Hi all I have recently moved into a new home .Last night we had a power cut and the alarm which we didn’t even realise was still connected went off and I couldn’t get it to stop until the power came back on.Could someone please advise me if there is a way I can permanently disconnect the alarm so it can never go off again .not sure if there is a backup battery that needs disconnecting as well as the mains power .The alarm is an omega 5 it’s has a keypad and a key .many thanks in advance
