LiftMaster 3840 ¾ HP Drive Garage Door Opener boasts of a powerful battery backup that allows the opener to complete as many as 40 cycles in 24 hours in case of a power outage. Here we have highlighted some of other notable features of LiftMaster 3840:

  • The protector system - Its USP is its invisible light beam. The door reverses automatically when the beam experiences any interruption while the door is going down.
  • Sensor Technology - It immediately deters the door from closing when it comes in contact with a person or object.
  • Opener Light - It turns on automatically when the infrared beam of the Protector System is broken.
  • Security with Rolling Code Technology - It generates a new code each time you use the Clickers control.
  • Manual Release Handle - It comes into effect in case of a power failure.
  • Patented PosiLock System - It helps ensure that the door remains locked when the garage door is shut.
