The LiftMaster 02103 3-Button Indoor Surface Mount Station (NEMA 1) is a hard‑wired wall control designed for commercial and industrial door operators. It provides dedicated OPEN, CLOSE, and STOP functions for safe, on-demand operation of sectional doors, rolling steel doors, and other commercial doors powered by LiftMaster operators. Intended for interior use, this surface-mount station is a reliable replacement part or add-on control for facilities like warehouses, service bays, loading docks, and maintenance areas, and is compatible with many LiftMaster commercial operators that accept a three-button, dry-contact wall station.
Built with a NEMA 1 enclosure for general-purpose indoor environments, the 02103 is labeled for clear, intuitive use and includes a prominent STOP control to quickly interrupt door movement. The station wires to the operator’s low-voltage control terminals; follow the specific operator manual for terminal assignments, wiring polarity (if applicable), and any interlock requirements. No programming is required—installation involves mounting the station and terminating the control leads per the LiftMaster operator’s instructions. For safety and code compliance, install within line-of-sight of the door, ensure entrapment protection devices are in place and functional, and follow UL 325 and local electrical codes. This 3-button wall station is commonly used with LiftMaster trolley, jackshaft, and hoist operators across Logic-series platforms in indoor commercial applications.
