FLM-420-I8R1-S Octo-input interface module with relay

  • General Description

    • The FLM‑420‑I8R1‑S Octo-input Interface Module with Relay allows the monitoring of up to eight inputs. Additionally, it features a change‑over contact relay for providing a potential‑free output contact. It is a 2‑wire LSN element. When connected to the fire panels FPA‑5000 and FPA‑1200, the interface module offers the enhanced functionality of LSN improved technology.

     

  • Features

    • Individually selectable monitoring functions (EOL or contact) for the eight inputs each 
    • Maximum switching capacity 2 A / 30 V DC or 0.5 A / 42.4 V AC 
    • Maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators 
    • Easy wiring thanks to pluggable terminal blocks
