1200C-2000C Fire Alarm Control Panel, Repeater, and Black Box Installation Manual 13
Connecting the NC2011 and NC2051 network modules
The NC2011 and NC2051 network modules enable a wide range of network
topologies when networking 1200C-2000C control panels and repeaters.
The NC2011 and NC2051 modules are located on the inside of the control panel door
(top layer) and connected to the FC1200N or FC2012 host CPU module.
General information
All network nodes use the ARCNET protocol. Every node on the network must have a
network module installed.
Where cabling runs between buildings or in high-noise or harsh environments a fibre-
optic network should be used.
