The model LiftMaster 8550W door operator is manufactured by Chamberlain Group. Its most important feature: it will operate the garage door for 20 cycles within a 24-hour period, and recharges automatically when the power comes back on. An audible signal tells you when the power is out and the EverCharge® Standby Power System is in use. Meets all UL325 requirements.
This opener includes the MyQ® Technology, now equipped with Wi-Fi, that allows to monitor, open and close your garage door from your smartphone, your tablet or your computer, and that from anywhere in the world.
