• In apartments, up to 4 apartment stations in parallel with the same user code and different internal codes
can be connected.
The internal code identifies each station of the same user. This means that intercom calls can be addressed
to the single internal code in the same apartment.
In case of intercom calls to different apartments, in case of calls coming from door units and in case of floor
call, all the user apartment stations always ring. Consider also that, after receiving a call, the internal code
0 rings immediately; the internal codes 1,  and 3 ring in sequence.
