The invention further relates to a room access arrangement (13) having two revolving doors (1a, 1b).

An access control device includes a primary access barrier configured move between a closed position and an open position. The primary access barrier may be configured to extend into an access passage of the access control device to prevent access through the access passage when in the closed position and to move away from the access passage to permit access through the access passage when in an open position. An entry access barrier is positionable in the access passage of the access control device on a first side of the primary access barrier, and an exit barrier is positionable in the access passage of the access control device on a second side of the primary access barrier opposite the first side. Systems and methods relate to access control devices.

A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when actuated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A lever-locking mechanism or a twist-lock mechanism secures the device in place against or within a door frame and against the door.

A building security assembly includes a vestibule that may be attached to an entrance of an institution and the vestibule has an entrance and an exit. A first door is hingedly coupled to the vestibule to open and close the entrance. A second door is hingedly coupled to the vestibule to open and close the exit. A metal detection array is positioned within the vestibule to detect metal components of a firearm. A security unit is coupled to the vestibule and is in electrical communication with the metal detection array. The security unit locks each of the first and second doors when the metal detection array detects the metal components of the firearm to inhibit the individual from bringing the firearm into the institution.

A one-way passage system (1) comprises an entrance door arrangement (2a) and offset therefrom an exit door arrangement (2b). First and second side wall arrangements (3a, 3b) are provided therebetween, thereby defining a passage area (4). A sensor device (5) can detect persons (10): a) before the entrance door arrangement (2a); b) in the passage area (4) and/or after the exit door arrangement (2b).
A control device is configured to enter a safety operating mode and to close the entrance door arrangement (2a) when an analysis of sensor data indicates that a person (10): a) in the passage area (4) goes back in the direction of the entrance door arrangement (2a); and/or b) goes back after the exit door arrangement (2b) in the direction of the passage area (4).
An illumination device (20), which is arranged in the passage area (4) can illuminate the passage area in different colors. The control device can enter different operating modes, wherein the entrance door arrangement (2a) and the exit door arrangement (2b) are controlled accordingly depending on the operating mode, and wherein the illumination device (20) illuminates the passage area (4) with different colors depending on the operating mode.

A method, device and system for controlling opening of A-B doors are disclosed, which are applicable to a host of a system with A-B doors, the system with A-B doors comprising a first access control for controlling entry through the door A, a second access control for controlling entry through the door B and an electronic authorization conversion device. The method comprises: receiving a first verification request for an object to be verified sent by the first access control (S201); determining whether the object to be verified has authorization to pass through the door A (S202); if it does, sending an opening command for opening the door A to the first access control (S203); receiving, after the door A has been opened, an electronic authorization conversion request for the object to be verified sent by the electronic authorization conversion device, converting the authorization of the object to be verified to authorization to pass through the door B, determining a first validity time period for passing through the door B, and storing the first validity time period (S204); receiving a second verification request for the object to be verified sent by the second access control (S205); retrieving the stored first validity time period (S206); determining whether the door B can be opened (S207); if it does, sending an opening command for opening the door B to the second access control (S208), thus improving the security of A-B doors.
