Safety Instructions
Functional Description
The FLM-420-RLE-S is fitted with a low voltage relay for connecting one extinguishing system to one LSN fire panel.
Two feedback lines (FB1 and FB2) allow the FLM-420-RLE-S to signal a fault or the activation of the extinguishing
system. On the FLM-420-RLE-S, the fault is indicated by the yellow LED and the activation by the red LED.
The feedback lines can also be used as independent input lines for the supervised monitoring of different
peripherals.
