Overview

The MOS-IR is a 360-degree ceiling-mount sensor that uses passiveinfrared (PIR) technology to detect occupancy. It uses wirelesstechnology to communicate with Echoflex controllers to efficientlymanage lighting and increase energy savings.

The sensor harvests solar energy from both natural and artificiallight sources. Its efficient energy management system eliminatesthe need for batteries in typical workplace settings. The MOS-IR issuitable for vacancy applications where energy codes require lightsto be manually turned ON and automatically shut OFF or dimmedwhen the space is vacant. Precision circuitry also allows it to provideimmediate response to new occupancy states, making it an idealsolution for partial-ON/auto-ON applications.

The MOS-IR incorporates test features that provide installers withthe ability to ensure sufficient energy harvesting, and occupancydetection without extra tools or software. Sensitivity settings for PIRcan be adjusted to eliminate false tripping and ensure the right levelof detection.

The sensor has three different lenses to provide suitable PIR coverage:lenses A and B are intended for office applications optimized forceiling heights of 2.4 to 2.7 m (8 to 9 ft). Lens C is intended forhigh bay applications, approximately 12 m (40 ft) ceiling height,and is equipped with a battery to guarantee consistent operation inlocations that have low light and are difficult to access.
