Expert installation.<br />
General information for the installation of an <strong>ABB</strong>-<strong>Welcome</strong><br />
system in new and existing buildings. The installation of flushmounted<br />
and surface-mounted devices as well as MDRC units<br />
is described in detail in the operating manuals of the devices.<br />
Installation instructions for new buildings<br />
The following should be ensured when setting up a reliable,<br />
simple, economical and future-oriented <strong>ABB</strong>-<strong>Welcome</strong><br />
system:<br />
» The use of telecommunication cables J-Y(St)-Y in the<br />
indoor and A-2Y(L)2Y in the outdoor area with a diameter<br />
of 0.8 mm. In addition to the wire pair of the <strong>ABB</strong>-<strong>Welcome</strong><br />
2-wire bus, other pairs of wires can be kept as "reserve"<br />
in the same cable. For example, for later connection to a<br />
<strong>Busch</strong>-Watchdog movement detector in the outdoor area<br />
or as power supply for future bus devices.<br />
» For smaller systems: Looping the internal bus from device<br />
to device<br />
» For larger systems: Setup of a structure with a rising mains<br />
and several stub lines. If two rising mains are provided, the<br />
two internal bus lines can be used.<br />

An <strong>ABB</strong>-<strong>Welcome</strong> audio system should make later<br />
conversion to video easy. The conversion includes the<br />
exchange of at least one <strong>ABB</strong>-<strong>Welcome</strong> audio outdoor<br />
station with an <strong>ABB</strong>-<strong>Welcome</strong> video outdoor station and<br />
at least one <strong>ABB</strong>-<strong>Welcome</strong> audio indoor station with an<br />
<strong>ABB</strong>-<strong>Welcome</strong>Touch. The system controller need not be<br />
replaced.<br />
For branch connections in the system, video distributors<br />
must be installed for the conversion. These are not required<br />
in the internal bus – if it is looped from device to device.<br />
The setting of the terminal resistors of the system must be<br />
checked after the conversion (See 20, Chapter 02).<br />
