Citizen complaint of the day: The screaming alarm of Chinatown

A weary-eared citizen complains about the alarm system at the Empire Garden dim-sum place on Washington Street, kitty corner from Lagrange:

The alarm from this building has been going off every night for the last week and no one comes to turn it off. There are many residents complaining about it going off for many hours at a time. It has a bull horn pointed out towards the street.
