The canopy for the door intercom systems TFS-Dialog 100/200 is mounted behind the door intercom unit and protects it from direct weather influences such as rain and snow. As a natural material Anodized aluminum is also used (see right). In addition, the canopy can also be used to cover too much wall openings. These additional holes are present, for example, to cover dialogue already existing flush module support the older door intercom system TFS 2616 and TFS and fasten the canopy directly to the existing carrier.
