The LiftMaster K002D2085 Dock Door Interface (LMi5) is a control module designed to integrate a loading dock’s overhead door with auxiliary dock equipment for safer, coordinated operation. Used in commercial and industrial applications, this interface helps interlock the door operator with devices such as vehicle restraints, dock levelers, and red/green dock lights so the door only moves under acceptable conditions and personnel receive clear visual status cues. It is a practical replacement part or upgrade for facilities looking to standardize dock door controls and streamline sequences like “restrain truck, signal green, enable door open.”
The LMi5 provides low-voltage control connections that tie compatible LiftMaster commercial door operators to common dock safety and productivity devices, enabling inhibit/permission logic and status signaling based on door and equipment states. Typical use involves wiring inputs from restraint or leveler status switches and routing outputs to dock traffic lights or operator control circuits to enforce safe operating sequences. Installation and setup should be performed by qualified technicians in accordance with the door operator’s manual and applicable safety standards, verifying all interlocks and indicators function as intended. For compatibility with specific LiftMaster commercial door operators and dock equipment, consult the manufacturer’s documentation before purchase or installation.
