9.2.5 Network tree
The ↑ network tree represents the networking of an FS720 system.
Networking types
The ↑ stations in the fire detection system can be networked in the following way:
● ↑ SAFEDLINK (↑ system bus)
● SAFEDLINK, extended: Coupling of several SAFEDLINK sub-nets via C-
WEB/LAN (optical Ethernet)
● Electric Ethernet (does not comply with EN 54)
● SAFEDLINK and Ethernet mixed (does not comply with EN 54)
Connection types/functions
The ↑ stations in the network can have the following connection types / functions:
● ↑ Standalone station
● ↑ SAFEDLINK station: Station in the SAFEDLINK network
● ↑ Router station: Station in the SAFEDLINK sub-net connected to the C-
WEB/LAN
● ↑ Ethernet station: Station in the Ethernet sub-network to which no more
stations are connected via SAFEDLINK
● ↑ GAP station: Station in the network for connecting to a ↑ management
station (↑ BACnet client)
– The GAP station has the function of a DHCP server (configurable)
– The DHCP server automatically issues IP addresses to the clients from a
defined IP address space. This enables a PC to receive local access, for
example
● A route to an external IP router can be defined for the GAP station
↑ Extended networking
Extended networking is the merging of several SAFEDLINK sub-nets via C-
WEB/LAN, which is managed as optical Ethernet in loop topology.
The sub-nets communicate via the ↑ router stations.
Private/external network
● Private network: FS720 fire detection installations have their own cabling. The
IP addresses come from a reserved range for private networks
● External network: Fire detection installations can be incorporated in an existing
IT infrastructure as sub-nets
● Integration in an external network does not comply with EN 54
Connection with management stations
The connection between management stations or other sub-systems and the
FS720 sub-system is established via ↑ BACnet / Ethernet.
A management station is connected to the FS720 sub-system via the ↑ GAP's
Ethernet interface. Every single station that is to use the BACnet protocol must be
enabled with a ↑ license key. The license key must support the BACnet function for
management stations.
