I have never seen this siren do attack. Great video as always!

Unfortunately I had to go to school and my mom had to record the ambience from my backyard. I was suprised because sirens are not meant to be heard indoors and I heard them at school. I heard the Aca Allertor 125 from Elmwood Park IL, Dunning IL 2001-SRN, River Forest IL T-128. Great recording as always! Love your vids! ❤🎉😊
