WattStopper WT-2255 Ultrasonic Occupancy Sensor

Description:

The WattStopper WT-2255 Ultrasonic Occupancy Sensor is a ceiling-mounted occupancy sensor designed to automatically control lighting, HVAC equipment, and other building systems based on occupancy detection. Operating on 24 VAC/VDC and utilizing 32 kHz ultrasonic sensing technology, the WT-2255 provides 360-degree, two-sided coverage with a sensing range of up to 90 linear feet. The sensor incorporates advanced signal processing circuitry to improve detection accuracy and reduce false activations, while its isolated relay output allows integration with lighting controls, energy management systems, and building automation equipment.

Applications:

The WattStopper WT-2255 Ultrasonic Occupancy Sensor is commonly used in open office areas, warehouses, hallways, conference rooms, educational facilities, healthcare buildings, commercial offices, industrial facilities, and energy management systems where automatic lighting control, occupancy-based switching, HVAC integration, and energy conservation are required. Its wide-area ultrasonic coverage makes it particularly suitable for spaces where occupants may remain relatively stationary or where line-of-sight detection is limited.
