Hi I wonder if someone could help me please.I have a Veritas R8 with 5 zones 2 keypads,2 panic Buttons.We went away for the weekend came home electric Had triped alarm had gone over to battery and flattened both alarm panel and bell box, I turned electric back on alarm powered up and recharged but both key pads won't do anything every button you press has the same tone it seems to have locked out.The battery seems ok because if I disconnect from mains it lasts ages.Is it time for a new panel? Thanks Guys Gary
