INSTALLATION

Note: The installation location should be as flat as possible to avoid warping the housing during installation. If an external power supply is used, the connection wires should be centrally located in the lower third behind the doorbell button.

Opening the Housing

Open the doorbell button by unscrewing the housing screws (4) with a suitable screwdriver (Torx T10) and then carefully lifting the front housing. Be careful not to let the nameplate(s) fall out. Place the front housing and the silicone seal with the nameplate(s) aside to avoid damage during further installation.

Mounting

You can use the rear housing as a drilling template. Align it at the installation location using a spirit level and mark the drill holes with a suitable pen. Drill holes at the marked locations in the wall using a 6mm masonry drill bit and insert one of the supplied dowels into each hole.

Note: If you are not mounting the doorbell button on a stone wall, use appropriate alternative mounting materials (not included).

Thread the connection cable from the back through the cable entry points (9) into the housing. Use the supplied screws to attach the rear housing to the wall.

Closing the Housing

Place the silicone seal with the nameplate(s) in the front housing and assemble both onto the mounted rear housing. Screw both housing parts together with the housing screws.
