Abstract
A force reversal value for an installed barrier is identified. The force reversal value is compared to a predetermined threshold. When the comparing indicates that the force reversal value exceeds the predetermined threshold, the operation of the moveable barrier operator is halted. A secondary safety device can then be installed and, responsive to the installing, the operator can be reenabled.
