5. Installazione e configurazione

Before beginning installation, ensure the power to the Simplebus 2 system is disconnected. It is highly recommended to take a photograph of the existing wiring connections before disconnecting any wires, as this will aid in replicating the setup.

5.1 Collegamenti di cablaggio

For Simplebus 2 systems, connect the two system wires to the terminals labeled L E L on the interphone. Polarity does not matter for these connections. If replacing an old intercom, you may replicate the color coding of the wires from the previous unit.

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.

Each dipswitch can be set to either ON (up position) or SPENTO (down position). Refer to the system's addressing table (usually provided with the main Simplebus 2 system documentation) to determine the correct configuration for your specific unit number.

Exampon: To set the interphone address to 25, configure the dipswitches as follows:

• Dipswitch 1: ON (UP)
• Dipswitch 2: OFF (DOWN)
• Dipswitch 3: OFF (DOWN)
• Dipswitch 4: ON (UP)
• Dipswitch 5: ON (UP)
• Dipswitch 6: OFF (DOWN)
• Dipswitch 7: OFF (DOWN)
• Dipswitch 8: OFF (DOWN)
