Enjoy and remember to backup any files that you want to keep!

Update: Had to remove the standalone version as the in-game sirens paired with the Mastercom B went over the game's vehicles.awc file size limit. So the included files replaces the cruiser with the Mastercom and the rest of the sirens with what was in my siren pack as it keeps the file size low enough so it won't mute your game.
