The NK8225 configuration is part of the Composer tool environment. To perform the
SW-configuration for NK8225, a WW8000 Composer license is required.
The configuration tool includes connection parameters, as well as interaction parame-
ters (with AND, OR, XOR, and NOT logic combinations).

–
8 input (non supervised) module for acquiring digital contacts. A
max of 2 modules can be directly connected to NK8225. For
more connectivity (as well as for supervised inputs), it is neces-
sary to use a CF9003 CPU on one of the serial connections.
–
8 output (non supervised) relay module for controlling digital con-
tacts. Only one module can be directly connected to NK8225.
For more connectivity, it is necessary to use a CF9003 CPU on
one of the serial connections.
–
Optional module for supervising the NK8225 power supply and
detecting power failures and battery low conditions. It is not
needed when NK8225 is installed in a fire or intrusion control
unit, whose power supply is already supervised.
