WattStopper CU-250-A Ultrasonic Occupancy Sensor

Description:

The Wattstopper CU-250-A Occupancy Switch is an ultrasonic multi-way wall switch vacancy sensor designed to provide manual-on and automatic-off lighting control in residential and commercial applications. Using 40 kHz ultrasonic sensing technology, the device detects occupancy without requiring a direct line of sight, making it ideal for enclosed spaces, bathrooms, L-shaped rooms, storage areas, and locations with obstructions. The CU-250-A supports multi-way switching, adjustable sensitivity, and adjustable time delays while helping reduce energy consumption through automatic lighting shutoff. It is designed to comply with energy efficiency requirements including California Title 24 standards.

Applications:

The Wattstopper CU-250-A Occupancy Switch is commonly used in bathrooms, storage rooms, utility rooms, L-shaped rooms, hallways, offices, commercial spaces, educational facilities, healthcare environments, and other indoor applications where automatic lighting shutoff, occupancy-based control, energy savings, and multi-location switching are required. Its ultrasonic sensing technology allows reliable operation in areas where furniture, partitions, or room layouts may obstruct direct sensor visibility.
