Accenta Alarm Strobe flashing?

Hi

I have an Accenta G3 which is about 10 years old. We had a power trip the other day and now the strobe won't stop flashing.

I cut all power to the house and noticed that the battery back up wasn't working, so I thought that may be the problem.

Bizarrely the alarm fitter hid my panel box under the floorboards in the spare room.

So after two days, I've eventually found it. I have now replaced the battery, which was a nice easy job, however the strobe is still flashing.

Could you offer some advice please, do you think it may need a new bell box ?


Many Thanks

Andy
