I've recently been doing some redecoration which necessitated the
removal of a PIR.
When I put it back I seemed to have damaged it somehow.
The alarm panel is now showing a constant tamper fault light which I
can't deactivate.

Usually just removing and replacing the cover does the trick but this
time it's with no effect.
I don't know how the tamper sensor works so can't work out what else
to try with the PIR itself.

The system is, quite an old, Scantronic 4700 system with wireless
PIRs.

I don't have the engineer code for this box only the general activate/
deactivate code.

Can I replace the PIR using something generic? I'd rather not have to
replace the entire system as this one does the job very well normally.

Any alarm techies here who can advise?
