Not to my knowledge, but it's possible. There certainly wasn't a radio tower around, but there were antennae all over the place, as there are on any large campus. I don't think that's what was happening; it seemed to be different alarms at different times, but I believe it was always the same song. Which seems to me like they were being randomly selected by a script. These were fancy fire alarms and it was 2014, it's entirely plausible in my mind that they were networked and running a vulnerable embedded Linux. I don't think it'd be a Mission Impossible level effort to make this happen.

But, I'm going off of 8 year old memories, so the only thing I can say for certain is that it happened.
