A master electrician told me my alarm wire loops were sloppy and I should stop coiling them like extension cords.
He said the induced voltage from tight coils was causing false triggers on my harderwired zones, and after I switched to figure-8 bundles I have not had a single nuisance trip in 6 months.

Classic case of blaming the loops instead of admit you messed the crimp.

dude said induced voltage from tight coils" - yeah that's a real thing but its a pretty minor effect in low voltage alarm wire. unless youre running like 100 wraps of wire in a 2 inch loop its not gonna cause false triggers on hardwired zones. sounds more like you had a loose connection or bad ground somewhere and the figure-8 just moved the wire enough to fix it by accident.

Back when I was doing installs for ADT in '04, I had a zone 2 on a front door that would ghost trip every time a garage door opener kicked on a few feet away. I must have checked the coil diameter five times but it was only like 3 wraps for the service loop. @ivan774 is probably right though, I ended up re-terminating that screw terminal and the problem vanished. Loop shape was just a coincidence.
