A linear gate operator from LiftMaster will work in a variety of applications, including residential, rural and solar. The LA400’s motor operates gates up to 15 feet wide and weighing up to 550 lbs. An alarm-reset button on the outside of the control box resets the alarm in a double-entrapment without having to remove the cover. The unit includes an on-board Chamberlain Security radio receiver with an external antenna, an external alarm reset button and an extended wiring kit. The radio receiver is compatible with all LiftMaster garage door openers. The unit can be mounted to round or square posts, steel or wood, and uses welded or bolted mounting hardware. Color-coded circuit board connections ease wiring. Buttons on the control panel set limits. The solar panel kit is available for installations where the power source is not located near the gate. A manual release replaces the usual pin to pull, and a battery backup system will keep the unit functioning up to 100 cycles in the event of a power outage. In addition, it has input/output terminals for accessories, including loops and photo eyes. It is available in single or dual gate operator packages.
