Quench protection systems are an indispensable asset for the safety and integrity of the components of the FCC superconducting circuits. This contribution focuses on the quench detection (QDS) system. A design study for the QDS proposes main processing units located outside the FCC tunnel and interconnected with high-speed data links to intelligent sensors with reduced complexity and hence increased resistance to higher radiation levels. This will allow for the adoption of a software defined approach for quench detection, while the centralization will improve noise suppression and increase the accuracy by correlating multiple channels. Additionally, the proposed approach facilitates implementation of novel quench detection techniques for the future superconducting magnets.
