Well I think they have built the cupboard around the unit...it was a ballache to get the cover off!

I've found which spur it's on so can safely kill mains when replacing battery. Presume they have some flash memory to maintain setting?

Hopefully I can do it tomorrow and report back

Yes they have a Non Volatile Memory chip that keeps a hold on crucial information i.e codes. You will need to re enter in the time and date.

Cheers both, appreciate the advice/instructions.

Ordered a replacement battery for £15. The one place that wanted to come and "service" it were quoting me minimum of £250 for an hr of their time. Eeesh!

Good job you came onto here then!

Good news!

Error codes cleared and can arm the system again

Only issue is date and time on the keypads have reset and I suspect I can't change them without the operators code.

Re your anti tamper switch, it's missing.

Look at the metal 'shelf' below the transformer, that is where your a/t switch should be.

An oblong piece of metal slides in and through to the back of the panel to the wall, the front of it would have the tamper switch mounted, protecting the panel lid at the same time.

The twin core cable connects to this tamper switch, or would if it was not missing.
