Liftmaster LWLOOP Monitored Wireless Edge Kit and Plug In Loop Detector
The LiftMaster LWLOOP is a combined accessory solution for gate systems that need monitored edge protection and loop-based vehicle detection. In a typical installation, the wireless edge portion helps transmit a monitored resistive edge signal back to the operator, while the plug-in loop detector monitors a properly installed ground loop for vehicle presence or movement commands.
This type of kit is commonly used on swing and slide gate systems where trenching or routing a hardwired edge cable is difficult, or where the installer wants a cleaner connection between the moving gate and the operator control board. It can also reduce wiring clutter because the loop detector plugs into compatible LiftMaster boards that are designed to accept the module.
Correct fitment matters. The gate operator must have the correct monitored safety inputs and loop detector socket, and the edge being used must be a compatible monitored resistive edge. This kit should not be treated as a universal wireless transmitter, universal receiver, or generic loop detector.
Compatible With
Common Compatible Applications
- Compatible LiftMaster gate operators with monitored safety input capability
- LiftMaster operators with the correct LOOPDETLM plug-in loop detector connection
- LiftMaster commercial slide gate and swing gate systems that accept monitored edge devices
- Applications using compatible LiftMaster monitored resistive edge families, commonly including L50 and S50 style monitored resistive edges
- Gate systems requiring monitored edge protection plus a plug-in loop detector for vehicle detection
Compatible Operator Families to Verify
- LiftMaster CSL24U and CSW24U family operators when equipped with the correct monitored safety and loop detector connections
- LiftMaster LA400PKGU and LA412PKGU style gate operator applications where the loop detector instructions and operator board support the accessory
- LiftMaster DC gate operators with UL 325 monitored safety inputs, when confirmed by the operator manual
- LiftMaster gate operators using plug-in loop detector functions for exit, shadow, or interrupt loops
Important Compatibility Notes
- Verify the operator control board has the proper plug-in detector port before ordering.
- Verify the edge is a monitored resistive edge, not a basic non-monitored contact edge unless the installation documentation specifically supports it.
- Confirm the loop function needed at the site before setup: exit, shadow, or interrupt.
- Do not use this product to bypass a monitored safety device requirement.

Technician Note
The most common mistake with this kit is assuming every LiftMaster gate operator accepts the same plug-in loop detector and wireless edge setup. Always check the control board layout and the operator manual before replacing parts.
Before Ordering Checklist
- Confirm the gate operator model and control board generation.
- Verify the operator has monitored safety inputs and the correct plug-in loop detector port.
- Confirm the safety edge is a compatible monitored resistive edge.
- Identify whether the loop is being used as exit, shadow, or interrupt.
- Inspect the existing edge, transmitter, receiver, and loop wiring for damage before replacing only one part.
Important Ordering Warnings
- Not a universal loop detector for every LiftMaster or non-LiftMaster gate operator.
- Not a substitute for required UL 325 monitored safety devices.
- Wireless edge range and performance depend on mounting location, obstruction, battery condition, and site interference.
Professional Advisory
Gate safety devices are part of the entrapment protection system. If the gate is moving unpredictably, has missing monitored devices, or has failed safety inputs, have the system inspected by a qualified gate technician before returning it to service.
Product Questions & Answers
What is included in the LiftMaster LWLOOP kit?
The LWLOOP combines LiftMaster monitored wireless edge hardware with a plug-in LOOPDETLM style loop detector for LiftMaster gate operators that support these accessories. It is commonly used when both edge monitoring and vehicle loop detection are needed on the same gate system.
Does LWLOOP work with any gate opener?
No. It is intended for compatible LiftMaster gate operators with monitored safety inputs and a plug-in loop detector port. The gate operator model, control board, and monitored safety requirements should be checked before ordering.
What type of edge is normally used with this kit?
The wireless edge transmitter side is used with compatible LiftMaster monitored resistive edge applications, including common L50 and S50 style monitored resistive edge families when the installation is configured correctly.
Can the plug-in detector be used for exit, shadow, or interrupt loops?
The compatible LiftMaster plug-in loop detector can be configured for common loop functions such as exit, shadow, or interrupt use when the operator supports that function and the loop is installed correctly.
Should this be used to bypass a required safety device?
No. Monitored safety devices must not be bypassed. If a gate has missing, failed, or incorrectly wired safety devices, the system should be inspected and corrected by a qualified gate technician.
