Ours are fed from their own MCB in the CU via red triple & earth that

fed from a lighting MCB so it's "obvious" if that circuit is off.
However all the alarms have "mains ok" LED which is clearly visble at
night and observable by day.

I also attached a bulkhead emergency light to the circuit, halfway up the
stairs. Useful in a power cut, and it's obvious when the circuit has
tripped.


I also have a non-maintained emergency light in my hallway - originally
a fluorescent tube type but replaced a few years back with a LED
version. Although only 3 or 4W the light from the LEDs is enough to
illuminate much of the rooms off the hallway in the event of power cut
at night.
