The LiftMaster 02703 Control Station is a 3-button Open/Close/Stop station engineered for classified locations requiring a NEMA 7/9 hazardous location enclosure. Designed for commercial and industrial door operator control in environments where flammable gases, vapors, or combustible dusts may be present, this explosion-proof station provides dependable operation of LiftMaster trolley, jackshaft, and hoist-style operators for rolling steel, sectional, and other commercial doors. Its clearly labeled, tactile push buttons support routine operation and emergency stopping, helping crews safely actuate doors from a convenient local position.
Intended as a replacement part or upgrade for facilities with hazardous area requirements, the 02703 is wired to the operator’s control circuit to issue momentary Open and Close commands and a positive Stop command, mirroring the standard 3-button control scheme used across many LiftMaster commercial operators. The NEMA 7/9-rated enclosure is built to contain internal ignition sources and is suited to properly classified installations when installed per NEC/NFPA and local codes. Typical use cases include petroleum and chemical processing, grain and food handling, wastewater treatment, and other areas where a hazardous location control station is required. For best results and compliance, have a qualified technician verify compatibility with the specific LiftMaster operator, match the location’s classification to the NEMA 7/9 rating, use appropriately rated conduit and fittings, and complete all wiring and interlocks per the operator manual and applicable codes.
