Fire engines were deployed to the Maintenance Building just before midday today, but it was a false alarm.
Two fire engines were sent after a 999 call was made saying there were alarms going off and they could smell burning.
But when the firemen arrived on campus it turned out to be a false alarm.
A Computer Science lecture was evacuated as the firemen investigated the building but it is unknown why the alarms were going off.
A spokesman for the fire service said: “There was a call at 11.40am today to the Maintenance Building on the main campus reporting a smell of burning and alarms going off.
“The emergency call was made by someone with fire safety responsibilities.
“It was a false alarm but with good intentions.”
