Options of flexible addressing

Assigning doorbell push-buttons to apartments

The doorbell push-buttons of an outdoor station can be freely
assigned to an apartment. When the doorbell push-button is
pressed the call is received at the fixed address. The option
of flexible addressing allows the ABB-Welcome system to
be adapted to the individual requirements of the user. This
is a big advantage – especially when a system has several
outdoor stations.
The use of several outdoor stations: uniform assignment
of call buttons
Fig. 5
With several outdoor stations within an ABB-Welcome system
the call buttons of each outdoor station are generally assigned
similarly. This means that all apartments can be called from
all outdoor stations. This is practical for buildings with several
entrances – from each of which all apartments are accessible.

Several outdoor stations with different bell fields

Alternatively, the call buttons of the various outdoor stations
can be assigned differently when all apartments are to be
called from one outdoor station and only some apartments
from additional outdoor stations.
In the example an outdoor station is mounted at the gate
entrance with which all four apartments can be called. One
outdoor station is on the left building with apartments 01 and
02 and a further outdoor station on the right building with
apartments 03 and 04. This means that only two apartments
can be called from these two outdoor stations.
The use of several outdoor stations: assigning the
standard outdoor station
The ABB-Welcome system guarantees the opening of the
door at several outdoor stations at which the visitor has rung
the bell. The resident simply presses the button "Open door"
at the indoor station. Also the associated light at the entrance
can be switched on. Opening and switching in the apartment
is also possible without an existing outside call.
For several entrances with a system with outdoor stations, one
standard outdoor station is defined for opening the door and
switching the light. The setting is made at the indoor stations of
each apartment. With the ABB-WelcomeTouch the camera image
of an outdoor station can also be activated without having
received a call. Here the camera image of the standard outdoor
station is displayed.

System controller and auxiliary power supply
The system controller supplies the other bus subscribers with
voltage and controls communication on the 2-wire bus. Start-
ing from the system controller, the 2-wire bus divides into three
bus lines, the external bus and the two internal bus lines.
The ABB-Welcome system controller additionally offers options
for connecting a door opener and hallway or path illumination.
The switching times can be set on the device.
These hints should definitely be observed to prevent faults
from occurring during the audio and video transmission.
Notes:
» All branches of the wiring system should be terminated by
a connected bus device (e.g., an indoor station, outdoor
station or a system device). This means that no branches
are to be open.
» The system controller should not be installed in the
Fig. 6
immediate vicinity of bell transformers or other switched
power supplies to prevent interference.
» Do not install the lines of the system bus together with
230 V cables.
» Connection cables for door openers should not be placed
in the same cable as the lines of the 2-wire bus.
» Avoid transitions between different cable types.
» In a cable with four or more wires, only one pair of wires
should be used for the 2-wire bus.
» When looping the 2-wire bus to a bus that is incoming or
outgoing from a device, it should not be installed in the
same cable.
» Internal and external bus must not laid in the same cable.
A system controller makes 65 consumer units available to the
ABB-Welcome. They are used to supply the connected devices.
In a one-family house, for example, this allows one video
outdoor station as well as up to four ABB-WelcomeTouch
to be operated.
In a multifamily house, for example, this allows a system with
one ABB-Welcome audio outdoor station with 15 bell buttons
and 30 audio indoor stations with handset (i.e. two per
apartment) to be operated by one system controller. For a
larger number of units an auxiliary power supply is required.*
