The circuit diagram in Figure 2 illustrates a bell system with the following components:

• A 240V/12V transformer steps down the voltage from 240V to 12V.
• 12V Bell 1 is connected to the 12V output of the transformer, with connection points A and B. Associated dimensions are 200 mm, 150 mm, and 180 mm.
• A 240V Relay has its coil connected to the 12V output of the transformer via connection points C and D.
• 12V Bell 2 is connected through the contacts of the 240V Relay and is also powered by
