Larger distances in networks by boards with fibre optics interfaces
Single mode or multi mode? That is the question for all those who have to bridge large distances in fire alarm technology. Using fibre optics technology, networking distances are becoming considerably larger.
Fibre optics networking interface - right from the panel!
The meshed network Integral LAN permits the networking of up to 16 fire alarm panels. Using this technology, multiple and freely selectable topologies as well as multiple links between the individual network nodes can be implemented. And it can still be operated comfortably from one site. Despite its distributed set-up, the system acts like a classical “central” fire alarm panel.
Up to now this could only be done via a copper line, using the RS-485 transmission standard, over a distance of 1,200 meters max. Larger distances could only be covered by using an external converter. For some time now, Schrack Seconet has been offering boards specifically developed for fire alarm panels Integral IP MX and Integral IP CX, making it possible to set up a fibre optics link directly from the panel.
When using the single-mode (FXS) variant, objects up to a distance of 10 kilometres can be integrated into the system without problems. When using the multi-mode (FXM) variant, distances of up to 2000 meters are possible. In addition to these benefits, fibre optics technology also makes possible an increase of transmission speed.
“Only Schrack Seconet offers fibre optics networking directly from the panel without the use of an external converter,” says Andreas Haumer, Product Manager in the Schrack Seconet Center of Competence for the sector fire alarm systems, about the advantages of the new fibre optics networking boards. “This solution is totally new on the market and it will increase security decisively!"
