The Ad-NeT network system allows all MxPro 4 series control panels, remote terminals and network peripherals to be connected together using standard fire resistant two-core cable. It provides both the benefits of distributed intelligence and reduced installation costs whilst catering for the smallest 2-Panel network through to the largest 200-panel wide area networked system. The network operates as a true peer-to-peer system allowing information from any input or output device to be passed over the network and displayed on any MxPro 4 control panel or remote terminal as required.
