Car Alarms: Siren Chirp, actual sound, ebay

Question
I am so sick and tird of the chip sound in my alarm.  This chirp/sound has been around for 15 years or more, can they not make alarms sound the same??  I've seen some sirens for sale on ebay, will this change the actual sound it makes? THX

Answer
The alarm is not the culprit here. It's the siren
itself. They do make different ones, so it's all a matter
of getting the one you like. I sell one with 20 different
tones you can program for 50 bucks, but there are others
out there.

Most are the 6 tone, but you can tailor some
to do what you like, even talk in some cases.

Get the one you like. Ebay seems like a good place to look.
