STANDARD INSTALLATION

6+N+COAXIAL SYSTEM
Standard wiring diagram for electronic video door entry
installations in buildings with a single entry point.
Operation
When one of the push-buttons of the entrance panel is
pressed, the audio unit activates the video unit (connector
19) and generates an electronic call signal (terminal 7)
which is carried by the call wire to the corresponding moni-
tor (terminal 5). The loudspeaker of the handset of the moni-
tor emits a warning sound, informing the house of the inco-
ming call. At the same time, the visitor hears a sound, pro-
duced by the loudspeaker of the audio unit, which confirms
that the call to the house has been made. The video unit swit-
ches on and captures the image of the visitor and sends the
video signal to the monitors (V1, M).
The monitor is activated and connected to the power
supply terminals (terminals -,+) when it receives the call. The
monitor then sends the supply voltage (terminals V1, M) to
the top output of the tap-off to which it is connected, allo-
wing it to receive the video signal of the video unit (termi-
nals V1, M) and to show the image of the visitor.
The monitor is also connected to the common wire (2) and
to the lock release wire (1). If the handset is picked up, the
audio wires (3 and 4) of the monitor are connected to the
entrance panel, establishing conversation with the visitor.
When the lock release button of the monitor is pressed, the
audio unit detects the closing of the lock release circuit (ter-
minal 1 to ground). The audio unit then sends an alternate
voltage (terminals 11 and 12) to the electric lock, permitting
the opening of the door.
All the signals are closed through the common wire (ter-
minal 2) of the monitor and of the audio unit.
Time settings established by the audio unit:
Time limit to answer the call 30 seconds.
