Need help fixing my Optima XM6 alarm system?

Recently had a power cut in my area therefore was without electricity for 1.5 days. During the second day of the powercut my box outside started alarming with the blue light flashing, as the battery must have started to run out the noise got less eventually died out but the blue light remains flashing. On my optima box where it says zones 1-4, zones 2 and 3 are red and where it says Power the square is red also. When i press the reset button or any of the other buttons nothing happens. Since the electricity is back on my box outside the house just keeps flashing blue. Any ideas on how to regain control of my alram so i can stop the blue light flashing and actually set my alarm on?

Manys thanks for any help provided
