  • MODULAR HOLD-OPEN DEVICE FOR DOOR CLOSERS
    Publication number: 20230313585
    Abstract: An exemplary modular hold-open device is configured for use with a door closer comprising a body, a pinion rotatably mounted to the body, and an armature connected with the pinion. The modular hold-open device is configured to be mounted to the door closer, to selectively prevent rotation of the pinion by exerting on the pinion a resistive torque in a door-opening direction, and to cease exerting the resistive torque in response to a door-closing torque on the pinion exceeding a threshold torque to thereby permit rotation of the pinion in the door-closing direction.
    Type: Application
    Filed: December 6, 2022
    Publication date: October 5, 2023

  • Exit device systems and methods
    Patent number: 11255109
    Abstract: An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism. The exit device is configured to locally analyze sensor data to determine the security state of the exit device, report data to a management system via a wireless communication channel established between the exit device and the management system, and receive and process instructions to perform an electronic dogging operation.
