Ran 4 piezo sirens on one zone after a tip from an old tech in Reno, and every one of them fires clean

Kept chasing false alarms on a 3 siren garage circuit in Reno for 2 weeks, so I switched to running each piezo on its own 4 wire home run with 22 gauge and a single 1k resistor at the panel, and zero falses since March, has anyone tried the same trick with dual tech motions?
