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 congured for other functions; the Alert function can be used as described in relative paragraph.
