PRIVACY DURATION
• Keep pressed the button until the two LEDs and are switched on.
• Press the button for the number of times corresponding to the required privacy duration to set. Each time the button is
pressed, the duration is increased by 15 minutes: i.e. to set 2 hours, press the button 8 times.
• Once the required privacy time is reached, wait approx 5 seconds for the two LED’s to switch off. The new duration is set.
VIDEOPHONE ADDRESS – SW1.1..7
SW1.1..7
The table below shows how to set the address of the videophone. Considering that ON = 1 and OFF = 0, multiply
each digit for the relevant decimal weight then sum 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 dec-
imal weight you obtain the address that is 37.
SWITCHES STATUS BINARY CODE - DECIMAL WEIGHT ADDRESS
7 6 5 4 3 2 1 64 32 16 8 4 2 1
OFF OFF OFF OFF OFF OFF ON 0 0 0 0 0 0 1 1
OFF OFF OFF OFF OFF ON OFF 0 0 0 0 0 1 0 2
OFF OFF OFF OFF OFF ON ON 0 0 0 0 0 1 1 3

OFF ON OFF OFF ON OFF ON 0 1 0 0 1 0 1 37
ON ON ON ON ON ON ON 1 1 1 1 1 1 1 127
Note: The maximum number of units allowed is 100 but the address of each unit can be a value between 1 and 127.
POWER SUPPLY VERSION WITH MEMORY BOARD
If the videophone is the only indoor station installed in the system (i.e. one way videokit)
the additional power supply unit it is
not required. Set the dip-switch 8 to ON position to enable the supply from the BUS. In position OFF, the memory board supply must
be provided by a local 12Vdc power supply unit like slave videomonitors (see
“Slave switch on mode - SW3.4” on page 23
).
Note: do not set dip-switch 8 to ON for more than one videomonitor on the same BUS line.
VIDEOPHONE END OF LINE TERMINATION – JP1
Looking at the videophone from the rear:
Move the switch JP1 to the upper posi-
tion to enable the bus termination.
Move the switch JP1 to the lower posi-
tion to disable the bus termination.
In case of more units (intercoms, videophones or video monitors) in a parallel connection (bus wires are connected to the terminals
of the first unit then from this to the second and so on up to 4 units max) the BUS termination must be enabled only for the last unit
in the chain while on all other units it must be set to disabled.
INTERCOMMUNICATION MODE – SW3.1
SW3.1
This switch establishes the intercommunication mode: in OFF position (default) intercommunication is between units
in the same apartment (same addresses but different extension); in ON position the intercommunication is between
units in different apartments (different addresses).
On installations where there are more than one intercom/videophone in the same apartment and intercommunication
between different 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 addresses “2-4” (slaves). From the intercom/videophone set for intercommunication with other apartments it
will not be possible to intercommunicate within the apartment but slave extensions 2-4 will be able to intercommunicate
with each other within the apartment.
EXTENSION NO – SW3.2..3
SW3.2..3
If the intercommunication between apartments is enabled (switch 1 of
SW3
= ON)
leave these two switches in default position (both to OFF). Otherwise, if the inter-
communication is between the same apartment (switch 1 of
SW3
= OFF), set the
extension addresses starting always from 1. During the external call, all video monitors in the same
flat will ring but the video will be shown only from the videophone with extension address 1.
2 3 EXTENSION NO.
OFF OFF 1 (default, master)
ON OFF 2 (slave)
OFF ON 3 (slave)
ON ON 4 (slave)
