The LiftMaster OES-SDKIT Optical Edge Component Kit (Sectional) is a monitored optical sensing edge solution designed for the bottom of sectional overhead doors. As an entrapment protection device, it helps stop or reverse the door when the edge is deflected during closing, enhancing safety in commercial and industrial applications. This kit is intended for new installations or as a replacement part/upgrade on systems that require a monitored safety edge and is engineered to work with compatible LiftMaster commercial door operators that support an OES (Optical Edge System) input.
When properly installed on the door’s bottom bar and connected to the operator through a suitable coil cord or take-up reel (sold separately), the OES-SDKIT provides a monitored safety signal that the operator can supervise for faults. Setup typically involves mounting the optical edge components to the bottom of the sectional door, routing the cable to the operator, and programming the operator to recognize the monitored edge type per the operator’s manual. Use only on sectional doors; different kits are used for rolling steel doors. For compliance and safety, follow LiftMaster installation instructions and perform functional safety tests after wiring and programming to verify stop/reversal response during door closing.
