1.2 Terminology
Telephone line Analogue (2 conductors) connecting to a public telephone
network (public line) or to a local telephone system (local
line).
Line connection The start of a telephone connection (the same as picking up a
phone handset).
Line disconnection End of connection (the same as replacing a phone handset).
Option DTMF - a tone option combination of two tones (chooses also
special signs * and #, uses breaking the loop Flash)
Impulsive –option by breaking the loop (chooses only digits)
Incoming call Connection between a A-VarioBell and a phone made by
selecting an option on the phone. The A-VarioBell connects
the call after set number of rings. The A-VarioBell can be
programmed from the phone following a connection by
inputting a password.
Outbound call Connection between the A-VarioBell and a phone made by
choosing an option on the A-VarioBell (i.e. Pressing a button).
Call connection Signalised when following the dialled number is picked up.
This signal is not available on an analogue line, but the ringing
tone ends and a connection begins. It is difficult to identify the
exact moment this occurs.
Code lock Function for relay connections by inputting a combination of up
to 10 buttons or keyboard keys (after pressing the key symbol)
Code relay between Doorphone A-VarioBell and the electric lock can be
connected code relay (COSW - CodeSwitch), which is located
at the lock and lock activates only when is the same the
specified serial combination of the A-VarioBell and set the code
on the board relay (COSW).
External code Combination of 10 buttons or keyboard keys (after pressing the
key symbol) for a relay connection. External = being input on
the A-VarioBell outside the building
Internal code Digits combination dial from phone for relay activation (DTMF).
Internal = dial by phone –inside building ( phone connected to
other PBX extension
RTC real time clock with backup ACU
The manufacturer continuously improves the product firmware. The
technology used allows you to upload to A-VarioBell the latest version of
the firmware any time using a standard computer with A-VarioBellSet and
USB cable. The latest version of the firmware is available at

1.3 Version A-VarioBell door phone and differences
A-VarioBell door phone system is conceived as system that provides
a final solution based on a modular design. The adjustable features and
parameters are for maximal version and each version are sorted by usage of
those features.Therefore is necessary to set up the parameters for all versions
including any add-on parameters for each mechanical solution.
A-VarioBell door phone uses all parameters in default. The analog
camera is not included only.
1.4 Door phone sets
Basic module VBD-xx –A-VarioBell basic module has 2 buttons (VBD-
02), one button (VBD-01) or no button (VBD-00).
Extending modules VBDx-mod –exist just 2 types:
- VBD5-mod is module with 5 buttons
- VBD10-mod is module with 10 buttons
Advantage is that button numbering is not depending on modules
connection but is adjustable by DIP switch which is on each module (via.
follow).
Last extending module is keypad VBDKey –i tis not neccessary set up
keypad position and not depends on keypad installation. (via follow).

1. Microphone (placed in plastic cover, output at board bottom
2. PC connection connector –USB cable
3. BUS connector for connection extending modules and keypad
4. ACU battery RTC (real time clock chip)
5. Speaker –output at board bottom. At top of board is connector for
connection of external speaker
6. 12V AC/DC power supply for:
- relays control
- board heating
- name cards lighting
- external powering of door phone (DIP 3 and 4)
-exit button circuit
- LED signalling on front panel
7. relays –are galvanically isolated switchable contacts, max. 48V, max.
1,5A
At relay 1 is available function of code relay (COSW –CodeSwitch) (via.
page.29)
8. Exit button –works in circuit of current loop. The length of connected
wires to button might be up 500m. Functionality condition is presents of
12V power on screw (6)
9. Analog phone line (not depends on polarity)
10. Grounding –connection for grounding against static electricity –protect
door phone electronic as same as PBX
11. DIP switch:
1 = Servis –used when password is forgotten.
Incoming call is going directly to
programming mode where you can setup
new password. (do not forget return back
to off)
2 = heating –activate integrated board heating
3 = external power supply
4 = External power supply –switching allways 3 and 4 simultaneously. Powering
is used from screw 12V (6) and there are 2 reasons for usage:
- using relay in mode 7 or 8 - permanent relay close/open is possible with
external powering only. Do not forget setup rameter 64
- connection of door phone to PBX extension which has troubles with
current consumption after PBX start (Siemens).
5 = name cards lighting (switch ON/OFF LED lighting for name cards)

