The SK-NIC enables a common communications and annunciation link to be created
between up to 17 panels. A designated panel is configured as the communicator for all
panels in the link for convenient single-point communications.
The SK-NIC provides a common communications link for 6700, 6808, 6820 and
6820EVS panels. However, they cannot be linked together for peer-to-peer networking.
The SK-NIC card comes standard with network connections using unshielded, twisted-pair,
copper wire. For fiber optic networks, optional single-mode and multi-mode fiber-optic
network add-on modules are available.
