UW-200-I, Wall Switch Occupancy Sensor

UW-200-I Wall Switch Occupancy Sensor – Ultrasonic Dual Relay Lighting Control The UW-200-I is an ultrasonic wall switch occupancy sensor designed for controlling two independent lighting loads or circuits. It uses 40kHz ultrasonic technology to detect occupancy and automatically turn lights ON or OFF based on presence. Ideal for applications such as individual restrooms, storage rooms, or spaces with partially obstructed views, this sensor supports bi-level switching and daylight control to optimize energy savings. Suitable for electrical distributors and lighting solutions providers, it integrates easily into standard single-gang wall boxes and complies with energy codes requiring occupancy and daylight control. Specifications Voltage: 120/277 VAC; 50/60 Hz Load Rating: 0-800 W ballast or tungsten @120 VAC, 1/6 HP; 0-1200 W ballast @277 VAC Sensor Frequency: 40 kHz ultrasonic Time Delay Settings: 5 to 30 minutes, including walk-through and test modes Coverage: Major motion 20’ x 20’, Minor motion 15’ x 15’ Dimensions: 2.73” x 1.76” x 1.83” (69.3mm x 44.7mm x 46.5mm) L x W x D Finish: Ivory Mounting Type: Wall mount, single-gang box compatible UL and cUL Listed Product Weight: 4.75 lbs Five-year warranty Features Two relays for independent control of separate lighting loads or circuits Selectable Manual-ON or Auto-ON operation for each relay Built-in light level sensor provides daylight control on secondary relay to hold lights off when adequate daylight is present Selectable walk-through mode reduces light ON time after brief occupancy Test mode for quick sensor adjustment and commissioning Selectable audible and visual alerts warn before automatic shutoff Zero-crossing relay switching for extended relay life Sensor coverage tested to NEMA WD 7 guidelines Compatible with industry standard decorator wall plates (sold separately) Service mode allows operation as a manual service switch in case of sensor failure Ultrasonic sensitivity adjustable via trimpot for fine-tuning detection range LED occupancy indicator for visual confirmation of sensor status Downloads & Links Installation/Operator Specification/Technical Other 1 Brochure
