Hold-open system
A system for holding open a leaf of a door, of a window, or the like comprises a drive, e.g. a door closer, with at least one mechanical energy storage, which is charged and discharged by an opening/closing movement of the leaf, an electrical energy supply 12, preferably a battery or autarkic supply, a hold-open device with a permanent magnet 16 for holding the leaf open, a triggering mechanism 18 for triggering the hold-open device and releasing the leaf, e.g. in an emergency such as a fire, and a control device 20, wherein the triggering mechanism comprises n≥2 subsystems and simultaneous activation of at least N of these subsystems by the control device wherein 2≤N≤n results in the activating an electromagnet 24 in each subsystem to compensate for the permanent magnet and releasing of the door. Preferably the subsystems are identical and having a functional capacity monitoring system, e.g. at predetermined times or continuously. A method of holding open a door is also claimed.
