Operation
When one of the push buttons on the entrance
panel is pressed the call signal generated by the
audio unit (8) is sent via the call line to the corres-
ponding telephone (6) where it is heard. At the same
time the audio unit’s own loudspeaker generates a
sound to confirm to the visitor that the call has been
made.
When the handset is picked up the electronics
associated to the telephone’s audio lines (3 and 4) is
internally connected to the entrance panel. This co-
nnection sets up the communication between the tele-
phone and the entrance panel.
When the door lock release button on the telepho-
ne is pressed, the audio unit detects the closing of the
lock release circuit (1). The audio unit then sends an
a/c voltage (11 and 12) to the electric lock, thus allo-
wing the entrance door to be opened.
The common wire (2) of the telephone and entran-
ce panel provides the return path for all the telepho-
ne signals.
