Was recently taken down from our store where it was used with our security as the siren. The last picture is how my dad had it connected to a battery and to be heard if someone broke in not included only the siren. It was connected on the bottom level to a battery. I know odd way perhaps how we used it lol Originally it came off an old fire truck prior to our use. In great cosmetic condition a few dings I suppose and has the tag attached as well and mount we used it in our store. Last picture is for illustration only and how we used it to work not included with the siren. Very loud siren that is very cool to hear.

Tested on 2/ 26 and have video to provide that it works as soon as you connect cables to it. I had several persons wanted my proof that it works.
