel)
• 6582 (power supply for additional video cameras and landing video)
• 692S ( separator for the division of conversation areas, intercommunicating networks and landing door panels

General information on the digital controls.
The digital controls are packets of data that can be sent from/to each digital device and contain the information/
instructions that enable activating a particular function (video call, intercom call, lock opening, stair lighting, auxiliary
function activation, etc.) . The control is mainly composed of 3 significant fields: < receiver - command code - sen-
der >. An example of hexadecimal coding of a command is the following:
< 01 - 0E - FE > = LOCK
that represents the lock opening command of the main panel sent by device no. 1. Typically, in the Elvox Two Wire
system, the main video door entry commands are the following:
- LOCK command
- FUNCTION F1 command
- FUNCTION F2 command
- AUX 1 SERVICE command
- AUX 2 SERVICE command
These commands pilot actuators that are in the panels or in special auxiliary digital relays to be set up; in the case
of the above-listed main commands (and in reference to the Elvox Two Wire panel series 89FX/XX) the actuators
are the following:
actuator S+/S- S+(positive output 12Vdc max 200mA) with S- that closes to ground on receiving
the LOCK command.
actuator F1 Contact that closes to ground on receiving the F1 FUNCTION command.
12Vdc power supply that can be taken from the '+12V' terminal max 100mA.
To be used to control an auxiliary external relay.
actuator F2 Contact that closes to ground on receiving the F2 FUNCTION command.
12Vdc power supply that can be taken from the '+12V' terminal max 100mA.
To be used to control an auxiliary external relay.
AUX 1 SERVICE actuator Contact on digital auxiliary relay (to set up) Elvox art. 69RH (see Elvox technical
documentation art. 69RH)
AUX 2 SERVICE actuator Contact on digital auxiliary relay (to set up) Elvox art. 69RH (see Elvox technical
documentation art. 69RH)
NOTE: There are up to a maximum of 16 AUX SERVICES in the system.
Each single command is sent by pressing a button (associated with the same command) on the device. Other
commands can be associated and programmed as preferred on the available buttons via programmable time
switch 950C or pc, serial interface 692I (or usb 692I/U) and Elvox “SAVEPROG” software.

WARNING!
The setting for selector S is made in the phase of installation.
WARNING: The setting for button "C" as 2ndF can also be made via the advanced programming of the video door
entry unit using the programmable time switch 950C or a PC with serial interface 692I (or usb 692I/U)and Elvox
“SAVEPROG” software. In this case it is possible (via software) to configure button "C" as 2ndF regardless of the
position of the selector S; if this forcing is removed the functionality of the button is once again identified by the
position of S (for further details see under the heading "CONFIGURATION OF THE OPTIONAL FUNCTIONS OF
THE VIDEO DOOR ENTRY UNIT").
The “Second Function” button (2ndF).
With the default configuration set in the factory, the front buttons enable sending the AUX 1 SERVICE, LOCK and
SELF-START buttons by pressing respectively the push-buttons "A", "B" and "C" on the monitor.
The system moreover enables sending further additional “auxiliary functions” commands that can be used, for
instance, to control cyclical viewing of a number of internal video cameras, opening the landing lock or other
auxiliary devices such as switching on the secondary stairs lighting, etc.; to be able to use these controls it is
necessary to configure the "C" button on the monitor as the “second function” (2ndf) button.

The 2ndF button, pressed in combination with other buttons, sends further separate additional commands
on the digital line.
When button "C" is configured as 2ndF the correspondence between command - button is the following:
LOCK Pressing button "B"
AUX 1 SERVICE Pressing button "A"
AUX 2 SERVICE Pressing buttons "C+B"
SELF-START Pressing buttons "C+A"

FREE Pressing buttons "C+F" (by default no function)
FREE Pressing buttons "C+H" (by default FUNCTION F1)
FREE Pressing buttons "C+I" (by default FUNCTION F2)
N.B.: When you want to insert the video door entry unit in an intercommunicating network, it is necessary to set
button "C" as the second function (2ndF) to be able to access the buttons for sending intercom calls (that must
be appropriately programmed). In this configuration 4 buttons are available for direct intercom calls, which can
be made by keeping button "C" pressed:
C+E INTERCOM call 1
C+F INTERCOM call 2
C+H INTERCOM call 3
C+I INTERCOM call 4
IMPORTANT: The command-button-function combinations are also given in the section “QUICK GUIDE TO USING
THE VIDEO DOOR ENTRY UNIT.”
All the buttons and the combination in 2ndF are programmable as preferred for sending particular function com-
mands, except for the hands-free button (button “D”).

