At any rate, firing the Halo array might not even be possible anymore since the Ark was destroyed.
I don't think so. Halos can be individually activated. I assume the Didact himself could've retrieved the index, moved the ring, and fired short-range pulse in the Sol system if he wanted to. He wanted to trap humanity though. Imprison them in the data centers of the Composer, and then use them to raise his own Promethean Knight army.

Anyways, the Ark in Halo 3 is just a manufacturing station. It's designed to build Halos using captured moons or planetoids. And it's not the only one. Sure it can activate them remotely and simultaniously, but it isn't required to activate the installations. Each can be activated manually.

Just pointing that out.
