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.
SW1 DEVICE ADDRESS
SWITCHES STATUS BINARY CODE DECIMAL VALUE ADDRESS

The table above shows how to set the address of the device. Considering that ON = 1 and OFF = 0, multiply each digit for the rele-
vant decimal weight then sum the 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 multiplying each digit for the relevant decimal weight you obtain the address that is 37.
Note: the maximum number of units allowed is 100 but the address of each unit can be a value between 1 and 127.

OFF OFF
Intercommunication allowed between units (same unit address) inside the same
at. To call an extension pick up the handset then press the “door open” button as
many times as the extension value (Eg. extension 2 two times, 3 three times etc).
Each intercom/videophone in the same apartment must have a dierent
extension address, the master address must always be set except when one
of the intercom/videophone is set for apartment intercommunication (i.e. in
a 3 intercom/videophone installation, one of the intercom/videophone must
have the extension address 1 while the others must have dierent addresses).
1 (master)
ON OFF
2 (slave)
OFF ON
3 (slave)
ON ON
4 (slave)
ON OFF OFF
Intercommunication allowed between videophones (dierent apartment). To
call an extension pick up the handset then press the “door open” button as many
times as the address value (Eg. extension 10 ten times, 12 twelve times etc)
NOTE: Extension 1 is mandatory. On systems with more than one device in an apartment, each device must have a unique extension ID.
On installations where there are more than one intercom/videophone in the same apartment and intercommunication be-
tween dierent apartments is required, only one intercom/videophone may be set with this function (SW3.1=ON, SW3.2=OFF,
SW3.3=OFF). The other intercom/videophones in the apartment must be set for local intercommunication with extension ad-
dresses “2-4” (slaves). From the intercom/videophone set for intercommunication with other apartments it will be not possible to
intercommunicate within the apartment but slave extensions 2-4 will be able to intercommunicate with each other.
NUMBER OF RINGS
The number of rings can be set to 3 (factory preset) or 6. To change the number of rings proceed as follow:
• Disconnect the power supply from the system;
• Short the terminals “LB” and “GND”;
• Reconnect the power supply to the system checking the privacy on LED and then remove the short between terminals “LB” and “GND”;
• The number of LED ashes will be 1 for 3 rings or 2 for 6 rings.
Each time this operation is carried out the number of rings is switched between the values 3 and 6.
SIGNALS ON CONNECTION TERMINALS

terminal and the relevant GND terminal)
