Abstract

A backplate for a door actuator, includes at least two mounting elements, one of the two mounting elements being formed for fastening to a mounting surface, in particular door, casing or wall, and the other mounting element for accommodating the door actuator. The backplate further includes at least one connecting assembly with a bar element mobile disposed at the first mounting element and a thermally activatable trigger element. The bar element is movable from a retaining position to a release position. In the retaining position, the bar element retains the second mounting element and, in the release position, releases the second mounting element. When thermally activated, the trigger element releases a movement of the bar element to the release position and/or, the trigger element moves the bar element to the release position.
