Two Offices, either side of a central Corridor, all protected by different devices at the distribution board (could be different phases); all three requiring individual occupancy control.

Control of both Offices and Corridor luminaires is via separate flex7 plug-in sensor heads operating at PELV. The luminaires are automatically switched on when movement is sensed. After the room is vacated the luminaires in that room switch off when the time-out period has elapsed.

The emergency luminaires are tested via a hard-wired 230V key switch, often located in close proximity to the distribution board.

The addition of a plug-in Corridor Hold facility means that the corridor luminaires are held on whilst either of the Offices are occupied. Crucially, movement detected in the corridor has no effect on the Office luminaires.
