So these have a little screw holding board in I think, you could take pic, remove 12v tape up and in turn each one tape up separately

 

Then take board out only and swap over with other 

 

Some might say upgrade the pirs anyway and scrap it ......

I'd be happier just buying a new PIR, I got the system fitted 15 years ago, so do I need to put in the engineer code, then turn off the 240 supply then change PIR?

to be fair at 15 yrs id be wanting to replace all. Unless ur still on your Nokia 6110 etc
