One of our garage doors was broken recently when it failed to automatically reverse after encountering an obstruction. The item that fell into the path of the door did not break the light beam near the floor, so the door didn't reverse but crushed it instead & in the process broke the door. I thought that garage door openers are required to have an auto-reverse safety device, but have been told that inclusion of such a device is voluntary. Most GDOs instead have the light beams that trigger a reversal. The problem is that there are numerous instances in which something or someone could be in the path of a closing door and not break the light beam (such as on a bicycle when the light beam passes between the wheels or in a car that's far enough in or out of the garage that the tires don't trip the sensor.)
We're lucky that the only damage was to the garage door and the item that fell into its path, and no people were hurt. Once we get the door replaced, I want to also replace our GDOs with ones that have both an auto-reverse feature and a battery backup. Can anyone suggest a reliable, quiet GDO that has both of these features? Thanks.
