INSTALLATION
1. Make the system wiring duct reach the hole on the bracket. The recommended height is from 1.48 to 1.52
from the fi nished fl oor.
2. Fasten to the wall using the 4 screws provided and make the central gap of the bracket coincide with
either the previously walled-in embedding box (where applicable) or with the wire protruding from the
wall.
3. Connect the wires to the terminal board on the bracket.
4. Fit the monitor to the bracket by engaging the upper hooks fi rst and then turn it to lock it using the
automatic fastener hook. To remove it from the bracket, pressure the fastener shown in
fi gure 3
and
reverse the operation.
CONNECTIONS
A terminal board for wiring the following signals is found on the bracket:
1:
System
earth
3:
Monitor power positive
A:
Negative video input
B:
Positive video input
E:
Monitor auto power-on
C:
Audio, call and door opener input
T:
Input for monitor operation without ringer
P:

Connect the wires as show in the diagrams attached to the video unit for correct operation of the monitor.
Wires 1-3-A-B-C must be connected for correct system operation.
Description of auxiliary connections
The connections described here provide the following auxiliary monitor functions.
•
Terminal E
, if connected, is used to switch the monitor and the camera on by pressing the button with the
“
•
“ symbol on the monitor. The function is available only if no other monitor is on.
•
Terminal T
, if connected, is used to switch the monitor on without operating the ringer. This function is
available by supplying -12V voltage between T and 1 when a voltage of +20V is present on terminal 3.
•
Terminal P
is used to fl oor calls. A A70 IRC (AV7362) power supply unit is required for this function to take
the auxiliary call signal to the column. Alternatively, use an A3000 (AV1142) auxiliary power supply unit .
•
Terminal LD
makes it possible to use the red LED on the monitor. The LED will light up when a po12V
continuous voltage is applied. This voltage must be referred to the system earth (“
1
”).
The red LED may be used to indicate open door conditions or, connecting terminal
LD
to terminal “
3
” it may
be used to indicate when the system is working and consequently that auto power-on is not possible.
When the monitor is on, the same LED will light up with green light and this colour will prevail on external
indications, if any.
Set the monitor correctly (see monitor manual) and p12V direct voltage to terminal
LD
to make the
red LED light up indicating muting function (
MUTE
).
•
Terminals Q1 and Q1
make the normally open clear contact of button “
A
” on the monitor available. This
may be used, for example, to operate staircase lights, cameras, electrical gates, etc.
•
Terminals Q2 and Q2
make the normally open clear contact of button “
B
” on the monitor available. This
may be used, for example, to operate staircase lights, cameras, electrical gates, etc.

Chaque interrupteur prend une valeur différente selon sa position (voir illustration au tableau
ci-dessous).
Pour élaborer un code quelconque, il est nécessaire de positionner sur
OFF
les interrupteurs dont la somme des
valeurs donne le code désiré et de positionner sur
ON
ceux qui ne sont pas concernés par l’opération.
Exemple de codage du code 13 équivalent à : 1 + 4 + 8 = 13
Pour programmer le code 13 qui est obtenu en additionnant les valeurs 1, 4 et 8, il est nécessaire
de positionner sur
OFF
les interrupteurs correspondants qui, selon le tableau précédent, correspondent
respectivement au premier, au troisième et au quatrième interrupteur. Les interrupteurs restants seront laissés
