Siemens FCL7201-Z3 FDnet Line And Address Expansion Card (SynoLOOP)

The FCL7201-Z3 SynoLOOP card is a module data bus card installed in card-cage fire control panels and adds four loops to the panel. When capacity requirements grow, expansion is performed by adding cards instead of replacing the entire control station. This approach makes it possible to expand the fire system without stopping it in an operating facility and extends the investment lifespan.
