While CRACs won't recirculate oxygen, they can move air past sprinklers faster than they can handle which can delay operation, typically 5 fps. Although that's only if you are using sprinklers, clean agent is a different matter.

Yep, it is part of the design. The sprinklers are sometimes pre-action like described in the article, and sometimes clean agents. The only time we shutdown CRACs is if we EPO the whole room because otherwise some variant of this article happens.
