The LiftMaster 860LM Weather Resistant Receiver is an external, add-on radio receiver designed to bring reliable Security+ 2.0 remote control to gate operators, commercial door operators, and older or non-LiftMaster systems that need an upgraded radio interface. Housed for outdoor use, it’s built to handle exposed installations at gates, barrier arms, and industrial doors while delivering robust tri-band Security+ 2.0 performance for strong signal reception and reduced interference. The 860LM typically connects to an operator’s control inputs via a dry-contact relay and is powered by low-voltage supply (commonly 12–24V AC/DC), providing a simple retrofit path for residential or commercial applications, replacement projects, or range/radio upgrades where an integrated receiver is missing or incompatible.
Programming is straightforward using the receiver’s learn function to pair LiftMaster Security+ 2.0 transmitters and keyless entries, including popular remotes such as 811LM, 813LM, 891LM, 893LM, and compatible MAX series remotes set to Security+ 2.0. Operating on LiftMaster’s tri-band Security+ 2.0 technology (310/315/390 MHz), the 860LM offers enhanced signal reliability in crowded RF environments. For best results and safety, mount the unit in a suitable outdoor location per LiftMaster instructions, wire to the operator’s control terminals with power disconnected, and test entrapment protection devices to meet UL 325 requirements. This weather resistant receiver is an ideal choice for adding modern LiftMaster remote functionality to gates and doors in both residential and commercial installations.