14 A-VarioBell –User and service manual
1.5.1 Power supply - screw (6)
Power supply 12V might be DC or AC, not depends on polarity, from 12V
is max. consumption 250mA.
Power supply is possible use for electrical lock powering . then is
recommended power supply 12V/1A
It is possible use power supply 24V DC. It is mainly suitable during
installation where power supply already exists and it is used for example
for access system control. Board heating has regulating element for power
restriction. The other circuits comply to voltage 24V. You must not use AC
power supply! Just DC. During connection not depends on polarity.
Power supply on screw (6) is neccessary for following features:
- relay control (powering of relay induction)
- board heating (DIP 2 is activated, current regulation according
voltage and temperature)
- name cards lighting ( DIP 5 is activated)
- external powering of door phone (DIP 3 and 4). during
permanent power supply is possible use relays mode 7 and 8.
(caution for rameter 64).
- powering of exit button circuit
- powering of LED signalling on front panel
1.5.2 Exit button –screw (8)
Exit button is designed for direct relays control. At each relay you can
setup switching for 1 or 2 pulses. The button (screw (8)) is connected in
circuit of current loop powering from 12V (screw (6)). By this way you can
connect exit button for cable up to 500m.
1.5.3 BUS for buttons extending
This BUS allows
connection of extending buttons up
to 87 buttons including keypad.
The BUS includes except seriál
data also power for name cards
lighting.
Button module is supply in
2 versions:
VBD10-mod –designed
for 10 buttons –5 in left and 5 in

1.6 Connection of extending modules VBD10(5)-mod
Buttons extending modules are VBD10-mod with 10 buttons and
VBD5-mod with 5 buttons. Very important is numbering plan , connection is
various,it means that modules you can connect as you desire independently
from numbering!
Buttons numbering will be explained later , however it is setup by DIP
switch at each button module (6).
VBDx-mod electronic board is connect to A-VarioBell mechanical button
panel through screw terminal (5) and 3 wire cable (4). The connector (7) is not
used at version analog A-VarioBell .
Connection to basic module is provide by flat cables K1. (1) is
connection to basic module, (2) is connection of following button module, (3) is
connection between button modules (still the same flat cable K1)

1.6.2 Example of modules connection VBD5-mod
Mutual connection is provide by flat cable K1. In example is used basic
module with 1 button (rameter 6# = 1 via page Chyba! Záložka není
definována.) and in connection is also used keypad module VBDKey. Modules
numbering is setup by DIP switches (6) showing allways next to appropriate
module. Buttons number response to description in left column next to
modules. Keypad module is identify automatically and there is no neccessity of
any setting. Connection place is various. When cables K1 will be connected

1.6.3 Buttons numbering
Buttons numbering depends on 2 settings:
1. Constant in basic module (buttons number on basic module) –rameter
6# - via page Chyba! Záložka není definována..
2. DIP switch setting on each button module
Numbering not depends on way (order) connection of each button
modules.
Constant 6# = [0-1-2] setup in every basic module determine how many
buttons has front mechanical panel of basic module. It has influence to button
numbering in numbering moving. That is adding this constant to setup button
number.
As you can see on picture DIP switch setting of button module is the same
but first button of button module VBD5mod is changed from 1 to 3 according
setting of constant 6#.
DIP switch setting (6) on button module.
Every DIP position has following functionality:
DIP 1 –4 = number setting of previous buttons on
button modules (basic module is not calculated!!)
DIP 5 = setting of own module, if mechanical front
panel has 5 or 10 buttons

20 A-VarioBell –User and service manual
Modules numbering is on the picture. In left part are modules with 5 buttons
VBD5-mod and in right part are modules with 10 buttons VBD10-mod.
Module with desired numbering you find on this picture and on the left is
DIP switch combination (6) which you have to setup on this module.
Numbering not depends on mutual modules connection by K1 cables
When you connect to system 2 button modules with the same DIP switch
setting nothing will happen. However both those modules will have same
buttons number and due this same functionality.
Keypad module does not need any setting
When you connect 2 keypads into system then both will work the same
way.
