If you have a home alarm system you should filter it just as you would a telephone or Satellite receiver connected to your phone system. If the alarm system is not plugged into a phone outlet (most likely) a special DSL filter can be purchased that you can wire between the alarm system and the rest of your phone system. (Wire similar to a home run, separate the DSL signal from all other devices hooked up to your home phone line.)
