Siemens FDCI222 Input Module (4 Inputs)

The Siemens FDCI222 is an addressable input module featuring 4 independent monitored input channels designed to interface potential-free contacts with a fire detection system. Operating on FDnet/C-NET loops, this multi-channel interface allows the main fire panel to monitor technical status signals, sprinkler contacts, flow switches, and status feedback from external equipment. Each of its 4 independent inputs is continuously supervised for open and short-circuit faults, while an integral line separator isolates wiring faults to prevent loop failure. Programmed automatically with unique addressing via the panel software and featuring onboard LED indicators for quick visual diagnostics, the FDCI222 provides a compact and reliable input expansion solution housed in a protected enclosure.
