Leviton offers three new dual relay multi-tech­nology wall-mount occupancy sensors that combine bi-level switching with passive infrared (PIR) and ultrasonic (US) technology. The new OSSMD, OSSMD-G, and OSSMD-F feature self-adaptive technology that compensates for realtime occupancy patterns. The OSSMD accommodates a range of application environ­ments and is compatible with incandescent, fluorescent, and low-voltage lighting, provid­ing automatic switching of two separate light­ing loads from a single unit. The OSSMD-G does not require a neutral wire for installation, making it suitable for retrofit applications. The OSSMD-F is designed for areas when there is a need for a delayed-off for the second relay. The line uses PIR sensing to detect motion, while US sensing provides maximum sensitivity and range. The sensors also feature walk-through sensing that automatically switches lights off after momentary occupancy. Additional features include an ambient light override feature to keep lights off when there is adequate natural lighting, adjustable field-of-view blinders, and a push but­ton for manual switching at any time.
