PROBLEM TO BE SOLVED: To provide a wire tension detecting type warning system easy to install. SOLUTION: A warning sensor 10 wherein a wire tension adjusting part 210 and a wire tension detecting part 220 are stored in one casing 201 is used. Thereby, if a worker moves only in one direction when installing it, connecting a wire to the warning sensor 10 and adjusting the wire tension can be carried out one by one. Or, a security sensor wherein a permanent magnet is disposed adjacently to a lead switch 225 is used, and it is structured so that a loading part loaded with the lead switch 225 is displaced, and the permanent magnet is not displaced. Thereby, fixing the wire 16 and electrically connecting it to the lead switch 225 can be simultaneously carried out. COPYRIGHT: (C)2004,JPO
