8. Installing the Outdoor Unit
a) General Information
The outdoor unit should be installed in the protected area, e.g. next to the entrance door (e.g. under an
awning), so that the visitor is standing right in front of it when he pushes the button.
The radio range between the outdoor unit and mobile unit is up to 200 m.
However, the range values refer to the so-called „free field range". (Range in case of direct sight
contact between transmitter and receiver without any interferences).
In practical operation, however, there are walls, ceilings etc. between the transmitter and the
receiver which reduce the range correspondingly.
Due to the different influences on radio transmission, no specific range can be guaranteed, un-
fortunately. Usually, however, operation in a family home is possible without any problems.
b) Attachment to the Wall, Connection
Proceed as follows:
• Remove the cover above the terminal block (9) by turning out the 4 attachment screws of the cover.
• If you want to operate the outdoor unit with batteries, remove the associated cover of the battery com-
partment by turning out the 4 attachment screws.
Observe that some functions are not available in battery operation to save power. For example,
button lighting and the door opener are not available. You also cannot activate the camera image
from the mobile unit.
Therefore, we recommend only operating the outdoor unit with an external voltage/power supply
(9 - 12 V/DC, at least 1.5 A).
• Choose the mounting height so that the camera points at the visitor's face.
Attach the weather protection frame of the outdoor unit to the wall with two suitable screws and poss.
dowels. The weather protection frame has the corresponding opening at the bottom.
