Abstract

A fire protection securing apparatus for securing a door actuator includes a retaining plate, designed for being secured to an assembly surface, in particular door, frame or wall, wherein, perpendicular to the retaining plate, an assembly axis is defined. The fire protection securing apparatus further includes an assembly plate which is secured to the retaining plate and which is designed for receiving the door actuator, and at least one closed reaction chamber arranged between the retaining plate and the assembly plate. The apparatus also includes a drive element of thermally intumescent material which is arranged in the reaction chamber and which is designed to push the assembly plate away from the retaining plate upon thermal activation.
