<p>PROBLEM TO BE SOLVED: To safely confirm operation of a preliminary tremor sensing device by fitting a detachable exciting device to the case of an earthquake sensing device provided on the lower part of the elevator passage for an elevator and detecting the preliminary tremor of earthquake, and enabling start and stop of the exciting device to be remote-controlled. SOLUTION: When earthquake control operation is confirmed, at first an operator A fits an exciting device 5 to the upper part of the case of a preliminary tremor sensing device 4, and after connecting a receiver 6B to a pit receptacle, gets into a car 1. The operator runs an elevator at ordinary operation, and pushes the in-switch of a transmitter 6A during running of the car 1 to output a radio signal 6a. The receiver 6B inputting the radio signal 6a oscillates the exciting device 5. When the oscillation is transmitted to the case of the sensing device 4, the indication signal of earthquake control operation is output from the sensing device 4 to a control circuit. Then the operator A confirms that the car is stopped at the nearest floor, and completes inspection of the operation of the sensing device 4 and the acting state of control operation.</p> |
