VIDEO SIGNAL STABILISATOR
On the rear of the interphone there is a con-
nector (A-B-C) and a jumper for the video
signal balance. This jumper must be used on
the installations where there are more applian-
ces (interphones or monitors) connected in
series (Fig. 5) or with star connection (Fig. 6).
On the standard configuration displace the
jumper into "Terminazione
(Termination 100 Ohm) only on the last set and
keep the jumpers on the other appliances in
the initial position "Nessuna terminazione" (No
termination" (Fig. 5).

If the image shown on the monitor is distorted, displace the jumper into
one of the alternative positions to the initial one (100 Ohm or 50 Ohm),
so as to eliminate the distortion.

On installations with several
appliances (interphones or
monitors) with star connec-

PROGRAMMING
There are three interphone programming modes: assignment of an iden-
tification code or call code (indispensable), assignment of a secondary
identification code (for interphones associated with a master interpho-
ne), programming of pushbuttons for auxiliary services and intercommu-
nicating calls (when necessary).
Programming must be performed with the system switched on, without
active communication and only after connecting the interphones/moni-
tors to the system and programming the panels.
Identification code programming
The identification code is programmed via an entrance panel (MASTER),
already configured and present on the system.
The interphone is supplied without associated identification code. To
verify this condition, press the lock release pushbutton and the interpho-
ne should emit a triple "Beep".
Programming phase:
1) Remove the interphone cover.
2) Press and hold the RESET pushbutton on the interphone.
3) Press and hold the tab on the lock release pushbutton, together with
the RESET pushbutton.
4) Release the RESET pushbutton, keeping the lock release pushbut-
ton pressed.
5) After 2 seconds the interphone emits a high tone and communication
is enabled with the panel. If the monitor is also connected to the inter-
phone, it is switched on and connected to the camera of the entran-
ce panel.
6) Release the tab of the lock release pushbutton.
7) On pushbutton entrance panels, press the call button for the inter-
phone, while on alphanumeric keypads, enter the call code and press
pushbutton " ".
8) If the system contains an interphone that already has the same asso-
ciated identification code, the panel emits a low signal and the ope-
ration should be repeated from point 2.
9) Otherwise the code is associated with the interphone and communi-
cation is terminated.
Secondary identification code programming
Programming of the secondary identification code is only required when
more than one interphone is to be called by means of the same pushbut-
ton or call code. The interphones that ring at the same time are associa-
ted with the same group. The "master" interphone is programmed first by
means of the "identification code programming" procedure described
above, while the additional group interphones are programmed with the
secondary identification code.
A maximum of four interphones can be associated with the same group,
without the need for programmer type 950C.
If the interphones are combined with Petrarca monitors, an additio-
nal power supply type 6923 must be fitted for each additional moni-
tor after the second monitor. Using programmer type 950C, activa-
tion of the ringtone on all monitors can be programmed, without
simultaneous activation of all monitors, to then enable activation of
the monitor from the interphone used to answer the call with the
self-start pushbutton; this avoids the need to use additional power
supplies.
Programming phase:
1) Remove the interphone cover.
2) Press and hold the RESET pushbutton on the interphone.
3) Press and hold the tab on the lock release pushbutton and the self
start/auto-activation pushbutton (the first pushbutton below the tab),
together with the RESET pushbutton.
4) Release the RESET pushbutton, keeping the other two pushbuttons
pressed.
