The LiftMaster 02-401M3 is a hardwired control panel designed to operate up to three commercial doors or operators from a single, outdoor-rated station. Built around a prominent mushroom-style STOP control for quick access, it provides straightforward OPEN/CLOSE/STOP functionality for demanding industrial and commercial environments such as warehouses, loading docks, and parking facilities. As a replacement or upgrade control station, it is intended for use with LiftMaster commercial door and gate operators that accept standard 3-button control inputs, and it may be used with many other brands that support compatible hardwired controls when properly connected per the operator’s wiring diagram.
This outdoor surface-mount station carries an NEMA 4/12 enclosure rating (N4/12), offering protection against weather, splashing water, dust, and oil for reliable operation in harsh locations. The layout supports three-door control while maintaining clear, tactile operator feedback for everyday use and emergency stop situations. Installation requires hardwiring to the operator control terminals by a qualified technician in accordance with local codes and the equipment manuals; always verify compatibility with the specific operator model and test all entrapment protection devices after wiring. This LiftMaster 02-401M3 mushroom button control panel is a practical, durable choice for universal commercial/industrial applications where simple, hardwired OPEN/CLOSE/STOP control and an easily accessible emergency STOP are required.
