flex7 Applications – PELV Absence Control + Tap-Off Unit With PELV Occupancy Control For Next Room

flex7 applications PELV Switching

Originally 1 large office. Reconfigured to create 2 separate spaces, requiring individual control; absence for the Office; occupancy for the Store Cupboard.

A flex7 tap-off box is plugged into the original box via a tap-off lead. The boxes now share the same supply, but require separate flex7 control modules.

Control of Office luminaires is via a flex7 plug-in sensor head and switches, all operating at PELV. The luminaires are manually switched on with a short pulse of either switch. They remain on whilst movement is sensed. After the room is vacated the luminaires switch off when the timeout period has elapsed.

Control of Store Cupboard 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.

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