Then you either give him a lookup table with ONs and OFFs in the same
layout
as the DIPs on the detectors like (assuming ON is UP):
1 ON
OFF OFF
-----------------------------
2 ON
OFF OFF
-----------------------------
3 ON ON
-----------------------------
4 ON
OFF OFF
-----------------------------
OR you spend half-an-hour one evening setting all the dip switches on the
detectors to different, then writing in magic-marker the number in
'normal'
inside the cover, so Laddo just has to copy the 'normal' number off the
detector onto the plan or location list as he installs each one.
OR you spend an hour one evening, setting all the dip switches in the
detectors, writing the number in magic-marker inside the cover, making the
list of locations or marked up plan, so all Laddo has to do is put
detector
318 in location 318 on the plan.

One engineer spent all day doing this for him on one job, but when he went
back to commission it he still found detectors in the wrong place.
With the materials mostly being delivered direct to site in a big box, it's
not really practical to take all the heads out and set them up for him. I
just wish I could make him understand that it can only be ON (1) or OFF (0)
and that the base number is two. But this is where he gets confused. He
says that "If the base number is 2, then why is there only zero's and
one's".
Aaaarrrrggghhhh !!!!
