INTRODUCTION
The LiftMaster Wireless Edge Kit provides a Bluetooth
resistive edge (not included) and the gate operator. Maximum range is 130 ft. (39.6 m.) (for best
results install with a clear line of sight between transmitter and receiver, objects in the path may
reduce range). You can program up to 4 transmitters to the receiver. The kit works with LiftMaster
monitored resistive edge sensors ONLY. Contact closure edge sensors are NOT supported.
Refer to your gate operator manual to ensure compatibility (LMWEKITU and LMWETXU is listed
under Monitored Entrapment Protection devices of the Accessories section). Transmitter and
receiver are UL Recognized Components and meet UL 325 requirements. A monitored entrapment
protection device MUST be installed in each entrapment zone.
