Federal Signal 3T22 Eagle Lake, Minnesota | Alert & Attack | 8/4/21 AUDIO ONLY

Awhile back, my uncle recorded a 3T22 in Eagle Lake. It's only audio, so yeah. Eagle Lake has two other sirens, an Eclipse, and a STH-10. The Eclipse replaced a 3T22. (Btw, that Erick used to do noon blasts, but has been silent for the past years. I got to hear one of its last noon blasts awhile back.)
Information about this siren:
Manufacturer: Federal Signal (could be FS&S)
Model: 3T22
Port Ratio: 10/12
Status: Active
Color: Yellow
Location: Eagle Lake Fire Department, Eagle Lake, Minnesota
Coordinates: 44.16426, -93.8842
Date Recorded: 8/4/2021
Testing Time: Blue Earth county tests their sirens at 1:00 PM on the 1st Wednesday of every month year round. Sirens will test a one minute steady signal, one minute of silence, and one minute of the attack signal.
Additional Details: Replaced an Erick that sits on top of the fire department. As far as I know, this unit only sounds hi-lo during fire calls.

From what it seems now this thing is replaced with a Whelen vortex
