Car Alarms: car alarm chirp identification, car alarm, sirens

Question
I'm interested in getting a new alarm for my vehicle but the one I want I can't seem to find. It has a cool chirp and you can hear it in almost any movie where a car has an alarm. I was wondering if you know what chirp and alarm I'm talking about and if you could fill me in on the brand. I don't have a sound clip so if you happen to be watching tv or anything and hear it and can identify it, please let me know.
                      Thanks

Answer
Yes I remember the last few requests you made,
but it's no clearer now then it was then.
Hard to say what you want here. All
sirens have a chirp.

The siren is the part you need. The alarm
can really be anything you like, but the siren
you need is in YOUR ear. I would need to hear
it, like I mentioned the last 2 times you asked.

Tell me the movie (s) perhaps?
