My alarm was working ok. Had mains off for 1 hour to fix an electric shower. Turned on mains again. No red light in top left hand corner of keypad and unable to set alarm. Buttons light up ok when pressed and sensors red lights on ok. Someone suggested new battery. New battery fitted but still same. Anyone help please.

No name. thanks but have already gone through all the resetting procedures.
gts. I knew that but in this house there is no separate shower feed switch fitted. Had no choice but to switch of all. Are there fuses inside the alarm boxes?
