SECURITY STRUCTURE UNLOCKING SYSTEM FOR USE BY EMERGENCY RESPONSE AND AUTHORIZED PERSONNEL

摘要

A security structure-opening assembly and method for providing a security structure-opening system (12) for use in unlocking a locked structure (24) comprising: a radio frequency receiver (16) formed to detect radio frequency signals on a radio frequency; an actuator (20) coupled to the receiver (16) and formed for coupling to one of a security structure lock assembly (25) and an unlocking mechanism (22A) for a security structure lock assembly (25) at a position by-passing any authorized user input device (23); the receiver (16) being responsive to detected signals to actuate the actuator (20) and produce unlocking of the lock assembly (25). At progressively higher levels of security, the radio signal is analyzed by a private line detector circuit (30), a digital burst detector circuit (31) and a decoder circuit (32).
