When my installer switched to API from our original monitoring company we had problems from the start. When we accidentally triggered the intruder alarm and then disarmed we never got a call. I called them and they will not call if the intruder alarm is cancelled by the owner. I explained that if there was an intruder alarm at night l would first disable the alarm/siren so I could investigate. They are not set up to do this. Instead they started calling us when the had an indication of an opening. I could not resolve situation, they seemed to be somewhat dense. I moved to another company that ensures each customers needs are met.
