Control of the luminaires is via a flex7 plug-in sensor head operating at PELV. The luminaires are automatically switched on when movement is sensed. After the room is vacated the luminaires switch off when the timeout period has elapsed.
Installation time is dramatically reduced as everything plugs-in, meaning only the 4 conductors at the Distribution Box require on-site termination.
Note: emergency luminaires are tested via a hard-wired 230V key switch, often located in close proximity to the distribution board.
