You must use Parameter 37 to change the tone and volume of the Siren. In order to make this setting change, your gateway must support the Configuration Command Class otherwise this is not possible.
By setting Parameter 37 [2 byte hex] using the list above, you would set it as 0x[value1][value2]
So if you want sound 3 with volume of 1, then you would set Parameter 37 [2 byte hex]: 0x301
If your software or gateway does not use hex values, you can take any Hex to Decimal calculator to change this. http://www.binaryhexconverter.com/hex-to-decimal-converter
