- the separation of the supply line is achieved by a separation of the ground line.
- an electrical device 170 such as a loudspeaker, can advantageously be connected directly to the disconnecting device 120a. 170 speakers are connected. Separate connections in the supply line are therefore not required.

- the described loop-shaped energy supply with a separation function that can be activated by separation devices 220 thus enables a high supply reliability of the payloads connected to the supply line 210 to be achieved. This is advantageous in particular for voice alarm systems, since there is typically transmitted via the supply line, which simultaneously represents the wiring for the corresponding loudspeakers, a high electrical power in the form of alternating current with a low frequency.
