OMAHA, Neb. (AP) — The University of Nebraska at Omaha has been fined $900 for false alarms at Baxter Arena, which has been open to the public for less than a year.

University spokesman Charley Reed said that “fire-alarm sensitivity has been an issue at Baxter since it has opened” but also says they’ve been infrequent. City records say there have been five false alarms since September 2015.

Associate athletic director Mike Kemp says the problem occurs when the scoreboard is moved up and down. He says the university will get the problem resolved.

City Treasurer Donna Waller says no fines were issued for the first two false alarms. False alarms on Oct. 5 and Jan. 22 drew $200 fines. A fifth alarm on April 13 cost the university $500.
