DESCRIPTION
Intelligent intercom with "door open/intercommunicating call" push button (key), bus relay (Art.2305) activation button (dot), "privacy ON-OFF" switch,
"door open" and "privacy on" LEDs and call tone volume control (3 levels). To reduce bus current all apartment devices are in a sleep mode when not
used. In case a user forgot to replace the handset, each operation must be executed within 10 seconds of lifting the handset otherwise the handset re-
turns to its sleep state. To then perform an operation it would be necessary to hang up the handset and pick it up again.
PUSH BUTTONS, LEDS AND CONTROLS (FIG.1)
a Door open push button – Intercommunicating call. For an intercommunicating call, pick up the handset and press as many times as the
extension or address value to call (see SW3 Intercommunication Settings).
b Activate bus relay board Art.2305 push button. To activate a bus relay pick up the handset and press as many times as the address val-
ue of the relay.
c Door Open LED. Switched ON if the door is open. Its operation depends on additional connections.
d Privacy ON LED. Switched ON when the privacy service is active
e Privacy ON-OFF switch. The privacy duration time can be programmed. If the intercom is programmed for a specific privacy duration,
after the service is enabled to "ON" (red LED ON), the service will automatically turn off when the time expires.
f Call tone volume control (3 levels)
DIP-SWITCHES AND JUMPERS (FIG.2)
SW1 Switches from 1 to 7 are used for unit address (from 1 to 127 binary coded). Last switch (8) is not used
SW2 Switches 1,2 and 3 are used to set privacy duration time. Switch 4 is not used.
SW3 Switches 1,2 and 3 are used to for intercommunication settings. Switch 4 is not used.

der.
PROGRAMMING
After each programming operation carried out through dip-switches or jumpers it is necessary to temporary disconnect the phone from the BUS or from
the power supply if locally powered.

The table above shows how to set the address of the phone. Considering that ON = 1 and OFF = 0, multiply each digit for the relevant decimal weight
then add values obtained to get the address: E.g. as highlighted in the table OFF,ON,OFF,OFF,ON, OFF,ON in binary is equal to 0100101 then adding
each digit for the relevant decimal weight you obtain the address 37.
Note
The maximum number of units allowed is 100 but the address of each unit can be a value between 1 and 127
