  • Electronic security system
    Patent number: 5999095
    Abstract: An access control unit for an electrified door lock also toggles the state of an associated alarm. The unit is arranged to unlock the door only temporarily, but the alarm state is not toggled except by user request. The system is arranged to prevent the anomalous situation of an unlocked door and an armed alarm. Another aspect is the use of standardized key-receiving nests in disparate types of access control devices. Some disparate devices employ identical key-receiving nests, while others use different forms of nests. Yet all mate with and respond to a single type of key.
