Abstract:
An electrical device is described having surface mounting structure for mounting the electrical device in one of at least three different mounting patterns. In one embodiment, the electrical device is a lampholder having an occupancy sensor. In this embodiment, the occupancy sensor defines a coverage area and an un-coverage area when the lampholder is mounted to a surface, such as a ceiling, via the surface mounting structure; and, the surface mounting structure includes four sets of keyholes enabling the lampholder to be mounted to fasteners on the surface in one of a plurality of different mounting patterns for positioning the un-coverage area in a desired location, such as, for example, opposite the closest entry point to a room. The coverage area corresponds to a detection field of the occupancy sensor. Motion in the detection field is detected by the occupancy sensor.
