ABSTRACT:
An electronic access control system for controlling a lock in which the inputs and outputs are multiplexed, the electrically programmable read only memory is written to and read from in a serial manner, and the operator can disable access codes and enable access codes in one operation. The device reduces power consumption when powering a solenoid or DC motor by pulsing the output power. Further, the device is able to be operated in a remote location whereby the remote device can accept inputs from a keypad, an electronic signal, or a telephone line. The remote device, when not in active operation, operates in a low power mode so that the remote device may be powered by a battery.
