PROBLEM TO BE SOLVED: To prevent the occurrence of such a situation that an electric lock system does not operate normally because the unsetting of an equipment authentication code is caused, for example, by the omission of the setting of the equipment authentication code; and to inhibit an electric lock from being fraudulently opened by utilizing the illegally acquired equipment authentication code.SOLUTION: When receiving an unlocking command transmitted from a control panel 7, a control unit 3 authenticates the control panel 7 by using the equipment authentication code which is added to the unlocking command. In addition, when detecting an unlocking operation of the electric lock 2 and opening of a door 8, the control unit 3 generates an equipment authentication code different from the precedently generated equipment authentication code, makes the generated equipment authentication code stored in the memory 16 of the control section 3, and transmits the equipment authentication code to the control panel 7; and the control panel 7 stores the equipment authentication code, which is transmitted from the control unit 3, in a memory 32. Thereby, the equipment authentication code is automatically set only by making the electric lock 2 operate for unlocking and making the door 8 opened. Furthermore, the equipment authentication code is changed each time the door 8 is opened by making the electric lock 2 operate for unlocking. |
