TAB: 7559
Connections
On the rear there is a terminal board for:
• Connection of the Due Fili Plus bus
• The Landing Call input. The maximum connection distance is
10 m. When suitably programmed using SaveProg, this input
can be used for the Alert function. See relative paragraph
in the installation and operation manual.

Note: Art. 7559 does not have terminals for an additional power
supply. For this reason, if the section of the Due Fili bus in which
the internal unit is located is busy with another call/conversation,
or another 7559 or 40505 is switched on for any reason, regardless
of its operating status, it will not be possible to switch on a second
7559 or 40505 and a tone will sound to warn the user. The only
possible action is to operate the lock, stair light or auxiliary function
using the dedicated buttons, provided they are not configured for
other functions; the Alert function can be used as described in the
installation and operation manual.

continues to another internal unit.
B) when a BUS cable with a characteristic
impedance of 100 Ohms (Elvox 732I or 732H
cable) enters terminals 1, 2 and the riser
stops in the internal unit
C) when a BUS cable with characteristic imped-
ance of 50 Ohms (Cat. 5 or Cat. 6 twisted pair
cable) enters terminals 1, 2 and the riser stops
in the internal unit.
