Abstract
An occupancy sensor is provided with a housing having an interior cavity. A switch is mounted in the interior cavity of the housing and configured for placement in the open and closed positions. A fascia cover plate may be positioned on the housing to enclose the interior cavity. The fascia cover plate has a fascia rib on an interior surface thereof. The fascia rib is arranged to interfere with the switch in the disabled state to prevent positioning of the fascia cover plate on the housing.
Claims9
An occupancy sensor to detect occupancy of a controlled space, comprising:
- first and second ultrasonic transducers oriented above a lens;
- and
- a fascia cover plate to cover said transducers, the fascia cover plate having grillwork to allow transmission of ultrasonic energy between said ultrasonic transducers and the controlled space;
- wherein said first ultrasonic transducer is in a substantially parallel orientation with said second ultrasonic transducer and said transducers are arranged in close proximity to the grillwork to enhance the effectiveness of a wave pattern of the ultrasonic energy.
An occupancy sensor to detect occupancy of a controlled space, comprising:
- a first ultrasonic transducer having a first longitudinal axis and a second ultrasonic transducer having a second longitudinal axis parallel to said first longitudinal axis;
- a fascia cover plate covering said transducers, said cover plate having grillwork to allow transmission of ultrasonic energy between at least one of said ultrasonic transducers and the controlled space;
- wherein at least one of said ultrasonic transducers is substantially adjacent to the grillwork to enhance the effectiveness of a wave pattern of the ultrasonic energy;
- and
- a dividing rib adjacent said fascia cover plate and disposed between said ultrasonic transducers.
