Sorcerer, it's not unlikely that they'd be able to get the result electronically, the most heath Robinson setup would be a camera sending an image of the test output every day. Given that, there are therefore ways of making it simpler, having a light detector behind the bars on an lfd, as the bars darken the detector trips. You could track the entire country from one control room. Not sure how you replace the equivalent of the strips once triggered.
