The Sommer S10343-00001 Motion Detector is an original accessory for SOMMER garage door openers designed to automatically switch on the operator’s courtesy light when movement is detected in the garage. Ideal as a hands-free lighting upgrade or replacement part, this motion sensor helps illuminate the space as you enter, improving convenience and visibility without reaching for a wall switch or remote. It is intended for use with compatible SOMMER operators that support plug-in accessories, such as the pro+ and base+ series, and can also be used to trigger lighting add-ons like the SOMMER Lumi+, where supported. Typical applications include residential garages, workshops, and utility areas where automatic light activation is desirable.
Installation is straightforward: the module connects to the operator’s accessory interface and is configured through the opener per the manufacturer’s instructions. The detector is commonly used to control the built-in courtesy light on SOMMER openers and is designed for indoor, dry-location use within the garage. For safety, disconnect power to the operator before installing accessories and follow SOMMER’s installation and operating guidance for your specific model. If you are replacing an existing motion sensor, verify the part number S10343-00001 and check compatibility with your SOMMER base+ or pro+ control unit or any attached lighting module to ensure proper operation.
