In a few vicinities the Police refuse to dispatch if you have not registered your alarm system with them. Examples are Houston (and all of Harris County), Texas and Baltimore, Maryland.
In other places the Police may charge a fine if they respond to an alarm from your system before you have gotten a permit with them. The best way to find out the details is to call and ask your local Police Department or look on their website. Some areas allow a grace period when an alarm system is first installed.
