What does "Down System" mean?

The term "Down System" refers to the action of beginning to let rope down in a rescue scenario. This action is crucial in situations where a rescuer is lowering either a victim or equipment into a safer area below. In a rope rescue context, communications among team members are vital, and a "Down System" signal indicates that the lowering process is set to begin. This involves careful management of the rope and attention to any safety protocols in place, ensuring that the load is descended smoothly and securely.

The other options refer to different aspects of rope rescue operations. Stopping all movement is not aligned with the purpose of a "Down System." Similarly, asking if the main line is ready or confirming that the belay is ready are more checks or statuses rather than actions taken when initiating a downward movement. Each of those is important for ensuring safety and readiness, but they do not define the specific action of starting to lower a load, which is the central focus of the "Down System."
