In August of 2022, I filmed this same siren at a different spot but I wasn't present at this siren at the time cause I was at the Fire Hall Thunderbolt 1000T that day. Because now that I've got all the sirens in Deerfield Twp filmed, I wanted a chance to actually hear this STH-10 up close in person and I enjoyed it. A young siren enthusiast was also present during this test but I didn't stay long cause I had to fetch my cameras that were filming the background sirens.

Here is a map of all the confirmed sirens located in Deerfield Township, Michigan. https://www.google.com/maps/d/viewer?...