Warnings for device coding and programming
The identification phase (coding via numerical identification - ID) for some devices of the Elvox Two Wire system
is done during the programming phase while for others it is done with jumpers or dip-switches in the device and
that must be set during the phase of installation (see the instruction sheets of the single devices).
Important: It is vital, during the programming phase, for the system to have an electronic entrance panel model
89FX/XX, identified as the “Master entrance panel.”
In an Elvox Two Wire system there must be only one Master entrance panel (identification code ID = 1). The various
devices in the system must be programmed after their identification; this programming can be carried out with
electronic entrance panels model 89FX/XX or programmer 950C or with a PC by means of the serial interface 692I
(or usb 692I/U and the Elvox “SAVEPROG” software.
Using the electronic entrance panels with conventional buttons (not with an alphanumeric keyboard) allows only
standard programming of the devices but not advanced programming; this programming is anyhow enough for
the operation of the devices in most systems.

Figure 9 - Releasing button
Numerical coding of the video door entry unit.
Device programming phases.
For the correct configuration and programming of the system, follow this procedure in sequence:
- Install and connect all the system devices
- For video door entry systems, set the jumper for video termination as shown on the connection diagrams
- If present in the system code the Elvox devices 692S, 69RH, 692U, 692U/C, 69AV, 69AM, 69AU
- When there are electronic entrance panels with pushbuttons, do the hardware programming of any pushbutton
modules
- In systems with multiple electronic entrance panels, set the SLAVE panels (generally using the specific jumper)
and code without connecting the MASTER entrance panel (ID code of the SLAVE panels between 2 and 15)
- Connect and power up the MASTER entrance panel (it is the panel with ID = 1)
- Program any entrance panel parameters. The essential parameters to program are shown on the connection
diagrams.
- Code the audio and video door entry units from the MASTER entrance panel.
- Do any advanced programming of the audio and video door entry units (intercom push-buttons, group calls,
digital relay activation ….).
The video door entry unit of the Elvox Two Wire system is identified in the system with a numerical code in the interval
from 1 to 200; it is therefore necessary to program this code with the following procedure:
• Unhook the cover of the button "C" (hands-free function);

14
• Briefly, using a screwdriver or a small tool, press the push button R below the button "C" (figure 10);
• Press and hold down the button "B" for at least 3 seconds (door opening function) (figure 11);
• The red LED of the video door entry unit lights up confirming that the device is ready to be encoded.
• Send a call to the video door entry unit from the MASTER panel with the desired numerical code; if you have
a panel with an alphanumeric keyboard it is enough to key in this code and send it to the device by pressing the
confirmation button on the panel while, if you have a push-buttons panel, send the call with the button that you
want to associate with the video door entry unit on the panel.
• The programming of the video door entry unit with the desired code is confirmed by the red LED on the monitor
turning off and an audible warning as confirmation on the panel.
• Lastly, check that the video door entry unit answers the call (with an alphanumeric panel, key in the set code
and press the confirmation button on the panel while, if you have a push-buttons panel, press the button corre-
sponding to the call).
If you do not have a panel with alphanumerical buttons or single buttons it is necessary to use the programmable
time switch or 950C or the serial interface 692I (or usb 692I/U) with PC and Elvox “SAVEPROG” software.

