Siemens FDCIO361 Input/Output Module (1 Input and 1 Output)

The Siemens FDCIO361 is an addressable single-channel input/output module designed to monitor potential-free contacts and trigger auxiliary fire safety devices. Operating on FDnet/C-NET loops, this compact module combines 1 monitored input and 1 potential-free relay output to connect equipment such as sprinkler flow switches, fire doors, smoke dampers, and ventilation systems directly to the fire panel. Its input line is continuously supervised for open and short-circuit faults, while the relay output provides dependable switching for building control interfaces. Built with an integral line separator to maintain loop communication during wiring faults, automatic soft-addressing, and onboard status LEDs, the FDCIO361 provides efficient, reliable monitoring and switching performance for modern fire protection systems.
