Occupancy sensing with dual relays provides selective control for multiple loads while maintaining illumination when needed. That translates to energy savings and reduced wear on lamps and ballasts. Use case includes corridors, lobbies, and classrooms where occupancy is intermittent. Flush-mount design simplifies retrofits, enabling quick installations in standard wall boxes and reducing disturbance to aesthetics and ceiling space—saving labor and minimizing downtime during upgrades. Wide load compatibility supports INC, HAL, MLV, ELV, and FLR loads on 120/277 VAC, including fluorescent and LED drivers, which translates to broad applicability across office suites and retail spaces without additional equipment. Three-way operation and dual-switch capability enable flexible control from multiple locations or zones, delivering consistent lighting behavior in conference rooms and open-plan offices while maintaining a simple wiring approach (wire leads). Certification and safety focus reduces compliance risk; cULus Listed NOM certification aligns with North American electrical codes, empowering safer retrofits and longer fixture life, while the almond color helps blending with standard décor. Overall, this device offers installation advantages, predictable maintenance intervals, and reliable performance in modern commercial lighting systems.

FAQs
The OSP10D-A is a flush-mounted occupancy sensor switch designed for single-pole 120/277 V circuits. It fits standard wall boxes and is ideal for corridors, offices, classrooms, and retail spaces up to about 1000 square feet. Its wire-lead wiring method simplifies retrofit projects and minimizes wall disruption while delivering reliable automatic lighting control.
The unit supports multiple load types including INC, HAL, MLV, ELV, and FLR, with rated power of up to 800 W at 120 V for incandescent/halogen, 1200 W for FLR at 120 V, and 2200 W for FLR at 277 V. This broad compatibility ensures reliable operation with various ballast and driver configurations common in commercial spaces.
Yes, the OSP10D-A supports three-way wiring, allowing control from multiple locations. This requires coordinating the dual-relay setup and proper wiring of line, load, and traveler conductors, but provides flexible control in larger spaces such as conference areas and open offices without sacrificing performance.
The device is cULus Listed and NOM certified, indicating compliance with key North American safety standards. This reduces regulatory risk during installation and supports safer retrofits in commercial environments where energy management is a priority.
By automating on/off control based on occupancy, the OSP10D-A minimizes wasted lighting and extends lamp life, leading to lower energy bills and reduced maintenance cycles. Its robust construction and compatibility with common commercial ballast types help maximize uptime and predictable performance across facilities.
