The bottom line: installers and facility managers who need a self-contained, line-voltage motion sensor that mounts with a high bay fixture will appreciate its straightforward operation and wide coverage; the single biggest reason to buy is the sensor's ability to switch loads directly at up to 45 ft mounting height, avoiding external power packs. The reviewer found setup clear and the sensing range effective for typical warehouse bays and large garages.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePIR occupancy detection:\u003c\/strong\u003e Passive Infrared sensing delivers reliable motion-based switching suited to high bay fixtures without false activation from wiring noise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-contained relay:\u003c\/strong\u003e The internal relay switches line voltage directly so there is no separate power pack required for operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with many lamps:\u003c\/strong\u003e Works with electronic and magnetic ballasts, CFLs, LEDs, and incandescent loads so it fits diverse lighting types in commercial spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e277V-capable:\u003c\/strong\u003e Accepts 277V standard installations, making it appropriate for commercial and industrial electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo minimum load:\u003c\/strong\u003e Operation without a minimum load requirement simplifies pairing with modern low-wattage LED fixtures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePush-button programmable:\u003c\/strong\u003e Simple on-unit programming and interchangeable hot and load wires ease installation and configuration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe CMRB 6 High Bay is aimed at electricians, maintenance crews, and facility managers who need a compact, on-fixture occupancy sensor for warehouses, gymnasiums, workshops, or large garages.
