Herein disclosed is a safety lock system which includes an electric lock mounted on a gateway to a certain region, a card reader, a display device and a main controller. The main controller is arranged so that it can check the card data read by the card reader. Accordingly, when the card data are in agreement with the predetermined data, the main controller feeds a locking or unlocking drive signal to the electric lock. On the contrary, when the card data are not in agreement with the predetermined data, the main controller emits a first alarm signal to the display device. Furthermore, when the main controller receives a normal operation signal from the electric lock, the main controller emits a signal of confirmation of the normal operation of the electric lock to the display device; whereas when the main controller does not receive the normal operation signal, it emits a second alarm signal to the display device. |
