siren replacement

[bulldog5046]

i have to replace the speaker/siren on my Metasystems alarm with one of those ear peircing things that they use for fire alarms in buildings, i know in school we had redicously loud ones that made people wanna move pretty quick and i would like somthing for the car.

i think those are 240v AC so are there any simular in 12-14v DC?

I'm pretty sure 123Db is very loud.

most decent car alarms will be around 120-130db and thats pretty loud,. and chances are the fire alarm you talking about, only sounded louder because you were in an enclosed space,.,
also the fire alarm mightn't be weather proof and their usually white so it'll be easy to see for a thief,.,.
just my 2c,.,.
