Electrical door lock
The video signal may
be disturbed during the
operation of the electrical
lock. To avoid this prob-
lem or actuate locks with
characteristics other than
recommended (12Vac
1A max.) an additional
power supply should be
used as indicated in the
diagram below.
It is also recommended to connect
one interfer-
ence suppressor
(transil) as close as possible to
the terminals of the electrical lock.
* Letters for reference on the diagrams (see pages 7 and 8)
** The sum of all the sections “E” must not exceed 300 meters.

Art.2302 Farfisa cable
Twisted pair cable specified for the digital instal
-
lation with DUO systems. The use of inappropri-
ate cables may have an adverse effect on the
performance of the system.
Technical characteristics
Number of conductors: 2
Colour:
red and black
Cross-section:
2x1mm² (AWG17)
Material:
tinned copper
Twisting pitch:
40mm
Nominal impedance: 100W
Connection of a supplementary
ringing bell or a lamp signaler for
the incoming calls
12Vac; 12÷24Vdc - 1A
By applying a self-powered ringer between
terminals C and NO it is possible to drive to
another room the calls received by the switch-
board.
- Contacts C and NO of the relay are open in
idle state and closed in activation mode.
- Contacts C and NC of the relay are closed in
idle state and open in activation mode.
It is possible to program the ON time of the
relay, acting in the proper submenu in the “ad-
vanced settings” menu.

(for a proper installa-
tion and connection please refer to the technical manual of wall bracket)

monitor.
Connection of a CCTV monitor
Attention!
Please use a monitor with no earth connection (Class II) or
use a ground loop separator. CCTV monitor can work either in continu-
ous or timed mode. In the case of continuous mode (direct powering
from the main) monitor is still powered-ON also when the door station is
not connected (no image).
In timed mode monitor is powered-ON only when the door station is in
connection (with image). To operate in this way it is necessary to con-
nect the CCTV monitor as shown in the following diagram and program
the internal relay of switchboard as reported in the chapter “Operating
mode of internal relay”
(see pag.14).
