Alarm malfunction

user_aog9o0 Thank you so much for reaching out for help with your Xfinity home system not working. I have the Xfinity home security and depend on it when I am away from home, so we appreciate you reaching out for help. 5 years is a long time for a malfunction to pop up from the installation. Could you tell us a little more about what is happening, so we can better assist?
