Smoke locations?

[Sberry]

I am doing a rewire of a mod that was moved. 1 floor no basement, what is the general location of the smokes and how many is typical in this 3 bedroom 1 bath?

One in each bedroom, one "in the hallway" outside the bedrooms.

Are you doing CO as well? If so we do smoke/CO combos for the hallway

It hadnt even really occurred to me I forgot them and going to throw a roll of 3 cond back on the truck, good to remind me about CO too.. I cant recall ever seeing them in bedrooms but makes sense being interconnected.

Most of the ceiling is still up, I pulled all new for outlets and chased down all the switch loops and salvaged most of it above. Can they go on the walls?

 

[marmathsen]

Walls are no problem they just need to be within 12" of the ceiling.

You don’t need a CO in every bedroom. One in the hallway is sufficient.

That falls into the requirements of your local jurisdiction. We don't need them in furnace rooms here in Washington but we have a new requirement of a heat detector in attached garages.

Installing and maintaining smoke alarms - NFPA

NFPA says installing your home smoke alarms correctly - and making sure they are in working order - is an important step to making your home and family safer from fire.

But not within 4" of the ceiling or in a corner.

Does anyone know what document is being used for enforcement most broadly in the country? I know it isn’t NEC. Some other NFPA publication?

In my State, it is the State Fire Marshal's office that dictates the smoke alarms.

I think most states have adopted the IRC in some form or another. R314 for smoke alarms, R315 for CO's.

Ours has this, among other things:

R314.3.3 Specific Location Requirements
Extract from NFPA 72 Section 29.8.3.4 Specific Location Requirements.*
This extract has been provided by NFPA as amended by the Office of the State Fire Marshal and adopted by reference as follows:
