MINERVA MXNet Inter-Controller Network

MXNet allows MX fire controllers to be drawn into a network system. Because every installation is different, MX Net has been designed to be highly flexible, allowing for a wide range of different systems applications.

With a large network system the amount of data and information passing between fire controllers can become high during an emergency condition.

The MXNet communication protocol has been specifically designed with this in mind and ensures that each event message passed around the network is acknowledged by the receiving controller in the fastest possible time.
  • Allows MX Fire Controllers to be “seamlessly” networked together
  • True peer-to-peer communications; no host or master controller required
  • Highly resilient, node failure open and short circuit does not affect remaining network
  • Designed to comply with BS5839:Pt. 4: 1998
  • Up to 99 controllers may be used on the network
  • Wide range of cable topography supported
  • Network can use standard 1.5mm MICC cable
  • Easy to install and programme
  • Simple to operate
The network is totally flexible and enables from 2 to 99 fire controllers to be linked together, providing a system capability of up to 23,760 fire zones with 99,000 detection addresses, and over 49,000 digital I/O points.

The MXNet communications network comprises a collection of network interface modules and peripheral equipment that together form a fault resistant, and flexible peer-to-peer network for the MX Digital addressable fire systems controllers.

With MXNet, each MX Fire Controller on the network permits an operator to interrogate and control any other MX Fire Controller on the network For extended interrogation and control, MXNet allows for up to a maximum of five nodes on the network to be configured either as Master operating stations or MXGraph, Graphical user interfaces.

Master operating stations use the standard MX Fire Controller hardware. In this application, the controller changes its personality; and enables additional information from each controller on the network to be displayed.
