Re: Electric smoke detectors
Yes
You have to check with each building department to see what their requirements are.
Some smokes just on every floor, some on every floor and inside and ouside of each sleeping area.

Re: Electric smoke detectors
IN WI.
For a single family:
You need one in every bedroom, one outside of every bedroom with-in the vicinity of the bedroom, and one per floor.
The average 3 bedroom requires 6-7 smokes all interconnected with battery back-up.
If you type your state into google and go to your state's website your likely to be able to find there requirements.
If your dealing with a multi-family or other applications check with the local fire and electrical inspector. I just finished a 8-bedroom assisted living and I was required to install 15 smoke detectors 120v interconnected. A fire system with an additional 16 smokes, 4 heats, flow indicator, tamper switch, 2 alarms. And normally we feed our fire alarms with romex, but this inspector required MC cable. Things vary from town, to village, to city, to state.

Re: Electric smoke detectors
Bogman: Unless your state has amended your building code, each level and inside and directly outside of each sleeping room. As Mike suggested, a simple call to the building department will address your concerns.
Mike: This is the exact requirement out of the IRC (section R317). I like your suggestion of consulting the building department however, its a very good idea.

Re: Electric smoke detectors
Binnie ,florida is exactly the same as what you described.There are a few other factors like highest point and 3 feet from AC registers and fans or bathrooms.Local rules do change so anyone wiring in a new area would be wise to check it out first.

Re: Electric smoke detectors
1 in every bedroom and within 10 feet of every bedroom. which means if a bedroom is directly off the kitchen than a photelectric smoke needs to be installed in the kitchen within 10 feet of the bedroom.

Re: Electric smoke detectors
within 10 feet of every bedroom
does this mean within 10 feet of its door or closes wall ?

Re: Electric smoke detectors
An asside to the earlier reference to the IRC.
NFPA 72 11.5.1.1 One-and Two Family Dwelling Units
(1) In all sleeping rooms
exception: Smoke alarms shall not be required in sleeping rooms in existing one-and two family dwelling units.
(2) Outside of each seperate sleeping area, in the immediate vicinity of the sleeping rooms.
(3) On each level of the dwelling unit, including basements.
The detector in #2 could be in a hallway or any wall in the immediate vicinity of the room per this code.
The annex diagram shows "one" detector in a hallway serving three BR's.
This is another example of where electricians can't just live out of one book any longer

Re: Electric smoke detectors
Jim, I know where you're coming from and sympathize. The good side of this is that the industry is mandating better and broader trained individuals. I think this will only help in the future electricians (if that is what they will be called) demanding and getting better wages.
Technology will not allow us to fall behind, and this may include having as much reference material (code books, tech books, spec standards, etc...) as a MD or Lawyer would have.

Re: Electric smoke detectors
I know a name changed helped the garbage men get more respect.
hmmmm how about, wiring system engineers
That might get me an extra few bucks.
We use to call them helpers now we call them installers.
In Florida we stopped building porches,found we could charge more for a lanai

Re: Electric smoke detectors
We've got a fire marshall in a small town here in Fla, that requires resi-type smoke detectors (in absence of a fire alarm system) in all his commercial buildings.
Is there a specific reference to this in any NFPA publication?
During the design stage of these projects (mostly design/build) he can't say for sure how many he will require. But he comes out during the rough in and points out where he wants them.

Re: Electric smoke detectors
D and O the Fire Marshals requirements are a different story, but is usually governed by NFPA 72.
Jim, you won't be able to expect anything more than you get right now without the tools or knowledge.
