Abstract: A door closer may utilize a door closing device (e.g., spring) and a force adjustment device (e.g., a motor) in order to allow for manual door opening and assisted door closing. During operation, as a door is manually opened, the spring is loaded (e.g., compressed or tensioned) above its pre-loaded closed position state. Once manual opening is completed, the spring that is loaded during opening begins returning to the pre-loaded closed position state, and thus, moves the door automatically towards the closed position. Depending on the pre-loaded spring setting, the closing force of the door may not be enough to close the door, or to close the door with the preferred force. As such, during closing a controller may engage a motor not to drive the door directly, but to increase the pre-load of spring to increase the closing force in order to allow the door to close as preferred.

Abstract: A dampener for an exit device may be disposed between a portion of an exit device actuator and an exit device chassis so that the dampener dampens vibrations to reduce noise of the exit device and/or inhibit unintentional movement of the actuator to an actuated position. The dampener may be composed at least partially of a viscoelastic material.

Abstract: A detection sensor or a user device is used to aid in providing authentication and activation of a door system when a user tries to access the door for ingress and egress. Operating parameters of the door systems may be set to allow ingress and egress only when a user is identified and authorized. As such, the operating parameters of the door systems may include authentication and activation parameters such that the door systems are controlled, at least in part, based on the presence of a user and/or a user device and the identification of the specific user. As such operating parameters may be different for different users or types of users. Moreover, the user device may be used to authenticate a user and control ingress and egress through the door automatically or through an authentication action taken by the user.

Abstract: During operation of the door system one or more sensors may be utilized in order to monitor the operation of the door assembly (e.g., door system, door, frame, etc.), review the operating parameters, troubleshoot potential issues, schedule and monitor service requests, review and take actions for potential security threats, and/or the like. Consequently, users may determine if the door system operates the door in accordance with the desired operating parameters by reviewing the movement, vibration, speed, acceleration, force, or the like based on the sensor information captured and use the information to adjust the door assembly. Notifications regarding the operation of the door systems may be sent automatically and/or in response to requests from users. The users may utilize one or more applications and interfaces thereof to remotely connect to the door systems in order to review and analyze the sensor information and take the desired actions.

Abstract: Door operator systems are described herein that include the use of an adaptor. It should be understood that the adaptor may be utilized in order to operatively couple separate door operator assemblies together in a double door operator system. The adaptor may include control components (e.g., switches, buttons, toggles, levers, or the like) that are used to turn the door operator system on and off. While the adaptor may be used to operatively couple two separate door operator assemblies together to form a double door operator system, the adaptor may also be used within a single door operator system. Furthermore, with respect to double door operator systems, the system may also utilize a back plate assembly comprising two or more separate back plates (e.g., two or more back plate portions).
