All LiftMaster Openers and Operators should be purchased through a Dealer and professionally installed. MyQ® Technology enables you to securely monitor and control your facility operator and lights with your smartphone, tablet or computer for greater peace of mind. Alerts can be received as email or pop-up (push) notifications on a mobile device, ensuring the status of your commercial door.

MyQ Mobile App is a free download with no annual activation fee. Requires 828LM MyQ Internet Gateway to connect to MyQ Smartphone App. Dual Voltage Connections increase flexibility by enabling the installer to select the required voltage within phase, to meet job-site requirements. Single-Phase: 115V and 230V, 3-Phase: 208V, 230V and 460V, 575V is a discrete model without field-selectable voltage. Control Function Selector Dial enables easy selection and programming of (7) wiring types, from constant pressure to close, to specialized Timer-to-Close functionality to meet end-user needs. Continuous-Duty High-Starting Torque Motor performs in demanding industrial overhead door applications. Motor Removable without Affecting Limit Switch Settings saves time and money for maintenance. Adjustable Friction Clutch helps to protect door and operator from damage should the door meet an obstruction. Mid-Stop enables partial opening of door to a preprogrammed position for energy savings, time savings and convenience.

Maximum Run Timer reverses or stops door if closing time exceeds expected time-frame to limit damage to door and operator. Delay-On-Reverse Circuit prevents abrupt reversal of door, reducing wear on the door and operator system. 3-Button Control Station with Maintenance Alert System (MAS) provides open/close/stop functions and notification when routine maintenance is required.
