Smoke detectors, which should you get ?

I'm starting to look at what smoke detectors to get for our new home build, and can see there's three types, smoke, photo electric and ionisation.

There's good things with them all, but which ones to get ?

I need two for my home build, so they need to be 240v with 9v backup, but which type ?

One is down the hallway, and one is to be located near the kitchen.

ionisation is very sensitive to smoke so don't use this type near the kitchen, save it for the bedrooms.
Get one that has a mute switch for those times you burn the toast

I don't know what kind we're getting but we're getting them connected to our home alarm system which I'm really happy about. I always have paranoid fears when on holidays that I'll come home to a burned wreck!!
