LiftMaster 881LM 2-Pack Motion Detecting Control Panel with Timer-to-Close
The LiftMaster 881LM is a motion detecting wall control panel with Timer-to-Close functionality for compatible Security+ 2.0 garage door opener systems. This two-pack is useful when servicing more than one compatible opener or when keeping a matching spare control panel on hand for installations that use the same wall control family. The 881LM provides inside-garage opener control, automatic light activation when motion is detected, and timer-based closing functions when the connected opener supports those features.
This wall control is part of LiftMaster's Security+ 2.0 wall console family and should be matched to compatible yellow learn button openers. It is not a basic doorbell button and should not be treated as a universal wall station. The opener must support the communication and feature set required by the 881LM, especially for motion lighting and Timer-to-Close operation.

Technician Note
The 881LM depends on opener logic-board compatibility. A wall control that lights up does not always mean every feature is supported. If Timer-to-Close, motion lighting, lock, or programming features do not respond correctly, verify the opener model, safety sensor status, wall control wiring, and logic board generation.
Before Ordering, Confirm
- The opener is a compatible Security+ 2.0 model
- The opener has a yellow learn button when applicable
- The opener supports Timer-to-Close if that feature is needed
- The safety reversing sensors are installed and working
- The existing wall control wiring is intact and not shorted
- The replacement is not being used on an older basic dry-contact wall button system
Professional Advisory
Disconnect power before servicing wall control wiring. Timer-to-Close should only be used when required safety reversing sensors are installed, aligned, and functioning. Do not use a wall control upgrade to work around a failed safety system, damaged door, or opener with unsafe movement.
Questions & Answers
What opener systems use the 881LM wall control?
The 881LM is for compatible LiftMaster Security+ 2.0 garage door openers, commonly identified by a yellow learn button and the correct two-wire wall control connection.
What does Timer-to-Close do on the 881LM?
Timer-to-Close can close the garage door automatically after a selected time delay when the connected opener supports the feature and required safety systems are working.
Does the motion sensor open the garage door?
No. The motion sensor is used to turn on the opener lights when motion is detected in the garage. Door operation is controlled by the wall console button.
Can the 881LM replace a basic doorbell-style wall button?
Only on compatible Security+ 2.0 systems. Older openers that use a simple dry-contact wall button may not communicate properly with an 881LM control panel.
Is 881LM the same as 881LMW or 880LMW?
These are related LiftMaster wall control families, but they should be matched by opener model and feature requirements. Some current listings may use W-suffix or updated part numbers.
