Cooper Wiring Devices OS310R-W Occupancy Sensor Switch

Product Description

The COOPER WIRING DEVICES OS310R-W is a passive infrared occupancy sensor dual switch designed to automatically control lighting loads based on detected motion. Rated for use at 120 volts AC, it supports incandescent and fluorescent loads up to 1,000 watts each, plus CFL, LED, halogen, electronic low voltage, and magnetic low voltage fixtures. The sensor delivers a 180-degree detection pattern covering up to 1,000 square feet with a manual delay adjustment to fine-tune the off-delay timing. Electricians install this device as a direct wall-switch replacement in residential and light commercial applications where automated occupancy-based lighting control is required.

The OS310R-W is suited for offices, classrooms, conference rooms, restrooms, and other spaces where lights are frequently left on unnecessarily. Its dual-switch format allows control of two lighting circuits or a combination of switched and occupancy-controlled loads from a single device location. The manual delay adjustment makes it straightforward to configure hold times on-site without additional tools. The white finish matches standard decora-style wall plates commonly used in commercial interiors.

Compatibility

Designed for use with CFL, electronic low voltage, fluorescent, halogen, incandescent, LED, and magnetic low voltage fixtures at 120 volts AC. Suitable as an occupancy-sensor wall-switch replacement in standard single-gang or multi-gang electrical boxes per applicable NEC installation requirements.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Turn off circuit power at the breaker and verify the circuit is de-energized with a non-contact voltage tester before wiring. Mount the device in a standard wall box and set the manual delay adjustment after installation to match the occupancy pattern of the space. Do not exceed the rated load capacity for any fixture type connected to the switch.
