FLM-420-NAC Signaling Device Interface Modules

  • Rotary switches for automatic or manual address setting
  • Control of signaling device line by pole reversal
  • Synchronized activation of all signaling devices connected to a LSN module via FLM‑420‑NAC Signaling Device Interface Module
  • Ten different output signals via LSN selectable
  • Maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators
