free@home Touch 7" (Fig. 38)
The free@home Touch 7" serves as indoor video station
for the ABB-Welcome door communication system and for
the central control of free@home functions, such as mov-
ing blinds, switching scenes, or controlling room tempera-
ture controllers (as extension unit).
The panel is connected to both bus systems, the
free@home bus and the Welcome bus. The audio/video
signals are transmitted and the device is supplied with
power exclusively via the Welcome bus. The panel can
therefore also be used as a pure video indoor station
without a connection to the free@home system.
It is not possible to operate the panel without being con-
nected to the Welcome bus. This means that at least one
ABB-Welcome system controller or one additional power
supply is to be provided to ensure that the panel is sup-
plied with power.
Up to 16 free@home functions can be positioned on the
free@home operating page. The room temperature con-
troller function occupies two function positions. Program-
ming is carried out via the user interface of the System
Access Point.
In addition, the panel acts as gateway which mutually
compiles the telegrams of the two bus systems. This, for
example, makes it possible to switch an actuator in the
free@home system during an incoming door call of the
ABB-Welcome system, or to use a sensor in the
free@home system to send an "Open door" command to
the ABB-Welcome system.
Each of these functions appears as separate entry in the
"Allocation" area. The functions can be positioned on the
floor plan and then, like any other sensor or actuator,
connected in the "Linking" area with other sensors and
actuators.
The "Door call" function offers 4 linking functions for each
of the 4 possible Welcome outdoor stations. This allows
specific actions to be configured separately for each en-
trance of the house. These are triggered as soon as the
visitor rings the bell at one of the outdoor stations.
The "Door opener" function offers 5 connecting functions:
Either one of the 4 possible door openers of the Welcome
system can be specifically activated (to a open a specific
door with the one sensor), or a door opener can be de-
fined which dynamically opens the door from which a door
call is currently being made (all doors can be opened with
only one sensor, wherever the bell is being rung from).
