ABSTRACT:
An electronic lock system is provided with an audible entry monitor for confirmation of entry of an input code and a mischief preventive circuit for disabling the audible entry monitor for a given period of time in response to an excessive number of inaccurate code input attempts. The audio signal generator is associated with a pushbutton input unit having a plurality of push buttons. The audio signal generator is adapted to produce an audible signal whenever an input code is entered through the input unit. The audible signal generator is also associated with a comparator for comparing the input code and a permanent code. The comparator is adapted to allow the system to change a voluntary code and operates the audible signal generator to produce another audible signal for a predetermined period while the system is capable of accepting entry of the new voluntary code to be preset.
