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

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!

Apologies I must be misunderstanding - which part is the keyhole plastic? Do you mean the empty keyhole-shaped cutout on the rear roughly in the area of the front cover tamper? Nothing is fitted to this I assume it is where a rear tamper would be if there was one. As I've fitted to the wall I would have to remove the unit to investigate this further. I will use a jumper to short the header - I assume this should be the left and centre pin as this is where the tamper switch is connected? I have been 'resetting' by logging in with the engineer code and logging out again on the RKP (this was succesful in clearing the 'box lid tamper' I saw previously, as well as various other tamper alerts that occurred when I first powered on the system) is there any other procedure I should follow instead? Thanks for your help!

The only tamper switch I can see is the front cover tamper, so unless I'm missing something there's no back tamper - I can see no evidence of a tamper switch between the unit and the wall and there is no wiring for one.

The white lead is connected to the leftmost pair of pins on the 3pin header (item 20 in the manual). I don't think there's a back tamper fitted, just the switch for the front cover bolt. I've included a picture of this. I assume the firmware is printed on the sticker on the main board - this reads LS1 V4.01.03.

I have installed a Premier Elite 24 system and have programmed the zones as required, however I cannot get rid of the warning 'Panel Lid Tamper' on the system. The microswitch inside the control panel is closed (cover bolt is in place). If I remove the cover bolt I get 'Box Lid Tamper' in addition to the 'Panel Lid Tamper' which seems to be distinct. I can't find any reference to 'Panel Lid Tamper' in the PE Manual, although 'Box Lid Tamper' is referenced in the list of possible log events. I feel like I must be missing something here... if anyone can offer any advice I would be grateful. Thanks!
