The 2 Wire Network Interface Card allows up to 99 FireFinder PLUS 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 communications to any nodes. The maximum length of cable between each node is 1.2km.
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.
The network also supports compressed file transfer for the application software and configuration file. Using this facility all nodes can have their application software and configuration updated simultaneously. Configuration of the network is handled by the ConfigManager Plus Windows application.
