Ceiling Mount Occupancy Motion Sensor, SWX-221-1, Passive Dual Technology Detection, PIR & Acoustic, Large Motion Detection - 360 Degree, 12-24 VDC Low Voltage, Made in The USA

Advanced Dual Technology Detection: Sensor combines Passive Infrared (PIR) motion and acoustic detection technologies, providing superior occupancy detection in spaces with obstructions or where people are stationary for long periods of time.
Low Voltage Operation: Operating at 12-24 VDC, this sensor requires connection to a power/relay pack (not included) to control lighting. This feature enables connection with other low voltage sensors in order to together provide adequate coverage of large or irregular shaped areas. SENSORWORX model SWX-900 or SWX-900-AX are the recommended power / relay packs.
Compact and Unobtrusive Design: Featuring a sleek 4.00 diameter and 1.25 height with a matte finish, the SENSORWORX ceiling motion sensor is both compact and aesthetically pleasing, ideal for maintaining the décor of modern spaces. White indicator LED can be disabled.

Screw holes are also provided for direct attachment to ceilings or 3.5 inch octagon j-boxes or mudrings with 1.75 inch hole spacing.
Large Motion Detection: Provides ~2000 sq ft of Passive Infrared (PIR) motion coverage from mounting heights between 8-15 ft. Best choice for detection of large motions like walking. Recommended for use in hallways or open offices. For larger areas, multiple units can be used together with one power/relay pack.
Additional Features: Device allows user to easily modify its configuration settings like time delay. Settings are changed via a short push-button sequence that can be done safely in seconds via a push button under the cover.
Quality and Compliance: Proudly made in the USA, 5-year warranty. UL Listed, RoHS Compliant, BAA Compliant, BABA Compliant, TAA Compliant, Meets ASHRAE 90.1, IECC, and Title 24.
