It's not like they constantly go off, but when they go off once, it's a pretty safe bet they'll go off at least once or twice more within the hour:/
I think the sensors on the alarms are programmed to be too sensitive. That and the fact that they're renovating the building (while students are living there) and kicking up a lot of dust and setting them off. And apparently if people don't shut the bathroom door while showering, the heat generates steam that also sets them off.
Happy Birthday, BTW, and sorry for ranting about my fire alarm woes on your big day xD
