Product Description
ETC MOS-DT-UB Dual-Tech Occupancy Sensor, Large Room (1900sq.ft.)
Overview
The MOS-DT is a 360-degree ceiling-mount sensor that detects occupancy and communicates wirelessly with Echoflex lighting controllers. A combination of passive infrared (PIR) and audio sensing technologies ensures positive occupant detection.
The sensor harvests solar energy from both natural and artificial light sources. Its efficient energy management system eliminates the need for batteries in typical workplace settings. Passive audio sensing technology provides coverage of audible human activity across the PIR detection range and innovative noise filtering prevents false triggers that keep lights on in empty rooms. The MOS-DT is suitable for vacancy applications where energy codes require lights to be manually turned ON and automatically shut OFF when the space is vacant. Precision circuitry also allows it to provide immediate response to new occupancy states, making it an ideal solution for auto-ON applications.
The MOS-DT incorporates test features that provides installers the ability to ensure reliable communications, sufficient energy harvesting, and occupancy detection without extra tools or software. Sensitivity settings for PIR and audio can be adjusted to eliminate false tripping and ensure the right level of detection.
The sensor has two different lenses to provide suitable PIR coverage: lenses A and B are intended for office applications optimized for ceiling heights of 2.4 to 2.7 m (8 to 9 ft).
