Or a 16th Ed split load with one side of RCBOs. That works well too.

is there any other method? Eg a wall 'hush' switch?

If you mean Aico smoke alarms.yes there is.if not ignore the rest of the post

A triple switch that triggers, hush, and located about £30
The triple switch works only with the 160s range not the 140s
