Jeez, what kind of gas-based fire suppression system shakes buildings and seriously damages equipment?
Well, as I commented in a Contingency Planning report for xxxxxCo some years ago "I have been unable to confirm the Ops. dept. claim that soldered 15mm copper tubing can handle the release of unregulated CO2"

.... but when halon was banned for refrigeration, some cowboys started using butane (works very well unless you get a leak!).
Surely no-one would replace fire suppression gas with butane....
