To avoid the breakdown of several stub lines in case of a short-circuit, line separators may be inserted. The line separator is used where several stub lines are connected to the FDnet/C-NET at one point. The module can also be connected to 2 separate loops. For retrofitting of existing, collective systems to addressable Sinteso/Cerberus PRO fire detection systems.
The module has total 9 line separators. Each line separator is an electronic switch, integrated into the FDnet/C-NET. It separates the negative conductor in case of a short-circuit, so that the short-circuit-free side can continue to operate. The line separator has connections for the detector lines, connections for the stub lines (T-taps), jumpers for programming of operation mode (1-loop or 2-loop mode), yellow LED for the status indication signals the short-circuit separation.
