The fire alarms have some sort of bad wiring in the circuits, which causes them to malfunction and sound when they shouldn’t.
This morning, a guy from facilities came in and asked if the alarm had been going off today. It had not. Then he and someone higher up in facilities came in and played around with the alarm computer, it started beeping, and a little while later, they left. It has now been steadily emitting a long, high pitched continuous beep for over an hour. Thanks guys. This is why people “go postal.”
