thunderbolt 1003 FAIL? with 2001 ambenice wilton iowa 5/6/24

so i did it this is the first wilton iowa siren ambenice and test
sirens in this video
federal signal thunderbolt 1003 failed? 489 FT away from recorder
federal signal 2001-130 at the end of Sycamore St 0.5 miles away from recorder
federal signal 2001-130 at westview park failed 1.2 miles away from recorder
also this is the first 2 sirens that have failed on me i don't know if the thunderbolt goes off (the yellow one) thats why i put a question mark there
recording location wilton Historic Depot
another thing it was very hot there i was in the sun and i had a nasty sun burn from the day before
if theres more i will add it but other than that it was a nice day and a good test other than the 2001 at westview park failing
does the thunderbolt 1003 go off for noon blasts or fire calls?
ALSO this is the first ever siren recording of wilton iowa i was the first YAY!
