8.16.1.1 Guidelines for a station's redundant SAFEDLINK
connection
A ↑ station is incorporated redundantly into the ↑ SAFEDLINK network if two
network modules (SAFEDLINK) are used. The stations' redundant SAFEDLINK
connection complies with EN 54 and is specified for the following applications:
● Fire control panels with more than 512 fire detectors (irrespective of the remote
transmission connection) must be equipped with two network modules
(SAFEDLINK) (EN 54).
● Fire control panels with superordinate functions (remote transmissions,
alarming devices, master operation) must be equipped with two network
modules (SAFEDLINK) (various country-specific 'Codes of Practice').
● Fire control panels monitoring surfaces larger than 12,000 m
2
must be
equipped with two network modules (SAFEDLINK) (VDE 0833-2).
● The fire control panel FC2080 may monitor a surface of more then 48000 mm
2
in redundant ↑ CPU operation (2 CPU cards with network module).

The redundant display can be realized using a fire terminal or a fire control panel.
A redundant SAFEDLINK connection is not required in the redundant display.
