3850
Strong and quiet, this DC-powered garage door opener provides maximum performance and the ultimate in quiet operation. The enhanced belt drive is the quietest system ever designed. It is perfect for homes with a family room/ bedroom located directly above the garage. The 3850 opens the garage door slowly . . . then speeds up . . . and comes slowly to a stop quietly and smoothly.
The model 3850 is loaded with exceptional features. The exclusive Smart Garage Door Opener lets you electronically program security codes, and is conveniently located for easier access. Two 100 watt light bulbs and a delay setting control of 1 1/2 minutes to 4 1/2 minutes allow for 33% more light and better control. Also, advanced electronics now allow you to open and close your garage door from greater distances.
In addition to outstanding features, all LiftMaster operators have numerous safety features to give you peace-of-mind. The Protector System projects an invisible light beam across the inside of the garage door opening by way of two photo eyes at the base of the door. If anything interrupts the beam while the door in going down, the door automatically reverses before making contact. If the beam is obstructed, the door will not close at all. The PosiLock system securely locks your garage door as soon as it goes down. An intruder cannot gain access. Also, a manual release handle releases the door from the operator for manual operation in the case of a power failure.
The 3850 comes with a lifetime motor and belt warranty.
Last (but certainly not least), the 3850 is available with the new EverCharge Battery Backup System - a system exclusive to this model. Now, you can rest assured knowing your family will have complete access to your home in the case of a power outage. The EverCharge battery backup system operates your LiftMaster garage door opener as if the power were still on, so you won't have to manually lift the door. It's not only a convenience, it's safer! The system is always charged and ready. After the power goes out, the barrery backup system will operate the garage door opener for 200 full cycles within a 24 hour period. It mounts quickly and easily on the opener or to the ceiling. No special tools are required. The EverCharge comes with a one-year warranty.
