Arena evacuated as broken sprinkler, fire alarm delay CU-Illinois game foxsports Dec 7, 2013 at 12:00a ET Article continues below ... Fans were evacuated from the arena in the first half of Saturday night’s women’s game between No. 11 Colorado and Illinois when a sprinkler head near a loading dock froze, setting off the fire alarm. The evacuation caused a delay of about 30 minutes, but fans were allowed back in, and play resumed with 8:30 left in the first half. The crowd of about 2,000 cleared the Coors Event Center without incident. Earlier in the day, the 11,064-seat arena was sold out for the men’s game – a 75-72 Colorado win over No. 6 Kansas.
