Videointercom systems
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 corre-
sponding video intercom and it activates the
system for a time of about 100 seconds. The
images appear on the video intercom a few
seconds after the call.
If in the meantime another call occurs, the video
intercom shuts itself OFF and connects the last
call. The system switches OFF automatically
after 100 seconds.
In case more calls occur simultaneously, a
protection circuit against overloading and short
circuiting is provided to disable the timer and
therefore to shut OFF the system.
In the absence of calls from the door station,
from any video intercom (if provided in the
system) it is possible to control the entrance by
pressing the
button (control switch ON).
To work the electric door lock release press the
button from video intercoms.
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
video intercoms can interrupt a running com-
munication, for this reason it is advisable to
interrupt, by means of a relay. This function
when the video system is active, giving the
priority of the communication to the door sta-
tions for some examples from page 68 on-
wards.
WORKING INSTRUCTIONS
Intercommunicating systems
The switch between door station or
intercommunicating devices is automatic after
receiving a call (from door station or from
another intercommunicating device) or by
pressing the button “
” from video-intercoms.
By pressing the button “ ” from intercoms or
videointercoms electric look release is oper-
ated and automatically the system switches to
the door station side. During an intercommuni-
cating conversation between two devices, it
would be possible from the external door sta-
tion to call other apartments.
During an intercommunicating conversation
between two devices an incoming call from the
door station to one of the two devices will
automatically switch the communication to the
door station.
All the devices with intercommunicating
features, when they are in communication with
the door station, do not have privacy between
them. On the contrary, the privacy with other
apartments is guaranteed.
Installing several art. 1443ED in a multi ways
installations allows to have the intercommuni-
cating service between apartments with pri-
vacy towards the door station.
At the end of a communication art.1443ED
remains switched to the side from which the
last call has been originated.
Red LED shows that the switching module:
- is switched to the side of door station when it
lights-ON
- is switched to the intercommunicating side or
there is no power when it lights-OFF.
Intercom systems
For all the intercom systems, simply lift the
handset to speak to the door station.
The call is indicated by a sound signal on the
loudspeaker of the handset. If the handset of
the intercom is not properly hung-up the sound
is not reproduced.
To activate the door release, press the push-
button with the key symbol.
In systems with two or more entrances the
communication and door release are switched
automatically on the entrance from which the
call is made while the other entrances are
isolated.
Adjustments
All the regulations are carried out in the factory.
For possible corrections the intervention of a
specialized technician is advisable.
The Contrast, Colour and Brightness adjust-
ments, being subject to the environmental light-
ing conditions, are accessible from the under-
neath by means of a screw driver.
