4.4. PPIC35520
This intercom is particularly well suited to retrofitting. It can usually be wired using the existing cabling
if the existing doorbell is replaced. Use an ammeter to check whether there is sufficient voltage in the
existing cables. Otherwise, the power supply will have to be installed separately. You will find further
details and illustrations of the exact wiring below.
4.4.1. Mounting plate
First, separate the mounting plate from the door station. Place the mounting plate in the desired
installation location, and mark and drill the required holes. For the best field of view, we recommend an
installation height of at least 1.3 m (4.25 ft). Insert the screw anchors provided. Next, run the existing
or replacement cabling through the ring opening on the mounting plate. We recommend you use the
rubber ring provided for better protection against water and other fluids. Perforate the ring at the
specified points in order to run the cable through, and place the ring in the ring-shaped opening in the
mounting panel. Then use the screws provided to fix the mounting plate in place.
4.4.2. Preparation
When shipped from the factory, the door station is connected to the call button cover, the call button
pressure plate and the cover. To continue installation, first remove the call button cover, then the call
button pressure plate. To remove the cover, exert a little pressure on the call button area, which should
now be easily accessible, and pull the cover upwards and away from the door station
