It’s not just a fancy warning sign.  

ProArmour is designed to secure classic auto-belays and prevent climbers from starting without clipping in.

ProArmour is an electronic safety system based on radar and touch sensors that detects when a climber isn’t attached to the auto-belay. If that’s the case, it automatically activates a set of red light indicators and a buzzer to alert both the climber and the gym staff.

ProArmour not only secures the route itself but also the boundaries on each sides.
