Abstract
A door security system for a door having an electrically actuated lock. The lock is controlled by a lock controller having an audit trail memory. An entry code reader transmits entered access codes to the controller. The controller compares the entered access code to prestored access codes and actuates the lock in response to the comparison. The controller stores the entered access code and a time stamp in the audit trail memory.
