Essential Info

The Hubbell Bryant MSU2000C Ultrasonic Occupancy Sensor is excellent in detecting minor motion near the sensor. This sensor also includes Bryant’s Adaptive Technology which allows you to install and forget, saving time and money from not having to do constant adjustments. This technology also helps eliminate false-offs and disturbances. The digital, crystal controlled ultrasonic transmitter and receiver offers coverage in each direction for superior motion sensing. The ceiling mounted sensor is concealed in an off-white ABS enclosure that blends in with ceiling tile.

Ultrasonic (US) technology senses occupancy by bouncing sound waves (32 kHz - 45 kHz) off of objects and detecting a frequency shift between the emitted and reflected sound waves. Movement by a person or object within a space causes a shift in frequency, which the sensor interprets as occupancy. While US occupancy sensors have a limited range, they are excellent at detecting even minor motion such as typing and filing, and they do not require an unobstructed line-of-sight. This makes US technology sensors ideal for an application like an office with cubicles or a restroom with stalls.

The Bryant 360°, 2,000 Square Foot Occupancy Sensor is also available with 180°, 1,000 Sq Ft and 180°, 500 Sq Ft coverage, each sold separately.

    Adaptive Technology
    Adaptive Technology is a BRYANT exclusive and delivers benefits to both building owners and occupants. The building owner achieves reduced energy costs, fewer adjustments and less maintenance, and the building occupant experiences fewer false-offs and disturbances. Adaptive technology occupancy sensors use microprocessors that make all the decisions for setting adjustments. Internal software constantly monitors the controlled area and automatically adjusts the sensitivity and timer based on environmental history. Instead of manually adjusting the sensor for seasonal changes, modified airflow, furniture layout or occupancy pattern changes, the sensor automatically adjusts itself. These automatic adjustments eliminate the need for multiple manual adjustments by maintenance personnel or outside contractors. BRYANT offers adaptive technology throughout its product offering - wall switches, ceiling and wall mount sensors in conjunction with dual technology, ultrasonic and passive infrared products.
