Wiring
NÜO SURF readers can be directly connected to two types of devices depending on the architecture of
the installation:
- Connection to a Wili.
- Connection to a single door controller.
The connection to be made for both types of devices is exactly the same. The colour code must be
followed. For more detailed information, consult the equipment manuals referenced earlier.
READER WIRING:
Install and connect the reader before powering the system.
NÜO readers use the 24 vDC input voltage corresponding to the controller equipment to
which they are connected, and whose power sources are rigorously prepared for
this purpose.
These signals must be perfectly isolated in order to prevent damaging the equipment
or installation.
