FUNCTION
1+1 wire system allows to obtain the service of a standard outdoor set
installation with conversation, call, electric lock opening, with only 2
wires in the rising column: 1 common + 1 single for each door phone.
The outdoor set is fed, with two wires only, by a 12V a.c. voltage
transformer.
To assure secrecy to all the door phones, special devices for secrecy
of conversation are inserted into the push button panel (one for each
key).
So, all the door phones will be cut off from any conversation (nothing
can be heard when picking up the handset); only the called door phone
can start a conversation with the caller, no other being able to intercept
the call.
The called house is qualifi ed to talk until another call is made from the
push button panel to other door phone.
The electric lock opening depends from the circuit of secrecy of
conversation (the lock cannot be operated unless the door phone has
been called).
