Abstract
A security system includes a microcomputer with an auxiliary read-only memory and a key device including a similar read-only memory, each of the read-only memories containing corresponding pluralities of corresponding binary combination codes. Under the control of the microcomputer the codes are read and compared. If the combinations and the sequence do not compare, the system will not unlock and an alarm will be generated. The read-only memories are of the programmable type, so that changes in the combinations and sequences can be accomplished easily. A plurality of visual indicators and an audible alarm provide the user and personnel in the secure area with information concerning the status of the system.
