T Occupancy Sensor Sensing Technology Passive Infrared PIR/Microphonic Operating Voltage 277V… and 1 more item

W W Grainger Inc was awarded contract A207_PO-0454868 by the University of Virginia on July 4, 2026, with a cumulative contract value of $744. The contract encompasses the procurement of occupancy sensing and lighting control equipment for delivery to George Settle. The contract includes three occupancy sensors utilizing passive infrared and microphonic sensing technology, rated for 277 volts maximum operating voltage with a maximum coverage area of 500 square feet and 15-foot mounting height capacity. Each sensor carries a load rating of 120 volts alternating current at 800 watts/6.67 amperes for incandescent applications and utilizes hard-wire communication methodology, priced at $103.75 per unit.

The contract also specifies the procurement of four fluorescent lighting dimmers operating at 120 to 277 volts alternating current with slide on/off and slide dimming switch functionality. The dimmers are rated for 120 volts alternating current at 8.0 amperes for fluorescent ballast applications and 277 volts alternating current at 8 amperes, finished in white, with no neutral wire requirement, at $108.30 per unit. These occupancy sensing and lighting control components are typical of energy management system upgrades for institutional facilities.
