Connect one end of the cable into a telephone jack at the wall and the other end into the back of the control panel. Connect to the RJ-11 jack on the controller marked "LINE."
Connect a filter between the wall jack and the wire if necessary. If you have broadband internet service on that be sure to connect a line filter between the wall jack and the alarm. The alarm will work on a line with Internet but not on a line which is part of a telephone exchange system--also known as a PBX system. You will need to have a separate line installed if the line has telephone extensions with extension numbers on it.
