As others have said, use 240. I am certain your house has it, I do not know of anywhere in the U.S. Where 120 residential services exist at this point. Additionally I would be very hesitant to run a siren on a static converter. That type of converter only develops around 70% of the motors power. Siren motors seem to be sized right on the line and if anything a bit undersized since they arn't expected to run for long periods. If you use a static converter you have a high chance of burning out the motor. Use a rotary converter, VFD, or generator. Even with a rotary there would be risk of damage, but a lot less especially if well balanced.
