The newest one being a 2001-130 at a golf coarse just outside of the city.
Here is a reference to a map of Canton's sirens.

Does anybody know what Canton's old civil defense system had?
I think I saw a SD-10 once on a school building on Bing Maps.

Also I saw a Whelen WPS- 2x10 or 2x09 at Timken on Dueber Rd. Is it part of Canton's system too?
