Scantronic lid tamper engineer reset

[Alan12]

Have a scantronic wired alarm system.
Was doing some DIY and unfortunately I made a mistake and undid the screws on the box. Now has a ‘lid tamper’ error displayed on panel. Think it is a 9651 model.
Reading online, it looks like this needs an engineer reset?

Do you have the engineer code ?

 

[Alan12]

tried the default engineer code, but that did not work. so no unfortunately i do not.

I could do a 1st stage reset (which would reset the engineer code to default factory setting), but would then have to re-install the system entirely i believe.

No first stage only resets the master and engineer code ….you will only have to re program those codes and time and date
20 ….engineer code
38 ….panel lid tamper ( which you have just found out )
51 ….time and date

Interesting, well that makes it a lot easier.

Am I right in saying that after the 1st stage reset, I also need to perform an engineer reset?

Out of interest - how does it retain all the system settings when I have to disconnect all power - both the battery and mains when doing a first stage reset?

It is retained in the non-volatile memory

It’s power up with reset pins shorted …1234 to stop , 07890 to get into engineering …change options as before ….replace lid 99 enter , now just reset user code ….job done

Thanks - I just did a "1st stage reset", all sorted.
Interestingly, when I follow the instructions, I still could not get into "installation mode", and the user code has not changed to default (1234). The default engineering/master code still does not seem to work (07890). So I'm not sure I did a full and proper 1st stage reset...but I was able to reset the error message which I was not able to do before, and the clock and date reset...anyway problem solved!
