Installation instructions for new buildings
The following should be ensured when setting up a reliable,
simple, economical and future-oriented ABB-Welcome
system:
» The use of telecommunication cables J-Y(St)-Y in the
indoor and A-2Y(L)2Y in the outdoor area with a diameter
of 0.8 mm. In addition to the wire pair of the ABB-Welcome
2-wire bus, other pairs of wires can be kept as "reserve"
in the same cable. For example, for later connection to a
Busch-Watchdog movement detector in the outdoor area
or as power supply for future bus devices.
» For smaller systems: Looping the internal bus from device
to device
» For larger systems: Setup of a structure with a rising mains
and several stub lines. If two rising mains are provided, the
two internal bus lines can be used.
Part of daily life. The ABB-
WelcomeTouch in new buildings.
An ABB-Welcome audio system should make later
conversion to video easy. The conversion includes the
exchange of at least one ABB-Welcome audio outdoor
station with an ABB-Welcome video outdoor station and
at least one ABB-Welcome audio indoor station with an
ABB-WelcomeTouch. The system controller need not be
replaced.
For branch connections in the system, video distributors
must be installed for the conversion. These are not required
in the internal bus – if it is looped from device to device.
The setting of the terminal resistors of the system must be
checked after the conversion (See 20, Chapter 02).
