The must be on the same circuit and generally are put on a lighting
circuit (ground floor preferred) so that circuit trip is immediately
apparent (evening/night at least).
If you do that then there should be a means of isolating the smokes
whilst still leaving the lights powered up.
Is there a recommended way? I presume it should not be *too* easy?
Emergency key type test switch or just an out of the way normal isolator?
For a RCD protected circuit I would suggest a double pole key switch. For a
non RCD circuit (16th edition) an unswitched fused spur would be fine on a
TN supply.
