10.9 Line adapter (Ex) FDCL221-Ex
Device for zone 0, 1 and 2 areas at risk of explosion
10.9.1 Functions
● The line adapter (Ex) is used for electrical isolation purposes and for limiting
the electrical energy between non-intrinsically safe and intrinsically safe
circuits.
● It is not necessary for the housing to be connected to local ground
● The power required for the line adapter (Ex) to supply itself is taken from the
FDnet. It is not necessary to connect an external power supply
● Operation possible on an FDnet detector line or a stub. There is therefore no
line separation function in the area not at risk.
● The line adapter (Ex) has two connections for the detector line (FDnet) in the
area not at risk and one connection in the area at risk of explosion (FDnet-Ex).
● Two LEDs for displaying the operating status and faults, and for localizing the
device
Observe
national guidelines and regulations.
● Fields of application:
– The line adapter (Ex) must not be mounted in the area at risk of explosion.
– The line adapter (Ex) is used where the operation of Ex peripheral devices
is required. It separates the area at risk of explosion from the area not at
risk
– The line adapter (Ex) only makes it possible to operate FDnet-Ex and
C-NET-Ex devices There are other safety barriers (SB2, SB3) available for
collective systems
– Changing from existing collective systems to addressable Sinteso and
Cerberus PRO fire detection systems
