It isn't in the book but rather in the dialogue between 2401 Penitent Tangent, the Arbiter, and Miranda Keyes after the deactivation of Delta Halo.
It goes something like this.
"All of the rings go on standby status for remote activation"
"And where, Oracle, would someone go to remote activate the rings?"
"Why, to the Arc, of course"
---I know its not word for word so don't bother to correct me.
