I live in Plymouth, and am almost positive this siren is no longer active, although it is still mounted at city hall. Plymouth currently is all Thunderbolts, except for this siren(inactive) and one FS 2001 at the municipal yard. My theory is that a few years ago when the city looked into replacing the Model 5, they decided to place it in a new, most likely more effective, position, which is the municipal yard. The municpipal yard is roughly a half mile or so from city hall.500at
First off, The siren located at the Plymouth City Hall is a 12 port, Federal Model 5A, and used to be run for fire and tornado alerting. They even used it to announce the start of the July 4th parade, but I am not certain if it's even operable any longer.
