Liftmaster OES-SD24 Optical Edge System

Designed specifically to work with LiftMaster® Commercial Door Operators, the Optical Edge System delivers dependable monitored entrapment protection for commercial applications. The infrared optical sensors provide superior protection
for sectional and rolling-style doors. With a NEMA 6 enclosure, it is the ideal solution for commercial doors with edges exposed to outside elements. Our photoelectric eyes and edge sensor models are UL/cUL Listed for use with all LiftMaster Commercial Door Operators. The Optical Edge System can be used as a primary and/or ancillary entrapment device and meets UL 325 2010 safety standards.

- 24' Sectional Door Edge Kit.
- Rubber door edge is durable, flexible and easy to install.
- Premium rubber can be cut to exact length at the installation site.
- NEMA 6 rating protects against moisture and allows edge to operate in standing water.

- Maximum range of 33 feet.
- Meets UL 325 2010 safety standards.

UL 325 requires all commercial door operators to be either constant pressure to close or be equipped with a primary external monitored entrapment protection device. The Optical Edge System meets this requirement. Failure to use the appropriate sensor or failure to install the sensor properly, may expose the installer and customer to liability, should an accident occur.

Quick Install Guide

Be sure to disconnect power to the operator BEFORE installing the Edge Kit. The door MUST be in the fully opened or mid position before installing the LiftMaster® Monitored Entrapment Device.

Correctly install, connect and test the photoelectric edge sensors for proper operation. Install the photoelectric edge sensors on the closing or opening edge of the sectional or rolling door.

Follow instructions to complete the installation before powering-up the operator. Photoelectric door edge sensors must be at least 3 feet apart for alignment verification.
