Bird Island, MN has 4 sirens in the same area. Their Model 3 was replaced by the adjacent 2T22, which was replaced by the ATI apparently as part of a grant from Minnesota. The ATI proved unsatisfactory for an unknown exact reason, and was replaced with the 2001 as part of another grant from Minnesota. For some reason, none of the old sirens were taken down.
The Model 3's wires were cut, the 2T22 still seems to have power although the antenna on the box was removed, the ATI appears to have power, and the 2001 is confirmed active.
There is also a Federal mini siren on the co-op elevator by the railway.
Federal Signal 2001-130 - Birch St & Main St. This replaced the ATI. Photos taken 10/26/24, copyright Christopher Aylward.
ATI HPSS 16 (feat 2001) - On the water tower at Birch Ave & Main St. ATI replaced the 3T22, and the ATI was itself replaced by the 2001. According to local siren enthusiasts, the ATI was a grant siren from the state. The siren either stopped working or was unsatisfactory, and a separate grant also from the state replaced the ATI with the 2001. Photos taken 10/26/24, copyright Christopher Aylward.
