343GS seems to make reference to being questioned before the original firing of the Array, which could be why people think it was fired from Installation 04.
It's possible, however, that this questioning took place at another place, or perhaps on Installation 04, but at a time before the Array was fired.
From what I remember of the terminal messages, they seem to suggest that it was the Ark that was the final turning point in the battle against the Flood, so it would make sense for the Array to have been fired there.
