Mystery Police Siren

[Fanman]

I've had this police siren for 2 years and I still am clueless as to what it is.
Hope the images work, I'm still new to the system.





I hope you guys might have an idea

EDIT: one of the images doesn't work. Sorry

I did some research and I believe your siren is a University Sound DLC-T 7.5W.
Here is an eBay link to one for sale:

how loud would it be on 12 volts because I'm currently running it on 7.5 volts and it's loud, but not as loud as my hand crank siren.



EDIT: Thanks for saying what it is. I hooked it up to my homemade 7.5 volt FM radio and it's way louder than it used to be lol

Also all the pictures of this siren say it's a loudspeaker. Is it just a small PA speaker or a police/firetruck siren?

On this eBay listing for a very similar one, the manual calls it a paging/talkback speaker.
