摘要：
A movable barrier apparatus, a kit configured to be assembled and mounted adjacent to a barrier opening, and a method of monitoring for ballooning of a movable barrier are described herein. A sensing device is positioned outwardly from a drum configured to receive a movable barrier therearound. A ballooning movable barrier engages or disturbs the sensing device, which, in response to the disturbance, sends a signal, such as a signal to sound an alarm, stop movement of the door, or the like.
