The zone unit includes a semiconductor switch capable of electrically connecting the downstream unit to a power supply, and a zone power supply driver capable of waking up the zone unit in response to reception of an unique identifier transmitted from the central unit. The downstream unit is woken up when the semiconductor switch of the zone unit enters an ON state.
