The LiftMaster OES-COIL 2‑Wire Coil Cord is a flexible lead designed specifically for the LiftMaster Optical Edge System used on commercial and industrial door applications. It provides the moving connection between a monitored optical safety edge on the door bottom bar and the operator’s OES/monitored edge input, helping maintain continuous entrapment protection as required for modern monitored edge setups. As a direct replacement part for the Optical Edge System, this two-conductor coiled lead reduces strain and wire fatigue during door travel and is commonly used on rolling steel and sectional doors equipped with LiftMaster commercial operators that support a monitored edge circuit.
Installation involves connecting the cord to the designated Optical Edge System terminals at the operator and to the optical sensing edge assembly on the door, following the instructions provided with the operator and edge kit. After installation, the door’s entrapment protection should be tested per the operator manual and applicable safety standards. The OES-COIL is an ideal option when servicing or upgrading a monitored sensing edge on LiftMaster Logic-based commercial door operators, offering a clean, reliable connection for the OES optical edge hardware without the need for additional interface modules.
