Private Private Office Lighting Plan Design Solution Description The DT-200 dual technology occupancy sensor, wired to a BZ-100E-P power pack, is used to automatically turn lights off when the room is unoccupied, and turn lights on upon occupancy. The sensor is mounted in the corner, to prevent a view out the doorway that might otherwise result in false activations. Two wall switches are used for bi-level switching, to manually override off for individual lamps within the fixtures. A third wall switch is used for switching wallwash lighting off. The Isolé plug load control is used at the work station for turning off plug loads when the office is unoccupied. The personal sensor is mounted to the underside of the binder bin, so that it is not facing the door, and is facing the primary work area.
