Abstract

A fire suppression sprinkler assembly coupled to a mounting surface includes a sprinkler having a heat responsive element arranged adjacent a first end. A cover plate is positioned adjacent the heat responsive element and includes a thermally conductive cover layer. A reflective shield has a reflective interior surface. The reflective shield is positioned substantially opposite the cover plate adjacent the first end of the sprinkler such that heat reflects from the top plate towards the heat responsive element.
