The Network Interface Board allows up to 99 FireFinder Marine panels (nodes) to be connected in a high integrity redundant network configuration. The network is capable of withstanding an open or short circuit fault without the loss of communication to any nodes.
The network operates as a peer-to-peer network, with all device state changes shared over the network. Each node can be configured as to which state changes are displayed. This configuration is specified in terms of nodes, loops, or groups.
