Yes, it seems I need a heat detector. The doorway between our kitchen and dining room has a brick arch, and is too low to fit a fire door too - or any door, come to that.

I can't find a heat detector which is compatible with the 240v 9v backup smoke detectors I have already bought.

Is the answer to buy a fire alarm panel and connect a heat detector to that, and have two separate systems, or will that still not satisfy regs?

Or shall I just bite the bullet, fit a lintel and a firedoor and take the firedoor out again after Building Control have finished with me.

Every time I think I have got this job sussed it gets more complicated. Sad

Am posting this is a slightly different form in the alarms section as well.

Thanks JohnD

No, its just a kitchen added on to an existing house, but Building Control tell me that unless there is a fire door between the kitchen and the dining room (the present kitchen) they will expect to find a heat detector in the kitchen as well as the mains wired smoke alarms they have already told me will need installing...........

I needn't have worried. The interconnect facility on my Screwfix smoke alarms doesn't work Sad

(even though my wiring seems o.k., (and yes, I have bench tested them to make sure, much to my dog's delight

) so they are going back. I can then buy smoke alarm/ heat detector units which are known to be compatible.

Anyione suggest a good make - and tell me where to get them? (And don't mention Screwxxx! Lips Sealed

)

Thanks

Does there _have_ to be a fire rated door between a kitchen and a living room these days? I was planning to fit a glass door but I suspect they aren't classed as fire doors... [/quote]
Presumably there's a definition somewhere of what a fire door is? Or some sort of rating system that means when you buy a door you can tell whether it is classed as a fire door?

But unless the regs also insist on automatic closer devices, it's all a farce anyway. I have a door on my kitchen - it's open 99.99% of the time....

Aico look good, work well, and are actually realy cheap!

They also have a hush button which is useful Wink

All ground floor doors and kitchen doors have to have a closer on them now (not sure of the exact reg, but all new builds here have them).

They dont need to be the commercial top of the door type, just the chain in the hinge side of the door, or hinge closers.

Fire doors have a spec, and will also have an intumiscent strip around them. they have a coloured dowl in the door edge to tell the fire rating.
