mains flashing code?

The ‘Mains’ Lamp:
 
The ‘Mains’ lamp is on when mains power is applied.  After a mains failure of more than 12 minutes, the ‘Mains’ light flashes until mains power is restored and an arm/disarm cycle is completed.  The ‘Mains’ lamp also flashes to indicate a low battery condition.  When the battery is restored to full charge and an arm/disarm cycle is completed, the ‘Mains’ lamp stops flashing.

So there's three possible causes:

no AC/ adapter faulty,

Panel faulty or not charging the battery,

Faulty battery or leads/connections.

A multimeter can assist you if you have one and of course the ability to use it.
