Zusammenfassung:An example apparatus includes switches to be distributed along an interior of a guide for a door, the switches to switch between a first state and a second state, the switches in the first state to extend into a path of a door curtain of the door, the switches to be urged to the second state by the door curtain as the door curtain moves along the path. The example apparatus also includes a controller to identify when the door curtain transitions from an operational state to a breakaway state based on a signal from a first switch of the switches.
