Please note. the alarm panel is not the keypad. The alarm panel is the metal box that is usually installed in a hidden location in the house such as a cupboard.
 
Please see the image on the left that lists the alarm panels that are compatible with Olarm.
 
The IDS 806. X16 and X64 panels require a separate adaptor board.
