A Total Flooding System discharges a gaseous suppression agent to fill an entire enclosed volume to a design concentration, extinguishing fire throughout the space rather than at a point. In a data center, clean-agent and inert-gas systems operate this way, requiring a sealed room whose integrity is verified by a room integrity (fan) test so the agent concentration is held for the required hold time.
