Requirements for a small kitchen in non domestic situation.

If you can post a picture of the alarm panel someone would be able to help in what's needed with a head swap and commissioning etc.

As for the wiring, same as any other job.

That looks Apollo/Alarmsense, which is a quirky 2 wire system.
I'd agree that the fire alarm will (should) already be maintained by someone- make that bit their problem. It's a simple job for them.
EDIT starting to wonder if it's XP95 addressable - definitely don't touch!

I think he has just plucked that from the internet.

LS0H cables should not be necessary, especially if the existing cables are PVC, unless specified by the local authority for this type of building.

FP/MICC would be th requirement here, not sure if there is a LSOH/LSF variant of FP, or its already LSOH/LSF by construction. Clause 26.2 refers.

the fire detector head twists off, leaving the wiring intact in the base. replace with same make, but heat rise. or, as someone has said before, get the Fire Alarm guys to do it. then there's no comeback biting your arse if the brown stuff hits the fan.

I think OP was referring to the general electrical wiring, as he is not planning to alter the fire alarm wiring.
