I was about to ask what made it the safe side - but it's that if you actually ground a ground wire, it's no big deal. Grounding a hot wire is a big deal.
Not that there are true "switch" options for the high amp stuff - using a solenoid. Personally, I'd be inclined to tie them all together if you're still getting parasitic draw from the various detectors.
Having everything ready on a toggle switch is very convenient, but it is another electronic component to fail.
