over here "interlinked" would be a good extra keyword.

Bad idea. If the power is out, no alarm.
Power could be out due to an electrical fire.

Search for hardwired smoke alarm.
The word "hardwired" means they are powered from the
AC mains. (They also include a backup battery.)

MICC (Model International Criminal Court)?

First google hit. No idea what MICC may be for you.

If you refer to "Mineral Insulated Copper Cable", no. The mains may
still be out.

The main reason to have the detectors run from battery is precisely to
avoid failures due to failed mains.

Incidentally the laws of the state of Massachusetts requires hardwired
smoke detectors in all one and two family homes permitted (i.e.
constructed and/or renovated) post 1975, prior to sale or transfer of
the property.

I doubt any first-world fire code would allow the installation of
mains-only smoke detectors, they're going to be either battery only or
mains-powered with a battery backup.

Some more recent codes don't even want the user to be able to tamper
with the battery and the battery-powered units are to be sealed at the
factory.

We have a factory sealed unit in the house we moved into seven years
ago. It beeps when I burn the toast!
