POWER SUPPLY INSTALLATION
The power supply must be installed in a dry place away from direct heat or dust.
Ensure easy access for inspection and maintenance. Secure the unit to the wall
with the anchor bolts provided or insert it into a rack with a omega DIN bar. Be-
fore connecting the unit use a tester to make sure that the cables are not broken
or short-circuited. For user safety, the equipment operates at a low voltage and
is separated from the mains by a high-insulation transformer. We recommend
installation of an overload cutout of appropriate capacity between the mains and
the unit. To complete the installation, proceed as follows:
1) Make the cabling connections to the terminal block in accordance with the
diagrams enclosed with this manual.
2) Connect up the power terminal block located beneath the rear cover.
3) Power up the power supplier. Once correctly powered up, only the red
“power-on” LED L6 for the entrance panel and interphones must be illumin-
ated.
The same rule also applies to all the other units in the system.
GENERAL CABLE INSTALLATION INSTRUCTIONS
Correct DIGIBUS installation requires the following factors to be taken into ac-
count:
-
the installation site
-
the size of the installation
The equipment is fully compliant with the “CE” mark and directives 2004/108/
EC and the following regarding the Community safety standards and the elec-
tromagnetic compatibility. Nonetheless, for correct installation, the following pre-
cautions must be taken:
-
the system cables must be layed taking into account the overall length of the
system cabling; the cross-section of the cables increases with the overall
length of the installation as shown in the tables given below.
-
the cables connecting the external/internal units and the power supply must
not be run together with power cables (230V or greater), but must be in-
stalled in their own ducts.

Description of power supplier terminal functions:
CH
Call signal activation control line.
This terminal is used by the entrance panels or switchboard to activate
the call generator in the power supplier. When terminal CH is shorted to
terminal 4, the call signal is activated by terminal 3. The signal remains
active for the time terminal CH is short-circuited.
S
Door lock release control line.
This terminal is used by the entrance panels or switchboard to release
the door lock for the corresponding entrance panel or switchboard.
When terminal S is shorted to terminal 4, terminal S1 is shorted to
terminal 0 (15V rectified) and LEDS L1 and L2 illuminate. Terminal S1
remains shorted for the time terminal S is activated.
F1
Auxiliary function 1 activation control line.
This terminal is used by the entrance panels or switchboard to activate
function F1. When terminal F1 is shorted to terminal 4, the voltage at
terminal R1 increases to 12 Vdc and remains at this voltage for the time
terminal F1 is shorted. Activation of the function is signalled by illumina-
tion of LED L3.
F2
Auxiliary function 2 activation control line.
This terminal is used by the entrance panels or switchboard to activate
function F2. When terminal F2 is shorted to terminal 4, the voltage at
terminal R2 increases to 12 Vdc and remains at this voltage for the time
terminal F2 is shorted. Activation of the function is signalled by illumina-
tion of LED L4.
3
Phonic and call signal line.
This terminal routes the call signal along the cable riser and signals the
presence of units with the handset raised (engaged). When terminal
CH is activated, a modulated call signal is transmitted by terminal 3 and
LED L5 illuminates. When terminal CH is de-activated, the line con-
nected to terminal 3 indicates the presence of one or more interphones
with the handset raised (engaged) by illumination of LED L5.
4
Digital circuit power line (negative).
5
Digital circuit power line (+ 13.5 Vdc 1,5A).
Energisation of terminal 5 is indicated by illumination of LED L6.
4
Auxiliary function power line (negative).
R1
Auxiliary function 1 power line (+ 12 Vdc 0.15 A).
This terminal activates a relay when function F1 is activated. When ter-
minal F1 is activated, terminal R1 is powered by a 12 Vdc voltage.
4
Auxiliary function power line (negative).
R2
Auxiliary function 2 power line (+ 12 Vdc 0.15 A).
This terminal activates a relay when function F2 is activated. When
terminal F2 is activated, terminal R2 is powered by a 12 Vdc volt-
age.
S1
Door lock release line (1A).
When terminal S is activated, terminal S1 is
shorted to terminal 0 and LEDS L1 and L2 illumin-
ates.
The line is protected by a fuse F 3,15AL 250V
(F2)
15-0 15V (rectified) line:
These terminals power the illumination lamps, door lock and services.
1A door lock release.
The line is protected by a fuse F 3,15AL 250V (F2)
PRIM Power terminals: 230 Vac +6/-10% 50-60Hz.
These terminals are mounted under the thermoplastic protection
marked by the symbol
and are used to power the relay connec-
tions. No earth terminal is fitted, this being a power supplier constructed
to Class 2 specifications.
