Based on this statement
“FM-200 these types of suppression systems fill the room with an inert gas that puts out the fire without damage to equipment or occupants.”
from this site:
I’d say there would be no damage (other than fire related damage…)
As far as inadvertent activation, I’m not sure… When was the last time your fire alarm system was falsely triggered? That would be a factor of the triggering system and the environment that it is in.
