Guideline
● External power supply is possible with DC or AC.
● ↑ Floor repeater terminals and ↑ floor repeater displays that are not fed by the
↑ detector line (separate power supply) must be electrically isolated from the
system voltage.
NOTICE
Influencing the earth fault monitoring
Faults
● Electrical isolation of the supply unit must be present for devices on the FDnet
that are fed separately (with the exception of the transponder).
● When an external supply unit is used, it must be taken into account that should
the external supply unit fail, the ↑ maximum current connection factor
increases significantly (line failure is possible).
● When power supply is ensured via the detector line, the high maximum current
connection factor must be taken into account.
● Several floor repeater terminals and floor repeater displays, which are
connected to the same ↑ line card, must not be operated via an electrically
connected supply.
● Only a maximum of eight floor repeater terminals and floor repeater displays
can be connected per FDnet line driver (a line card has one ↑ line driver
featuring two loops) on fire control panels. This results in the following options:
– Fire control panel FC2020 supports a total of eight floor repeater terminals
and floor repeater displays.
– Fire control panel FC2030 supports a total of 24 floor repeater terminals
and floor repeater displays.
– Fire control panel FC2040 supports a total of 16 floor repeater terminals
and floor repeater displays.
– Fire control panel FC2060, without extra line cards (FDnet/C-NET),
supports a total of 16 floor repeater terminals and floor repeater displays.
– Fire control panel FC2060, supplemented by five extra line cards (FDnet/C-
NET), supports a maximum total of 50 floor repeater terminals and floor
repeater displays.
– Fire control panel FC2080, which can be equipped with a maximum of 30
line cards (FDnet/C-NET), supports a maximum total of 50 floor repeater
terminals and floor repeater displays.
● Floor repeater terminals and floor repeater displays are system-wide
configurable.
● A maximum of five ↑ stations can be configured with system-wide ↑ visibility
on the FDnet.
● All other floor repeater terminals and floor repeater displays have visibility to a
maximum of two other stations.
