NC2011/NC2051 ARCNET network cards

The NC2011 and NC2051 are interface cards required to network FP2000 Series fire
panels and FR2000 Series repeaters/emulators. All network nodes communicate via the
ARCNET protocol, using RS485 electrical (NC2011) or optical medium (NC2051). Every
node on the network - except the UN2000 - must have a network card installed as a
standard. The PCB is delivered with the necessary washers, nuts and spacers to allow for
proper mounting. All repeaters/emulators are supplied with a standard NC2011 (RS485)
network card. For more information refer to the Network Configuration Guide.
