ABSTRACT:
In order to determine the position of a device newly introduced into a hazard detection system, the devices of which include an insulator and are connected to a control center by a warning line, the newly introduced device is interrogated multiple times from one side of the warning line. The insulator of a device with an already known topology is first opened, subdividing the warning line into two branches, and the branch wherein the newly introduced device is located is then determined. This interval halving process is repeated until the exact position of the newly introduced device is found. In its preferred implementation, the device is a hazard detector or an actuator.
