How can I reset Alarm key pad - keeps beeping (Phone line)?
AT&T Tech was out to repair U-Verse - he had to troubleshoot phone line by disconnecting. Now, control panel keeps beeping with message "phone control." How do I reset the panel or security box.
It sounds like its looking for a telephone line. The alarm needs to see a telephone line, so the alarm panel has gone into line fault, because it monitors the telephone line. What company fitted alarm?????????
