The present invention relates to a method 400 and a system 100 for controlling a robotic garden tool 202 around a working area 204 in a boundary wire aided system. The system includes the robotic garden tool 202 to perform an operation within the working area 204, which is at least partly defined by a boundary. The boundary separates the working area 204 from a non-working area. The robotic garden tool also includes detecting means for detecting the boundary. Further, the robotic garden tool 202 is adapted to receive a status signal 110 sent from a signal source and the robotic garden tool 202 is configured to stop the operation, when the status signal 110 provides a stopping signal.