Functions of the video door entry unit
Secondary numerical coding of the video door entry unit
Programming the secondary identification code is only required when you want to have more than one video door
entry unit ring at the same time with the same push-button or call code.
The video door entry units that must ring at the same time are associated with the same group; The “master” video
door entry unit is programmed first by means of the numerical coding procedure described above (see under the
heading NUMERICAL CODING OF THE VIDEO DOOR ENTRY UNIT), while the additional group video door entry
units are programmed with the secondary identification code.
A maximum of four video door entry units can be associated with the same group, without the need for program-
mer type 950C or the serial interface 692I (or usb 6291I/U) with PC and Elvox "SAVEPROGR” software.
In the case of video door entry units it is necessary to add an additional power supply art. 6923 for each additional
monitor after the second one (that is starting from the third one).
By using the programmable time switch 950C or the serial interface 692I with PC and Elvox “SAVEPROG” sof-
tware, it is possible to program the activation of the bell of all the video door entry units without all the monitors
coming on at the same time; then only the monitor of the video door entry unit being answered from is activated,
with the self-start push button, in such a way as not to have to use any additional power supplies.
If you want to program the video door entry unit as a secondary one of a certain master, the procedure is the
following:
• Unhook the cover of the button "C"
• Press the push button “R” located under the button "C" and then hold down the Lock ("B") and Self-Start ("C")
buttons for at least 3 seconds until there is an audible warning from the video door entry unit and when the monitor
comes on if there is a video panel
• From the panel, press the corresponding push button or enter the number of the master; automatically the
secondary one will acquire the ID referring to the master (for more details see the Elvox technical documentation).
Alternatively you can proceed by setting the secondary identification using the programmable time switch 950C
or the serial interface 692I (or usb 629I/U) with PC and Elvox “SAVEPROG” software.
This type of approach enables associating the same group with up to 8 devices (video/audio door entry units).
Answering calls
When a call is made from a speech unit (external panel or consumer unit), the deated to the called numerical
identification modulates the programmed call tone on the speaker inserted in the monitor; the video door entry
unit then emits an audible warning and, if there is also the video signal (that is, for instance, there is an audio/video
panel), the LCD monitor will switch on to show the person making the call.
As it is a hands-free system, to answer the call and communicate with the speech unit it is necessary to press
and hold down the answer button "D" (fig. 6) for the entire duration of the conversation; it is moreover possible
to set the “Hands Free” answer mode (also called speakerphone On/Off) that allows enabling the speakerphone
on first pressing the button "D" and disabling it when pressing it next (see chapter “CONFIGURATION OF THE
VIDEO DOOR ENTRY UNIT”).
The call activation time is set as a panel parameter; these parameters can all be set in the phase of programming
the external panel (MASTER) and they involve various functions such as timing, recording consumers, etc. (for
the complete list of the parameters see the Elvox technical documentation related to the panel used and also the
chapter “PROGRAMMING THE Elvox Two Wire PANEL”).
If the video door entry unit is interfaced with the By-me home automation system, it is possible to end the call
voluntarily; for more details, see the chapter “INTEGRATION OF THE By-me SYSTEM”.

16
Functions of the video door entry unit
Self-start function
This function enables activating audio and video communication on the speech unit without a call being received;
this can be useful, for instance, in the case in which it is wished to check the external zone or an internal zone
where an additional video camera has been installed.
To activate self-starting on the external panel it is necessary to send the SELF-START command associated with
the button "C" when the 2ndF is not set (or "C"+"A" if the 2ndF is enabled - see the chapter "THE SECOND
FUNCTION BUTTON (2ndF)").
Repeatedly pressing the button "C" (therefore repeatedly sending the SELF-START command) cyclically performs
self-start on any other secondary panels fitted; the progressive sequence is programmable as a panel parameter
(using the programmable time switch 950C or PC serial interface 692I (or usb 692I/U) and the Elvox “SAVEPROG”
software.
The self-start on further additional stand-alone video cameras type CCTV (for instance 20560, 14560, 20565,
14565) is constrained by the presence of the Elvox video interface 69AV/M (or audio/video 69AM).
For greater details see the chapter “AUDIO/VIDEO INTERFACE FOR VIDEO CAMERAS” in this manual.
Conversation Privacy
The “Conversation Privacy” function enables communicating with the speech unit only if a call has arrived or if a
self-start has been performed; it is not possible to listen to any other communications in progress nor run a self-
start while there a conversation is in progress.
In Elvox Two Wire systems the "confidential conversation" function is always enabled.

17
Functions of the video door entry unit
“Door Open” indicator.
This function enables displaying a “Door Open” signal on the video door entry unit by lighting up the green LED on
the right-hand side of the LCD monitor; this application is useful to avoid unwanted access to the housing unit.
To enable this function it is necessary, when the door is closed to connect a sensor with a N.O. contact to the
terminals ‘PA' and 'M' of the panel of the Elvox Two Wire system.
The green led lights up when at least one of the enabled doors closes the contact on the respective panel.

LOCK command activation.
This command opens the lock of the door or the gate that provides access to the housing unit.
The command is made by pressing the button "B" that sends the LOCK command to the panel which activates
the corresponding actuator.
With reference to the Elvox Two Wire panel series 89FX/XX its terminals to be used are the following:
• “S+/S-“ for locks at 12 V dc with low absorption (200 mA max continuous)
• “+12V/SR” for locks with high absorption (specific external relay 12 V dc and dedicated power supply)
The activation time can be programmed as a panel parameter (see the chapter “PROGRAMMING THE Elvox”
TWO WIRE PANEL); the LOCK command is activated with both the MONITOR ON and OFF.
