  • Patent number: 12499749
    Abstract: Security systems and methods thereof perform false alarm detection and diagnostics. A management station identifies at least one instance of an alarm at an access-controlled door within a predetermined time period. The management station also determines the possible root cause based on the two or more instances occurring within the predetermined time period. Each instance includes an alarm pattern including a door ok signal received from the door contact sensors and a door forced signal received from the door contact sensors subsequent to receiving the door ok signal. The door ok signal is associated with alignment of door contact sensors. The door forced signal is associated with misalignment of the door contact sensors. The door ok signal and the door forced signal correspond to the same instance. A remote device receives from the management station a notification distinguishing the possible root cause from a security hazard.
