INSTALLATION OPERATION
Standard power supplier 6948 is fitted in DIGIBUS video door entry
systems to power the monitors, interphones, digital distributors, en-
trance 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: 6942 which powers the entrance panels, switch-
board, digital distributors, interphones and monitors (digital circuit), and
6947 which powers the monitors and regenerates the call signal. For
more information about the layout of power suppliers, refer to the corre-
sponding 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 to route the call. To cancel the call, simply press
button "R".
After the call button has been pressed, the entrance panel or switch-
board transmits 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 - ter-
minals of the cable riser so that any activated monitors are switched off.
Next, the entrance panel or switchboard activates the call generator in-
side 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 interphone or monitor
phonic line connects to the external entrance panel or switchboard. In
the case of video monitors and entrance panels or monitors and switch-
boards with video camera units, the monitor displays the image filmed
from the entrance panel or switchboard video camera respectively.
Once the interphone or monitor is connected, its door lock release
is enabled. The auxiliary functions may be activated irrespec-
tive of whether the internal unit is activated or not. However, the door
lock release button
lock if the internal unit is connected to the external entrance panel. Oth-
erwise 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
disconnects 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 conversation time. If the handset is replaced before the
maximum conversation time has elapsed, the interphone or monitor is
disconnected after about 5 seconds.
