The LOS-C series ceiling mount sensors offer a wide range of technologies and can either integrate into Lutron systems (no power pack needed) or function as stand-alone controls using a Lutron power pack. The ultrasonic sensors have excellent minor motion detection, such as typing at a keyboard. The passive infrared sensors provide false tripping immunity, and are better suited for major motion. The dual-technology versions combine both features to provide optimal power savings and occupancy detection. The LOS-C sensors all have self-adaptive technology that eliminates the need for manual adjustments. After correct mounting, the sensors automatically adjust sensitivity and timing to prevent false-off and false-on conditions. To control other building systems such as HVAC or security system use the ‘R’ models, which provides an additional dry contact closure.
