We had a powercut a few weeks ago and the outer wall alarm box has been flashing with a white light ever since. I have tried to reset the system but the keypad does not do anything when I punch in the code - it doesn't even beep when I press the number keys. I have tried turning it off and on again at the fuse box but the problem remains. The digital readout constantly has a 'U' with a peculiar symbol next to it. Any ideas how to stop the white light flashing on the outer box?

Cheers, Simon.

Hi Simon, It could be easy to sort out, give me a ring so I can tell you what to do, it will only cost you the cost of the phone call, But Please only ring between 6pm & 9pm only.
