Liftmaster® 8550 DC Battery Backup belt drive


I have been posting off and on, even on other sites about this new technology. It has so many features, some we have set up in our showroom. Just a little more to show how Liftmaster® is making your home safer and more responsive to how you live. Here is a little more information on this great technology equipment.

Auto force and electronic limits means the garage door adapts to weather and changing environmental conditions, which means less maintenance for you.

Security + 2.0 technology is designed to communicate with the garage door opener in different frequencies.  This enhanced radio virtually eliminates interference and provides you with the highest level of security.

The Protector System® safely sensors project and invisible light beam across the garage door opening and automatically reverse the door if anything interrupts the beam while the door is going down.  Garage door opener lights turn on automatically when the Protector System infrared beam is broken.

Alert-2-close warning system provides UL325-compliant audible and visual warnings that the garage door is about to close when using the Timer-to-close, or remote closing features. (Timer-2-close is for sectional doors only, not one piece doors).

Patented Posilock® system ensures the door remains securely locked when it is closed.
