SIEMENS FP2005-A1

In complex or multipoint installations — such as apartment complexes, large commercial buildings, educational campuses or industrial facilities — it’s essential that all fire‑alarm panels communicate seamlessly to ensure centralized monitoring and coordinated alarm handling. The FN2001‑A1 module enables exactly that by connecting multiple panels into a unified network (via SAFEDLINK / FCnet / C‑WEB), allowing up to 32 panels to act as one integrated system. Because the module provides electrical isolation between the system bus and each panel, it reduces risk of cascading failures or interference, maintaining system integrity even under fault conditions.

Moreover, FN2001‑A1 includes built‑in ground‑fault supervision and a degraded‑mode function: if a wiring fault or line break occurs, the module automatically transfers signals to maintain communication. This fault‑tolerant networking makes the system far more reliable than basic cascaded panel setups or standalone fire‑alarm panels. The plug‑in module design ensures installation is quick and neat — simply slot it into the designated network slot (X13) on the mainboard/PMI. For building managers, installers or safety engineers, FN2001‑A1 simplifies the challenge of scaling fire‑alarm infrastructure: instead of separate, disconnected panels you get a cohesive, supervised network ensuring consistent coverage and central control.
