PROBLEM TO BE SOLVED: To provide a notification controller capable of preventing wrong calling from being generated and capable of reducing a situation leading to a serious accident.SOLUTION: When a switch 10 is operated, an abnormal signal based on a detection signal and/or an abnormal signal received at an input/output 13 by switching means is switched so as not to be outputted. If the detection signal is not received by the input/output part 13 again after the detection signal is received by the input/output part 13, switch means is controlled and switched so that the abnormal signal based on the detection signal and/or the abnormal signal based on the detection signal received by the input/output part 13 are outputted.
