S.T.
I have had the very same problem with ADT. My husband travels all week and mine went off in the middle of the night. Scared me to death and there I sat huddled up in my room thinking someone was breaking in.....no call from ADT. I finally called the police non emergency number and got the police to come and check things out for me. I later called ADT and they had some lame reason for not calling me. Something like I turned it off too soon. I let it blare for at least 10 minutes. I agree it is RIDICULOUS that they don't call you. What if someone had a gun to my head and made me turn it off real fast! I was steamed about it too! I was so scared and could not go back to sleep all night.
