SIEMENS A5Q00009875

The A5Q00009875 line card (FCL2001‑A1) solves a common problem: when a building’s fire-detection needs exceed the capacity of the base control panel. Instead of replacing the entire panel, this module lets you expand existing fire alarm infrastructure — adding new loops and supporting more detectors or devices. This makes it ideal for growing buildings such as multi‑floor offices, schools, hospitals or large residential complexes. Because it supports up to 252 device addresses per card and offers 2 loops with 500 mA output, you can connect a substantial number of sensors, detectors, manual call‑points, or sounders. The modular, plug‑in design means installation and upgrades are quick, cost‑effective and less disruptive than rewiring or replacing full panels. Its compatibility with FDnet / C‑NET and systems like Cerberus PRO ensures you can integrate it seamlessly into an existing SIEMENS fire‑safety setup. Compared with adding standalone detectors or smaller expansion kits, A5Q00009875 provides a more scalable, robust and professional‑grade solution — giving building managers flexibility to expand coverage as their safety needs grow, without sacrificing reliability or compliance.
