PROBLEM TO BE SOLVED: To enhance security by reducing opportunities of leakage of an equipment authentication code to the outside so as to inhibit unauthorized unlocking.SOLUTION: When an electric lock 2 is operated for unlocking by transmitting an unlocking command to a control unit 3 from a control panel 7, the control panel 7 adds the equipment authentication code of the control unit 3 to the unlocking command, and transmits it to the control unit 3. The control unit 3 performs collation processing associated with the equipment authentication code added to the unlocking command, and makes the electric lock 2 operated for unlocking, only when the equipment authentication code is an authentic one. When a command except the unlocking command is transmitted in communication between the control panel 7 and the control unit 3, the equipment authentication code is not added to the command. Thereby, the opportunities, in which the equipment authentication code is acquired by equipment except equipment constituting the electric lock system 1, are reduced for the inhibition of the leakage of the equipment authentication code to the outside. |
