INSTALLATION OPERATION
Standard power supplier Art. 6948 is fitted in DIGIBUS video door entry systems
to power the monitors, interphones, digital distributors, entrance panels and
switchboard. In some installations however, due to particularly long cable runs
prone to excessive voltage drops or the number of internal units installed, the
following additional power supply units may be installed: Art. 6942 which powers
the entrance panels, switchboard, digital distributors, interphones and monitors
(digital circuit), and Art. 6947 which powers the monitors and regenerates the call
signal. For more information about the layout of power suppliers, refer to the
corresponding installation wiring diagrams. To call internal units (interphones or
monitors) from the entrance panel or switchboard, simply key in the user number
on the entrance panel or switchboard keypad and press button "C" or
route the call. To cancel the call, simply press button "R".
After the call button has been pressed, the entrance panel or switchboard trans-
mits a digital code which connects the internal unit. The first entrance panel or
switchboard connected to the monitor (or interphone) cable riser then briefly
disconnects the power supply to the + and - terminals of the cable riser so that
any activated monitors are switched off. Next, the entrance panel or switchboard
activates the call generator inside the power supplier for the set call time and
routes the call signal to the cable riser. At the end of the call signal, the inter-
phone or monitor phonic line connects to the external entrance panel or switch-
board. In the case of video monitors and entrance panels or monitors and
switchboards with video camera units, the monitor displays the image filmed from
the entrance panel or switchboard video camera respectively. Once the inter-
phone or monitor is connected, its door lock release
auxiliary functions may be activated irrespective of whether the internal unit is
activated or not. However, the door lock release button
the entrance panel door lock if the internal unit is connected to the external en-
trance panel. Otherwise it will call the porter's switchboard. Once the call has
been routed to the internal unit, the two units will only remain connected for the
reply delay time set for the entrance panel or switchboard. If the delay time
elapses before the handset is lifted, the entrance panel or switchboard discon-
nects the internal unit. If instead the handset is lifted within the set reply time, the
call is connected and the two units can communicate for the maximum conver-
sation time. If the handset is replaced before the maximum conversation time has
elapsed, the interphone or monitor is disconnected after about 5 seconds.
DESCRIPTION OF DIFFERENT INSTALLATIONS
A description follows of three DIGIBUS video door entry systems which use
power supplier Art. 6948.
If both auxiliary functions are required, terminals F1 and F2 on the entrance
panel (or switchboard) must be connected to the corresponding terminals on
the power supplier.
If both the auxiliary functions are required in installations fitted with interphones
and monitors Art. 8877, 6201, 6327 the corresponding connections must be
made between the interphone/monitor and digital distributor Art. 949B
A) Video door entry system with one video entrance panel (see drawing SI212).
B) Video door entry system for building complex with main video entrance
panel and secondary video/audio panels (see drawing si177).
C) Video door entry system with one video entrance panel and switchboard
equipped with monitor and video camera unit (see drawing si176).

- Key in the required user number, (i.e. 77) on the entrance panel keypad.
- Confirm with button "C".
- Terminal +L on the entrance panel activates.
- The digital code corresponding to user number 77 is routed along line 1 to
the monitor cable riser.
- Terminal +I briefly activates to switch off any activated monitors.
- The phonic circuit for monitor number 77 connects to the cable riser.
- Entrance panel terminal CH activates for the set call time and routes the call
signal along line 3 of the cable riser.
- The entrance panel phonic circuit connects at the end of the call time.
- If the monitor handset is not lifted the entrance panel activates the reply time
counter.
- If instead the monitor handset is lifted within the set reply time, the entrance
panel activates the maximum conversation time counter.
- The two auxiliary functions and the door lock opening function may all be
activated when the handset is lifted or set down. The two auxiliary functions
may also be activated when the monitor has not been called.
- When the door lock release button is pressed
lease code corresponding to the monitor user number (77) is transmitted by
the monitor to the cable riser. The entrance panel from where the call orig-
inates then identifies the code and activates terminal S for the set door lock
activation time. Power supplier terminal S1 therefore de-energises to zero
Volts for the time terminal S is activated.
- When the video camera button is pressed
tion F2 corresponding to the monitor user number (77) is transmitted by the
monitor to the cable riser. The entrance panel then identifies the code and

