2.3 Connection

Line :
The basic functionality of intercom (voice communication) needs connection of telephone line only. When
you connect the line, the Link Smile DoorPhone announces by sound signal.
We not recommend connecting the Link Smile DoorPhone in parallel with other analog phone.
Attention: The line is necessary to program the Link Smile DoorPhone by the software.
12V Power supply:
The power supply might be AC and also DC, not depends on polarity. For 12V, the max consumption is
250mA. Power supply might be used also for electrical lock powering. Then we recommend power supply
12V/1A. You can also use 24V DC power supply. It is useful mainly at installations where power supply is
already installed and it is used for sliding doors, RFID, etc..
Attention: The power supply is necessary for the correct operation of the relay.
Relay :
The Relay have many possibilities in practice usage. The 12V power supply must be connected for
correct operation. The intercom unit has galvanically isolated all important parts. Telephone line is
isolated from power supply and relay contacts are also galvanically isolated from other electronic parts.
In any case must not be activated directly main voltage 120V or 230V ! When you need control
main devices please use contactors (power relays).
