What system does your city have?
Hartford CT: mostly Federal Thunderbolts 
Stamford CT: Thunderbolts.
Meridan CT: Thunderbolts :BNC
New Haven also has those T-Bolts. :BNC:
We never have tornado(e?)s where I live, but we do have some kind of warning siren.
I’ve located one, and it’s located on a building not far from where I live ;D
I don’t know what kind it is tho.
Cheers,

Is it a Federal Signal or Whelen?
