Abstract
A fire protection fastening device for fastening a door actuator, includes a frame with a back side, which is to be oriented to a mounting surface, in particular to a door, casing or wall, wherein a mounting axis is defined vertically to the back side. The frame is formed for arrangement between a door actuator and the mounting surface or is an integral component of the door actuator (102), at least one reaction chamber formed in the frame, wherein the frame delimits the reaction chamber on the entire circumference. The reaction chamber is open on the back side and/or on a front side of the frame opposite the back side. The device further includes a drive element made from thermally intumescent material disposed in the reaction chamber and, when activated, is formed for pushing away the door actuator from the mounting surface.
