LiftMaster LMWETXU Monitored Wireless Edge Transmitter — Supports Two Resistive Edges

The LiftMaster LMWETXU is a monitored wireless edge transmitter for compatible LiftMaster gate-safety systems. It connects up to two compatible wired resistive edges to a wireless edge receiver, reducing the need to route a moving-gate cable back to the operator. This is the transmitter component, not the complete LMWEKITU receiver-and-transmitter kit and not a safety edge by itself. Select it when adding or replacing a transmitter in an approved monitored edge installation.

Compatibility — Models, Versions and Exclusions

Transmitter, Receiver and Edge Are Different Components

The edge senses physical contact, the transmitter communicates that condition, and the receiver passes the monitored information into the approved operator system. A transmitter-only purchase is useful when the receiver is already installed and compatible, but it does not make an unprotected gate safe on its own. Identify every component before deciding which item needs replacement.

The advertised range is a maximum, not a guaranteed distance through metal structures or other obstructions. Evaluate the mounting position and communication path at the installation. If a system has intermittent faults, check the edge, wiring, battery condition and receiver connection before assuming a replacement transmitter will resolve the problem.

Specifications and Product Identification

Before Ordering

• Record the operator model, receiver model and existing transmitter count.
• Identify the exact edge models, their positions and the direction of protection required.
• Plan a protected mounting location and a suitable communication path.
• Check battery condition and any reported monitored-system fault before ordering replacement electronics.

Package Contents and Separate Requirements

This SKU identifies the transmitter. A receiver and the resistive edge sensors are separate system components. Confirm the current transmitter carton for batteries and mounting hardware; the complete LMWEKITU kit inventory should not be copied into a transmitter-only order.

Safety Warnings — Read Before Installation or Service

• WARNING: A failed or incorrectly connected safety edge can leave a crushing or entrapment hazard. Installation and testing require a trained gate-systems technician.
• Isolate operator power before wiring and keep the moving gate clear of people during setup.
• Never bypass a monitored input or conceal a fault to restore automatic movement. Correct the fault before normal service.
• Use the specified replacement batteries and test every connected edge, its assigned direction and the monitored response after service.

Related Products and Important Differences

• LMWEKITU monitored wireless edge kit — choose the complete-system offer when the receiver is also needed.
• S504AL 4-foot monitored edge — a separate contact-sensing component; confirm that its length covers the required zone.
• LMRRUL monitored photo eye — a different, non-contact protection method; it does not replace the transmitter’s edge-sensing function.

Frequently Asked Questions

Is LMWETXU the same as LMWEKITU?

No. LMWETXU is the transmitter; LMWEKITU is the complete wireless edge kit. Check whether your installation already has the compatible receiver.

Does Bluetooth mean smartphone control?

No. This connection carries safety-edge information to the receiver. It does not provide a phone-based gate-opening feature.

Can one transmitter handle two edges?

LiftMaster specifies up to two compatible wired resistive edges. The exact connection and direction configuration must follow the applicable instructions.

Will adding this eliminate all gate safety faults?

No. Edge condition, wiring, batteries, receiver communication and operator configuration all need to be checked.
