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 the relative paragraph.
Note: Art. 40505 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 40505 is
switched on for any reason, regardless of its operating status, it will not be possible to switch on a second
40505 and a tone will sound to warn the user. The only possible action is to operate the lock using the dedi-
cated button, provided it is not congured for other functions; the Alert function can be used as described in
the relative paragraph.
