Sinteso backbone (FCnet/LAN)

Clusters can be networked via an Ethernet backbone, using industrial LAN technology.

Siemens is the first manufacturer who offers this as EN 54-approved solution. With standard IT architecture, building structures and organizational processes can be ideally represented.

Characteristics of networking via backbone

  • Ethernet switch to connect a cluster (FCnet/SAFEDLINK) to the backbone (FCnet/LAN)

  • Redundant transmission thanks to circular wiring

  • Redundant connection possible due to two Ethernet switches

  • Increased EMC protection thanks to fiber-optic cabling

  • Easily programmable, EN 54-compliant system-wide control

  • Configurable view of each panel

  • Each panel can be used as a router panel (please read separate documentation).

Key data

  • Max. number of panels in EN 54 system: 64

  • Max. number of panels in a cluster: 16

  • Max. number of networkable clusters: 14

  • Number of panels placed directly on backbone: 4*

  • Number of panels with system-wide view: 5*

  • Max. distance between Clusters:
    - Fiber optic multi mode (FN2012-A1 with Ethernet module (MM) VN2002-A1): 4.000 m
    - Fiber optic single mode (FN2012-A1 with Ethernet module (SM) VN2003-A1): 40.000 m

* more with appropriate system topology

The following guidelines must be considered

  • To fulfill the EN 54 norm, only 1 Ethernet switch is required to connect control panels with less than 512 fire detectors to the backbone
