Smoke/heat alarms for barn conversion

[jfb]

I think I asked a while back about this but cant find the thread.

 

I'm wondering if my plan for alarms is acceptable. Its a small barn conversion (70m2 total) with an open plan downstairs (except for lobby/toilet) and 2 beds/bathroom/landing upstairs.

Looking at the plans below I am planning on a heat alarm  where the 'h' in kitchen is (downstairs - first image) and a smoke alarm in the landing at the top of the stairs in the second image. I am thinking that is sufficient - would that be correct?

 

Is there a minimum distance a heat alarm should be from a cooker?

Also - am i right in thinking it should be wired in 3 core and earth (1.5mm) radially on its own circuit?

Technically yes, but only your BCO can give you a final answer for your dwelling. We can only procrastinate I'm afraid.

I would install one on the edge of the living room ceiling tbh.

 

3c + E yes. Regular twin and earth from CU to 1st detector.

 

I'd be looking for 3m distance away from cooker / oven / kettle etc so as to not get nuisance alarms.
