Description
The LiftMaster RSL12UL is a residential and light commercial slide gate operator engineered for properties requiring reliable performance, battery backup operation, and advanced access control functionality. Designed for residential communities, private properties, farms, ranches, and light commercial applications, the RSL12UL combines solar-ready flexibility, monitored safety devices, and smart connectivity for dependable perimeter access.
Powered by a reliable 12VDC system with integrated battery backup capability, the RSL12UL delivers smooth gate operation with soft start/stop functionality and mid-travel reversal to help reduce mechanical wear and extend operator life. Integrated myQ® technology enables remote monitoring and control, while Security+ 2.0® encrypted communication helps protect against unauthorized access. Wireless dual-gate communication simplifies dual-operator installations by eliminating the need for costly driveway trenching.
The operator includes monitored entrapment protection devices and is UL® Listed for Class I, II, III, and IV applications. PosiLock® technology helps prevent unauthorized manual gate opening, while Fire Department Compliance functionality allows the gate to automatically open during AC power loss or battery depletion when required.
