摘要: A safety system (100) for controlling the activation of one or more downhole tools (112) by providing selective transmission an signal energy stream. The stream is allowed after tool has passed below a known pre-determined depth. includes first device (100A) in fixed relationship with and second (100B) stationary location. permits, reaching depth, initiation to reach (114) associated (112). positively engages provide indication that specified depth been reached.