activates terminal F2 for the activation time set for auxiliary function F2.
- When the light button is pressed
corresponding to the monitor user number (77) is transmitted by the monitor
to the cable riser. The entrance panel then identifies the code and activates
terminal F1 for the activation time set for auxiliary function EM1.
- Once the reply delay time or maximum conversation time has elapsed, the
entrance panel connected to the monitor transmits a reset code to discon-
nect the monitor. Terminal +1 is thus activated to switch off the monitor.
- The same sequence occurs if the monitor handset is replaced before the
maximum conversation time has elapsed. Five seconds after the handset is
replaced, the entrance panel transmits a reset code and activates terminal
+I.

trance panel and secondary video/audio panels (drawing SI177)
Key in the required user number, (i.e. 77) on the main entrance panel key-
pad.
Confirm with button "C".
Terminal +L on the main entrance panel activates.
The digital code corresponding to user number 77 is routed along line 1 to
the cable riser.
The digital call code for user number 77 is recognised by all the secondary
entrance panels. If the call number (77) keyed in falls between the first
and final call number set for one of the secondary panels, the following
sequence occurs:
The secondary panel in question switches to "ENGAGED-WAIT" mode.
Terminal +I on the secondary panel briefly activates to switch off any acti-
vated monitors.
The call code for user number 77 is regenerated and re-routed to the mon-
itor cable riser.
The phonic circuit for monitor number 77 connects to the cable riser.
Terminal CH on the secondary panel activates for the call time set for the
secondary panel and routes the call signal along line 3 of the cable riser.
The main entrance panel phonic circuit connects at the end of the call time
set for the main entrance panel.
If the monitor handset is not lifted the main entrance panel activates the
reply time counter.
If instead the monitor handset is lifted within the set reply time, the main
entrance panel activates the maximum conversation time counter.
The two auxiliary functions and the door lock opening function can all be
activated when the handset is lifted or set down. The two auxiliary functions
may also be activated when the monitor has not been called.
When the door lock release button is pressed
lease code corresponding to the monitor user number (77) is transmitted by
the monitor to the entrance panel. The main entrance panel from where the
call originates then identifies the code and activates terminal S for the set
door lock activation time. Power supplier terminal S1 therefore de-energises
to zero Volts for the time terminal S is activated.
If the "door lock enable" parameter for the secondary panel which repeated
the call is set to 0001, the secondary panel will also activate its own terminal
S when the door lock release button is pressed
When the video camera button is pressed
tion F2 corresponding to the monitor user number (77) is transmitted by the
monitor to the cable riser. The secondary and main entrance panels then
identify the code and activate their respective terminals F2 for the activation
time set for auxiliary function F2.
When the light button is pressed
corresponding to the monitor user number (77) is transmitted by the monitor
to the cable riser. The secondary and main entrance panels then identify the
code and activate their respective terminals F1 for the activation time set for
auxiliary function F1.
Once the reply delay time or maximum conversation time has elapsed, the
main entrance panel connected to the monitor transmits a reset code to
disconnect the monitor. The secondary panel thus activates terminal +I to
switch off the monitor and reset its "ENGAGED-WAIT" status.
The same sequence occurs if the monitor handset is replaced before the
maximum conversation time has elapsed. Five seconds after the handset is
replaced, the main entrance panel transmits a reset code and the second-
ary entrance panel activates terminal +I.
When the main entrance panel is connected to a monitor, calls to internal
units can still be made from the secondary panels which are not ENGAGED.
N.B.: in building complex installations, the main entrance panel call signal
activation time must be at least a second longer than the time set for the
stairway panels to prevent the call signal from returning to the main en-
trance panel receiver.
