Check that the connections of the system are
carried out correctly.
Put the system in use by connecting the
power supply to the mains.
By pushing a call button from the external
push-button panel, it activates the bell of the
corresponding monitor and it activates the
system for a time of about 100 seconds. The
images appear on the monitor a few seconds
after the call.
If in the meantime another call occurs, the
monitor shuts itself off and connects the last
call. The system switches off automatically
after 100 sec.
In case more calls occur simultaneously, a
protection circuit against overloading and
short circuiting is provided to disable the
Working instructions
timer and therefore to shut off the system.
In the absence of calls from the door station,
from any monitor (if provided in the system) it
is possible to control the entrance by press-
ing the
button (control switch ON).
To work the electric door lock release press
the
button from monitors series Project
and PV 1211. For the FLAT PV2111 monitor
press the button to the right of the handset. In
the two or more entrance systems all the
audio and video communications and door
lock release, from one entrance to the other,
are automatically switched with the call or the
control switch ON.
In these systems the control switch ON from
the monitors can interrupt a running commu-
nication, for this reason it is advisable to
interrupt, by means of a relay art.1471, all the
control switches ON when the video system is
active, giving the priority of the communica-
tion to the door stations (see page 24).
Adjustments
All the regulations are carried out in the
factory. For possible corrections the inter-
vention of a specialized technician is advis-
able. The Contrast and Brightness adjust-
ments, being subject to the environmental
lighting conditions, are accessible from the
under-neath by means of a screw driver.
