Most new garage door operators include several safety devices to protect all users. In most basic systems currently sold there are at least two automatic safety systems to protect the public from being crushed by the closing door.

One basic function includes an automatic reverse of the door when in the opening or closing cycle. If the door encounters obstructive forces, it generally will stop and move in the opposite direction of travel. In the closing mode, the downward force is often checked by placing a small stuffed animal on the threshold floor of the garage. The motor controller has a field adjustable force control that is set to react when a soft obstruction, such as a teddy bear is slightly compressed. This simulates the potential obstruction that may be caused by a small child in the path of the downward door travel.

The second safety device, commonly in usage are photo electric beams. These beams when properly located and integrated across the full width of the garage threshold will not allow the door to close if the beam is broken by something in the threshold path of travel of the door.

From a professional installer’s perspective, there are numerous requirements that need to be addressed for an automatic operator to function safely.
