Abstract
When a start failure detecting circuit detects a start failure of an elevator cage, a signal transmitting and receiving device automatically dials a telephone number of a maintenance and service company to connect a telephone line thereto and at the same time transmits a recorded signal from a signal recording device to the maintenance and service company over the telephone line. The maintenance and service company decides how serious the start failure is on the basis of the transmitted recorded signal. When the start failure is determined as being less serious, the maintenance and service company transmits a restoration signal to the signal transmitting and receiving device. In response to the restoration signal, a reset circuit generates a reset signal to bring the control board back to the same condition as when the power supply is initially switched on, to thereby restore the disabled elevator.
