The Dual Tech Ceiling Mount Sensor (MOS-DT) is a 360 degree ceiling sensor providing reliable battery-free occupancy detection that communicates wirelessly with Echoflex controllers. A combination of passive infrared (PIR) and audio sensing technologies ensures positive occupant detection.The MOS-DT occupancy sensor is wireless and powered using solar energy harvesting from natural and artificial light sources. The advanced power management and efficient solar energy harvesting features make the optional battery redundant in normal workplace environments. Passive audio sensing technology provides coverage of audible human activity across much of the PIR detection range and innovative noise filtering is used to prevent false triggers that keep lights on in empty rooms. The MOS-DT fits well in energy code vacancy applications (manual-ON + automatic-OFF) while providing immediate response to new occupancy states making it an ideal solution for automatic-ON lighting applications.The MOS-DT incorporates test features that provides installers the ability to ensure reliable communications, sufficient energy harvesting and occupant detection without extra tools or software. PIR and audio sensitivity adjustments can be made to eliminate false tripping insuring reproducible operation.The MOS-DT is available in two models providing PIR ranges suitable for small or larger motion detection, optimized for ceiling heights of 8-9 feet.
