Accenta 8 post powercut displaying zone alarms?

Hi, after a power cut last night when the alarm was not set the alarm panels are showing up all zones except the front door when I try to set it. Tried reseting it to no avail. Only had it serviced four months ago and a new battery fitted. the PIRS are not showing up (flashing when I move in front of them). Any ideas what could be the problem? I thought it may have blown a fuse?
