Another thing could be to fit a battery powered mains failure alarm on
the same circuit as the smokes....

In any case, i have the house alarm and CCTV on the same RCBO as the
smokes.

The smokes are also wired in as a 24 hour zone on the alarm panel and
ditto for the CO detectors.

So when there is a power cut. The alarm keypads sound internally and I
get an email message from the alarm panel.

I have the smokes on the same circuit as the non-maintainmed emergency
lights. Obvious when the circuit trips.
