What alarm system is this going to?

white and blue are the trigger wires that go to the alarm brain the siren itself should have a label to tell you what wires do what

I think the blue gets connected if the alarm puts out a positive signal and the white gets connected if it puts out a negative signal.
You can test it by hooking it up to a battery ,getting the polarity wrong wont mess it up...
