    Technical specifications for the Risco LuNAR Series ceiling mount motion detectors with 360° coverage — LuNAR DT (dual technology PIR+Microwave) and LuNAR PR (dual element PIR).

    Overview

    The LuNAR Series is ideal for areas where wall or corner mounting is unsuitable — for example, rooms where wall placement would be blocked by shelves, closets, or storage areas. LuNAR DT and PR can be installed up to 4 meters (13 ft) high. Both use a special 110° wide-angle spherical Fresnel lens providing full 360° coverage, in a slim, low-profile design suited to commercial and residential ceiling-mount applications.

    Model Highlights

    • LuNAR DT: Microprocessor-controlled dual technology (PIR + Microwave); patented true temperature compensation; proprietary detection algorithm; microwave range adjustment; superior fluorescent interference rejection; low profile design.
    • LuNAR PR: Dual element PIR technology; adjustable sensitivity with variable pulse count; superior fluorescent interference rejection; low profile design; cost-effective ceiling mount option.
