Two options here folks.
(assuming that the structure is the Ark)
One, Elites control them and that is why the banshees did not engage the chief and they are trying to prevent it from activating. The phantom could contain reinforcements headed to the Ark.
Two, Prophets control them and they just do not care what the Demon does. They beleive that they have already activated the ark.
