The terminal block Art. 1214/2C (if supplied separately) should be connected to the main riser of the system. If you are replacing an existing intercom, the necessary terminal block may already be present in the wall box; in this case, the supplied one can be kept as a spare.
5.2 Dipswitch Configuration
Before finalizing the connection, configure the 8 dipswitches located on the red socket of the interphone. These dipswitches determine the unit's address within the Simplebus 2 system.
