摘要： The present invention relates to a blocking device (4) for a damper drive, wherein the blocking device (4) can be transferred by activation from an inoperative state into an alternative activated state. The blocking device (4) comprises a movably mounted blocking element (41) which, in a blocking position, blocks an output member (13) in a safety position. The blocking device (4) further comprises a drive element (42) which, when the blocking device (4) is activated, moves the blocking element (41) into the blocking position. The blocking device further comprises an activating element (43) which, when a blocking temperature has been exceeded, activates the blocking device (4) by an irreversible change in shape. Also disclosed are a damper drive with a blocking device, a fire protection device and a method for operating a fire protection device.
