I have a dei alarm and was wondering how to change the siren tones. Im assuming its in the siren itself since it is only getting 12v or 0v. nothing to tell it what tone to play.

Thanks!

 

that's a nice little write up. but yeah...it's easy, just open it up and cut which ever jumper you want. i have 3 sirens with tones cut so that each siren cycles through different tones at the same time...stupid annoying.
