I've lived in Manayunk for about four years now and every once in a while I hear a loud and large siren sounding. Usually it happen early in the morning and generally sounds three times or so. I have no idea where this horn is or what its for. I assume it's for the fire house. Can anyone explain?

Isn't that avatar from Aqua Teen Hunger Force?

Boxy Brown, baby.

So do you know what that siren is?

I'd guess a fire house if it's long and loud
