To read in the line topology, proceed as follows:
1. Disconnect the detector line or the line section from the control panel.
2. Connect the FDUL221 line tester to the detector line or line section. Adhere to
the polarity [ 47].
3. Switch the FDUL221 line tester on [
4. Check whether 'FDnet ...' matches the detector line. If not, reconfigure the
FDUL221 line tester [
5. Select either 'Startup Loop A->B' or 'Startup Stub A'.
6. Press the button.
The topology is read in and displayed automatically.
7. If you want to assign new line addresses while reading in, then select 'Convert
Line'.
To view the line topology, proceed as follows:
1. Use the buttons to select the 'Devices' sub menu and confirm the
selection with the
The line topology and number of line devices are displayed.
2. Use the buttons to select either 'Devices on A' or 'Devices on B' and

Depending on the line topology, the line devices are displayed.
3. Select a single line device.
The internal and external alarm indicator of the selected line device flash.
If the 'All ON' selection is active in the 'Locate devices' menu, the internal
alarm indicators of all line devices detected by the FDUL221 line tester
flash.
Technical requirements for line topologies
All FDnet/C-NET devices have an integrated line separator. [
Only one stub may branch off between two adjacent line devices.
When there are several stubs next to one another, a line separator FDCL221
must be connected between each one.
The following chapters contain examples for line topologies and the display on the
FDUL221 line tester.
