On the section just before the final area where you have to flip the levers with all the turret emplacements, our team went to all the levers and flipped them. No icons left but Cortez kept saying "just one more!". The whole time we are also fighting off antag trying to flip them back up. Only after they were flipped up would we see that icon. Killed antag, flipped switch. Again and again. Elevator stayed closed, time expired. Frustrating end to a hard fought match.
