The alarm went off the other day without it being set. I typed in my code to stop it and since then the display has UU. The bottom portion of the UU is flashing.
I looked through the manual but there is no description of this error, any idea folks?
Usual caveats about delving inside panels - if you are unsure - call in an engineer.
Disconnect the battery inside the panel.
Remove the fuse inside the panel.
Then reconnect.

Thanks for the help, how do I power it down? I bought the house with the alarm already installed and it seems to be hardwired somewhere as there are no visible wires etc for it.

Not heard of it either. Power down and power up to see if it clears it.
