6948 - 6948/120
DESCRIPTION OF DIFFERENT INSTALLATIONS
A description follows of three DIGIBUS video door entry systems which
use power supplier 6948.
If both auxiliary functions are required, terminals F1 and F2 on the en-
trance 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 inter-
phones and monitors 8877, 6201, 6327 the corresponding connections
must be made between the interphone/monitor and digital distributor 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 en-
trance panel and secondary video/audio panels (see drawing si177).
C) Video door entry system with one video entrance panel and switch-
board equipped with monitor and video camera unit (see drawing
si176).
A) Video door entry system with one video entrance panel (drawing
SI212)
-
Key in the required user number, (i.e. 77) on the entrance panel key-
pad.
-
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 aux-
iliary functions may also be activated when the monitor has not been
called.
-
When the door lock release button is pressed
release code corresponding to the monitor user number (77) is trans-
mitted by the monitor to the cable riser. The entrance panel from
where the call originates then identifies the code and activates termi-
nal S for the set door lock activation time. Power supplier terminal S1
therefore de-energises to zero Volts for the time terminal S is acti-
vated.
-
When the video camera button is pressed
function F2 corresponding to the monitor user number (77) is trans-
mitted 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
F1 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 disconnect 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.
B) Video door entry system for building complex with main video
entrance panel and secondary video/audio panels (drawing
SI177)
-
Key in the required user number, (i.e. 77) on the main entrance panel
keypad.
-
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 sec-
ondary 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
activated monitors.
-
The call code for user number 77 is regenerated and re-routed to the
monitor 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 coun-
ter.
-
The two auxiliary functions and the door lock opening function can
all be activated when the handset is lifted or set down. The two aux-
iliary functions may also be activated when the monitor has not been
called.
-
When the door lock release button is pressed
release code corresponding to the monitor user number (77) is trans-
mitted 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 termi-
nal 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
function F2 corresponding to the monitor user number (77) is trans-
mitted 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
F1 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 trans-
mits a reset code to disconnect the monitor. The secondary panel
thus activates terminal +I to switch off the monitor and reset its "EN-
GAGED-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 secondary 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 entrance panel receiver.
C) Video door entry system with one video entrance panel and
switchboard equipped with monitor and video camera unit (draw-
ing si176)
Switchboard set to EXTERNAL mode (led in key
- Key in the required user number, (i.e. 77) on the main 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 cable riser.
