ABSTRACT:
A controllable catch mechanism is installed in the door frame of hotel room to engage both a spring-biased latch and a deadbolt associated with the room door. The position of the deadbolt is sensed or a requirement for privacy is otherwise indicated with a switch within the room. An alphanumeric keyboard external to the room allows entry of access codes. If an authorized guest code is entered, a microprocessor-based controller unlocks the catch mechanism regardless of the privacy requirement. The guest code can be changed by the guest, as desired. If a cleaner enters a universal access code, the controller unlocks the catch mechanism only if the bolt is unlocked or no privacy requirement is indicated. Special override codes are provided that unlock the catch mechanism regardless whether the bolt is locked, permitting security staff to handle emergencies. A panic switch within the room causes an alarm signal to be generated and simultaneously releases the catch mechanism to allow security staff or passers-by to intervene. The operation of an HVAC unit and other equipment such as a telephone and television set are controlled in response to access codes.
