I asked DSC tech support about that some time ago.  They said it
is not recommended to draw more than 700mA from those terminals.
I asked about the 3 Amp limit and they said that is for "brief
periods".  Asked if a typical siren timeout of 4 minutes would be
excessive the tech said yes.

You should add the DSC auxiliary power supply to your system.
That will give you more power and the ability to switch your
powered outputs, nice for driving multiple sirens, strobes, etc.
