Thanks, I now understand - I must have missed that part of the installation manual. It shouldn't be too hard for me to re-mount it with the rear tamper also secured.

 

I also tried the other position on the 3-pin header as you suggest and this appears to resolve the problem - first I successfully used a jumper and then the actual switch. No more 'panel-lid tamper' or 'box-lid tamper' so thanks! I'm not sure what the purpose of the left-most pin is on the header in that case as it seems not to require connecting to anything, I must have simply plugged the header onto the wrong pair of pins at some point. When I initially powered up I did hold down the factory default button which as you describe did result in a number of tampers - good to know that's normal.

 

One last question - when removing the cover the tamper goes off and the buzzer on the RKP sounds, however my siren does not. Is this the default behaviour for tampers and can it be configured for the siren to activate as well? The siren works fine when using the 'test siren' feature or if I arm the system then deliberately trip one of the PIRs so it seems to be wired in OK, I haven't tested what happens if I activate the tamper on a PIR or the RKP.

 

Thanks very much for your help!

It would be a pain having bells go off everytime a tamper goes 

 

You could if you really want to add aaster blaster in the house haha select an output linked to the tamper , have an output that disables it when in engineer mode 

 

But you might get headache 

That's great, thanks for clarifying how the tamper works!
