drawings.
istribution:
We will situate one or more
D4L-R5 video distributors on each floor
(one for each 4 monitors). We will cut all the
independent call lines coming from the door
panel (currently connected to ground) and
we will connect them to the distributor's
ground. The number of independent call
lines remaining on that floor will be equal to
the number of apartments, the rest will
continue to the following floor. We must
connect the ones that remain to the ground
of each of the 4 distributed outputs
(SPL.OUT) of the D4L-R5, the rest will be
joined and connected to the distributor
output. We will do the same with the 4
common terminals, as shown in

istribution:
We will situate one or more
D4L-R5R video distributors on each floor
(one for each 4 monitors) and a junction
box for connection wires '+', '-', 'A/D' and its
later branch to
We
will cut all the independent call lines
coming from the door panel (currently
connected to ground) and we will connect
them to the ground assigned terminal of the
junction box. The number of independent
call lines remaining on that floor will be
equal to the number of apartments, the rest
will continue to the following floor. We must
connect the ones that remain to the ground
of junction box, the rest will be joined and
connected to ground of the junction box to
the following floor. We will do the same with
the wires '+' and 'A/D' (assign terminal for
'+' and other terminal for 'A/D' in the
junction box), the video wires will be
connected to the D4L-R5R distributors, as
shown in

IMPORTANT:
partments:
We will disconnect the telephone and connect the monitor following the
corresponding instructions indicated for the door panel. If a parallel monitor is needed then an
additional power supply must be installed on that floor (see page 125), however if the parallel unit
to be installed is a telephone or call repeater, then additional power is unnecessary. Only one
additional unit per apartment can be installed. The maximum number of terminals in total is 200
(including parallel units).
We must be sure that in the apartments there are no relays, call repeaters or
parallel telephones left over from the previous installation, otherwise serious damage
could be caused to the new system or even to the apartment (they could burn).
