It’s just the collector/enthusiast in me, but I wish they had the HS units with free-run options also. That way a collector/enthusiast could power it up w/o a SmartSync module/panel. But I’m glad Simplex found a way to integrate 520Hz in what seems to be the same or slightly larger footprint as the normal TrueAlert, unlike Wheelock/EST/Gentex who are using 4" speakers.
