The tag is on what they call an annuciator panel. It monitors all the detectors in the building and its purpose is to show the fire depart where a fire is occurring in the event of an emergency. Every now and then the panel sends out a signal to all the detectors. If the detectors are working properly, then they reply back to the panel. If not, they send a trouble signal.
One of the detectors is a trip switch in the sprinkler pipes. If a sprinkler head goes off the detector reports water movement. It sets off the alarm and a light on the panel shows which head went off. In this case it appears that the panel does a self-test on the flow switch to determine if the water in the pipe is frozen. The device is failing the self-test and so the panel is beeping to let you know there is a problem, i.e. the flow detector is faulty.
This is a life-safety issue and must be fixed immediately. Report it to the Fire Department. I'm sure management will get off its butt after they get a citation.
