It would help if you'd tell us what country you are in. Crossfire security systems vary by region. You are being answered assuming you are in the USA - you show no location on your profile or posts - how are we supposed to know how to answer?
Additionally, you may have an aftermarket accessory alarm (probably not, but if so, you won't get an accurate answer here!)
