Optional password for unlocking and have a lot of time constraints, so there are very high safety factor. Circuit by the encoder password, the password storage control circuit input memory circuit, as the initial password. When you enter unlock password, the password stored in the control circuit first enter a password in order input to the corresponding memory chip. If the password and the default password unlock each lock signal corresponding to the circuit output and eliminate the alarm
