Or on a separate circuit, linked to a visible non-maintained emergency

needed. If the circuit fails, the light comes on and you get a visual
indication.

Having one of those on the lighting circuit that illuminates the CU is a
good plan as well I think. That way you are not groping in the dark to
reset a MCB or RCD.
