    How to Diagnose slow flashing (1 sec on, 1 sec off) yellow LED D7112 Panel

    Issue

    D7112 Panel battery will not hold a charge.

    Solution

    A slow flashing (1 sec on, 1 sec off) yellow LED with the green CPU LED off indicates a power supply overload condition.  The panel detects the battery as missing and the power supply cannot meet the power demand of the devices on the panel. The panel is shut down.
