Guidelines
● Fire control panels with 512 and more fire detectors (irrespective of the remote
transmission connection) must be equipped with 2 network cards
(SAFEDLINK) (according to EN 54).
● Fire control panels with a central remote transmission connection (irrespective
of the number of detectors in the system) must be equipped with 2 network
cards (SAFEDLINK) (according to EN 54).
● Fire control panels monitoring surfaces larger than 12,000 m
2
must be
equipped with 2 network cards (SAFEDLINK) (according to EN 54).
● A network of up to 32 stations (incl. SAFEDLINK stations) via Ethernet is
supported, but does not meet the requirements of EN 54.
● Furthermore, the fire detection system can be connected to a management
station via BACnet/Ethernet.

C-WEB connection to network card
The C-WEB is connected to the connection terminals on the first network card.
A second network card (SAFEDLINK) can also be used for redundant network
operation (according to EN 54 guidelines).
The first network card must always be fitted on the left space (connection strip
X13) on the PMI & mainboard of the operating unit.
