Door phone diagram with a City Line Guard Unit.
DIAGRAM SCHEMATIC
BASIC FUNCTION
The City Line Guard Unit consists of the guard’s phone
and a panel with the same number of pushbuttons as
there are on the outdoor panel, in fact each pushbutton
on the outdoor panel has its corresponding button on the
guard’s panel (see diagram).
It has a key for its activation and disactivation.
When it is on ("day mode") the outdoor panel is left
disconnected (without power), and there is only a
connection between the telephones and the guard unit. It
is therefore impossible to call directly from the outdoor
panel to the dwellings. Only the concierge can call directly
to the dwellings from his panel with his phone.The
residents can call the concierge by picking up their phone
and pressing the door release button, which produces an
audible signal in the guard unit.The concierge can talk to
the residents by simply picking up the telephone.
When it is off ("night mode") the outdoor panel is again
connected to the telephones, working in the normal way.
From the guard unit it is impossible to make or receive
calls from the dwellings.
