Most houses here are small vacation homes. They have two bedrooms upstairs with a balcony over a great room with a catheral cieling. No basement. Master bed room is on 1st floor off kitchen. Where are they suppose to put the smoke alarm? The home is only 38' x 20'. If you put the smoke alarm 10' away from kitchen it ends up on the far side of the house from the bedroom by the gas fireplace. And you would have to put it outside on the deck to get 20' from the stove.
 
Installing a photoelectric smoke alarm instead of an ionization smoke alarm may be one approach to reducing nuisance alarms.

photoelectric smoke alarms are less prone to nuisance alarms in the kitchen area than ionization smoke alarms

From the `06 IRC, Section R313.2 - Smoke Alarms, # 2: "outside

each separate sleeping area in the immediate vicinity of the bedrooms".

Installation of an approved type Smoke Alarm may be a trial & error

process in your case **Rick**, to find the most workable & compliant

location.

Without seeing a floor plan hard to give a good answer

With that said one in each bedroom

One "somewhere" outside

Not sure about your distances

But would say technically a smoke alarm covers 15 feet on each side

So as stated above maybe trail and error

I would not worry to much about the upstairs one

Does the upstairs bedrooms have doors to them??

And the one for the master bedroom to me can be max fifteen feet from the door to the bedroom

This is what bugs me about the requirements, say you had a very large house the way ideas the code you only need one on say the first level, if it did not have any bedrooms.

Does a one require them to be spaced for coverage, in that there would be a few detectors on that first level with very large sq ft
 
I think the whole idea for alarms is wake people in the bedrooms. So what's more important, the alarm close to the bedroom in the kitchen or 25' away on the other end of this house.

In your case near the bedroom door

But does no hood if cooking constantly sets it off

So I would look where I could put it up to fifteen feet away from the bedroom door in order to cut down on false alarms and the home owner just taking it down
 
Maybe on the upstairs put them on the wall above the bedroom doors, installed properly.

That should get them as far from the kitchen as possible, plus they are not on the ceiling
 
Code still allows the SD to be placed on the wall, would that help? I would'nt think steam from cooking in the kitchen would set the alarm off if mounted on the wall. In my home the SD would go off due to a header trapping steam, so the wall mount idea may work.

I remeber something about 20' from cooking appliance.It is in the Manufactures installation instructions or NFPA 72 that is referenced by the code.
 
2007 NFPA 72 11.8.3.5(4) Smoke alarms and smoke detectors installed within a 6.1m (20 ft) horizontal path of a cooking appliance shall be equiped with an alarm-silecing means or be of the photoelectric type.
