The Liftmaster 883LM Door Control Button serves as a vital Replacement Component for modern garage door systems, providing a streamlined and reliable interface for manual operation. As an OEM Gate Part, this lighted push-button is engineered specifically for systems utilizing Security+ 2.0® technology, ensuring seamless integration with your existing Access Control infrastructure.
Designed for both residential utility and light commercial applications, the Liftmaster 883LM offers a compact footprint without sacrificing durability. This control button allows users to open and close their garage doors from a fixed internal location, acting as a secure secondary or primary access point. Its backlit design ensures high visibility in low-light environments, such as unlit garages or corridors, providing an added layer of safety and convenience for the end-user.
Key Features & Benefits
• Security+ 2.0® Technology: Encrypts the signal sent to the opener to virtually eliminate interference and prevent signal hacking, ensuring the highest level of property security.
• Illuminated Push Button: Features an internal LED that provides a soft glow; this ensures the control is easily located in total darkness for immediate operation.
• Compact High-Impact Housing: Constructed from specialized polymers to resist wear and environmental stress, ensuring long-term reliability in non-climate-controlled environments.
• Two-Wire Easy Install: Utilizes a standard bell wire connection, which simplifies the retrofitting process for professional installers and reduces labor time on-site.
• Momentary Contact Operation: Provides a crisp, tactile response upon pressing, giving the user immediate feedback that the command has been registered by the logic board.

Frequently Asked Questions
Q1: Can I use the 883LM with an older LiftMaster opener if I change the wiring?
A1: No. The 883LM is not a standard "dry contact" button. It communicates via a proprietary serial encrypted signal used by Security+ 2.0® systems. It will only function with openers that have a Yellow Learn Button.
Q2: Does the polarity of the wires matter during installation?
A2: Yes. For the LED to illuminate and the button to function correctly, the wires must be connected to the correct terminals on the opener (typically the Red and White terminals). If the button does not light up after installation, try reversing the wire leads.
Q3: Can I install multiple 883LM buttons to one opener?
A3: Yes, multiple 883LM buttons can be wired in parallel to the same opener terminals, allowing for door control from various points within the garage or facility.
Q4: My button is glowing, but the door won't move. What is the issue?
A4: If the LED is lit, the unit is receiving power. Ensure the opener is not in "Lock Mode" via a primary multi-function control panel. If Lock Mode is off, inspect the wiring for staples that may have pierced the insulation, causing a signal short.
Q5: Is this button weather-resistant for outdoor mounting?
A5: The 883LM is designed for interior use or protected environments. For exterior gate applications, we recommend housing the component in a NEMA-rated weatherproof enclosure or using a dedicated outdoor-rated keyed switch or keypad.
