New Square D® Wall-Mounted Occupancy Sensors Provide Customized Solution to Drive Energy Efficiency, Code Compliance

New Square D® wall-mounted occupancy sensors from Schneider Electric enable electrical contractors, consulting/specifying engineers and facility managers to readily achieve energy code compliance, reduce energy cost and prolong lamp life. Launching in mid-2008, the wall-mounted occupancy sensors will come in passive infrared (PIR) and ultrasonic models, along with a dual-technology model available exclusively from Schneider Electric. The sensors also incorporate an integral light-level sensor to prevent lighting from turning on when sufficient natural light is present, typically in windowed areas, providing increased energy savings, along with front-located adjustments for setting sensitivity and time delay, as well as an isolated relay for use with building automation, security and HVAC systems.

“Occupancy sensors are one of the most effective means to meet lighting control energy code requirements and achieve substantial energy savings with a typical payback period of three years or less,” said Scott Jordan, Square D lighting control product marketing manager. “These new non-obtrusive occupancy sensors give designers another option to optimize the sensors’ coverage patterns, especially in corridor areas.”

The three available models can be used to support specific application requirements. For example, the PIR device provides line-of-sight motion detection and is best-suited for areas like corridors and aisle ways. It is available with three interchangeable lenses to create custom coverage patterns:

• Wide-angle lens: 2,500 square feet at an 8-foot mounting height
• Long-range lens: 102 linear feet at a 10-foot mounting height
• High-bay lens: 54 linear feet at a 30-foot mounting height

With a 180-degree field of view and up to 1,000 square feet of coverage area, the ultrasonic occupancy sensor is ideal for multistall restrooms, open office areas and stairwells — primarily daylit spaces with obstructions in both commercial and residential applications and without flat ceilings that require greater minor motion coverage.

The dual-technology version employs both PIR and ultrasonic technologies, and provides the greatest sensitivity to motion in large areas with obstructions, such as classrooms, conference rooms, large meeting rooms or other spaces where minor motion coverage is critical. It employs PIR technology to detect major motion, and once lighting has been turned on, a combination of PIR and ultrasonic technology detects minor motion to keep lighting on while areas remain occupied.
