I'm planning on doing some new stuff with my security system in the near future, and I was curious about how exactly a siren chirps on lock and unlock.

Does the alarm brain just send two quick +12 volt pulses to the siren output on unlock? Or are they a different voltage, or what?

I'd go out and test the siren on my car with a multimeter, but my siren is incredibly hard to access(and so is my alarm brain.) So I'm hoping someone can help me out. >>

Thanks,

My *guess* would be that its a certain voltage which is sent the number of times the brain wants it to chirp. That would be my 2 cents.

I could maybe try to find a multimeter and test this, I dont know if I have one I'd have to find out. My alarms currently out because I lost the remote and didnt even know what alarm I had (was in there when I bought it.) Its an old Viper 300ESP with window roll up and proximity sensor expansion packs.

its a burst of 12+ volts. when i hooked up the back up siren i had to test it out. >>

well if u have the DEI siren it is 12 volts that go through the certain resistors that make the diffrent sounds. you can open up a DEI siren and cut the sounds u dont like.

Thanks for the help. >>

I've got four sirens at the moment...an Alpine, an Autopage, a universal(don't know what brand), and this other one...I forgot the name, but it's crazy loud and plays multiple siren tones at once and sounds like multiple sirens. But anyway, as long as +12 volt pulses are sent from the alarm brain, I'll be fine. >>

Thanks again.

Dont be afraid to add more then 1 siren either coomer. I got 2 pain generators in my interior, but a regular siren under your console would hurry a bugular out of there. Ebay also cheap for your 520 or 530.
