3.2.4 Adjustment elements

The multi line separator module has four jumpers, J1...J4. These jumpers can be

used to configure whether the FDCL221-M is to be operated in one FDnet/C-NET

loop or two FDnet/C-NET loops.

Jumpers J1...J4 have the following two plug positions:

1-loop operation 2-loop operation

The jumpers are plugged on 1-loop operation when delivered.

3.3 Function

The multi line separator module FDCL221-M has several electronic switches

(line separators). The following operation modes can be configured using jumpers:

● 1-loop operation

(9 line separators in one FDnet/C-NET loop)

● 2-loop operation

(4 line separators each in two FDnet/C-NET loops)

The function of the line separator in the FDnet/C-NET loop is to connect sub-stub

lines to the FDnet/C-NET and selectively disconnect them in the event of a short-

circuit. In the event of a short-circuit the line separator disconnects the affected bus

area in the FDnet/C-NET so that the area unaffected by the short-circuit continues

to function.

The multi line separator module has 2 x 4 screw terminals for the FDnet/C-NET

loops and a 20-pin connector with socket strip for the ten sub-stub lines. A

maximum of two different loops can be connected.

The status of each line separator is indicated by a yellow LED. The LED flashes if

the line separator is open or in localization mode.

The multi line separator module is installed in the intermediate distributor or directly

in the fire control panel.

NOTICE

Incorrect use

False alarm caused by potentials moving in the event of external supply on the

sub-stub via a FDnet/C-NET card.

●

Sub

stubs may only be fed via the line separator.
