Abstract
A warning system for use with a climbing wall and an automatic belay apparatus for belaying a climber, the warning system providing a warning that a climber is not protected by the auto-belay apparatus. The warning system includes a sensor positioned to sense that a lower end of the climbing rope is secured to the climbing wall and the climber is not attached to the auto-belay system which indicates a dangerous situation, and a height sensor for sensing when the climber has reached a selected height on the climbing wall. A processor receives signals from the sensors and compares the signals to determine if the climber has reached the selected height with the lower end of the climbing wall still secured to the wall, and if so, then actuates a warning alarm.
