Loop planning
Note the following if there are several FDC modules:
For improved safety, FDnet loops that are as independent of one another as possible should
be applied to different modules.
The loops should also be distributed over different modules when using alarm sounders
and signal bases as evacuation alarms on the loops, in order to improve the safety of the
acoustic alarm.
Examples:
•
In buildings with several storeys, apply the loop of one storey to one FDC module and
the LOOP of the next storey to another FDC module.
•
In the case of large buildings with multiple loops, distribute these alternately over two
different FDC modules.
