FLM‑420‑NAC Signaling Device Interface Modules
General Description
- FLM‑420‑NAC Signaling Device Interface Modules make it possible to monitor and activate a group of signaling devices (NAC = Notification Appliance Circuit) in the Local SecurityNetwork LSN. Each interface module offers one monitored primary line. This means one signaling device line can be connected to LSN fire panels.
- 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
- Available with surface-mounted housing or DIN rail adapter
