Go to 2N® IP Intercom's web management - section Hardware - Switches and set the Switch code you want to use for activating the switch from 2N® Indoor Talk
Make sure that the electric opener/lock is always connected to the intercom's 12V output using a security relay to make the installation safe. The motherboard relay is used for switching lights or other peripherals that do not have to be secured.
It is always recommended that the 2N® Security Relay (Part No. 9159010) is used for increased security.
