Ran trim resistors in parallel for 8 years, series fixed my false alarms

I used to wire my EOL resistors in parallel because that's how my first boss taught me. After 11 false alarms across 3 sites in Austin, I tested series and suddenly the zones read clean every time. Anyone else got a wiring habit that took a disaster to break?

Took me 14 years and a burned out panel to finally trust anything over parallel, but hey, at least I get to blame my first boss instead of my wiring skills.
