I have a Viper alarm, and I like it's features, but hate the siren. It sounds just like EVERY OTHER CAR ALARM I'VE EVER HEARD. I'm interested in swapping out the siren with a different one, possibly louder, with a chirp that is more rare... like this maybe:

chirp chirp

Can anyone help??? I know it's neurotic but I am just so damn compulsive about this car; it just can't be too perfect in my eyes.

 

actually that is very distinctive sound.

only dei makes sounds like that....
every alarm makes sightly different noise.

if you work in a stereo/alarm shop you'll know the difference.

 

Viper = DEI

so, you're point is??


albeit, my alarm sounds pretty darn close to that when disarming. it is also a DEI.

 

I tore apart the Viper siren and deleted some tones; this did change the sound of the chirp, but i'm still not happy with it. Thought i'd share some info with those who had the same thought I did:

The speed of the "chirp chirp" is a function of the alarm, not the siren. The alarm plays the first fraction of a second of the first tone the siren is programmed to play. The tones of the siren are a function of the siren only. They can be deleted by taking apart the siren and clipping (selectively) one or more of the six numbered jumpers; they are in a row. A more creative approach might be to re-solder in some jumpers to play tones in a different sequence.
