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 of the lamps in the luminaires. A third wall switch is used for switching wallwash lighting. The Isolé plug load control is used at the workstation for turning off plug loads (including task lighting) 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. For applications not requiring the isolated relay for integration with HVAC or BAS, use a WPIR occupancy sensor.
