LiftMaster 850LM Universal Gate & Garage Door Receiver | 3-Channel Security+

Overview

The LiftMaster 850LM Universal Gate and Garage Door Receiver is a compact, versatile solution designed for busy gate entrances and commercial sites. Built with Security+ 2.0 technology, it leverages a narrow band multi-frequency radio to minimize interference and support reliable control from a vehicle. This receiver is designed to integrate with existing remotes, making it a flexible backbone for a unified access system.

Key capabilities

Designed to work with 811LM, 813LM, and all MAX remotes, the 850LM provides a single point of control that scales across properties. It expands to three channels, so you can tailor access for different user groups:

• Channel 1: up to 50 remotes
• Channel 2: up to 20 remotes
• Channel 3: up to 20 remotes

The unit's compact design fits most gate operators and commercial door operators, enabling installation in tighter spaces without sacrificing performance. With a single transmitter, you can grant access for gated communities, industrial facilities, and commercial sites, keeping operations streamlined across multiple entry points.

Smart options and daily use

• Multiple remote control options provide secure vehicle access at entry points
• Security+ 2.0 technology and the narrow band radio aim to reduce interference and range-related call backs
• One transmitter solution simplifies management across diverse access points

In real-world use, a driver may arrive at a community gate on a busy morning, relying on a single remote to open the gate and, if needed, another channel to reach a service door. For facility managers, the 850LM can support a fleet of remotes for gates, barriers, and doors, reducing the need for multiple devices.

Overall, the LiftMaster 850LM receiver is designed to offer practical, scalable access control that fits into existing infrastructure. The emphasis is on ease of installation, dependable performance, and a single transmitter approach that can adapt to changing access needs over time.
