CO Detector Location

[Rock86]

This may get rejected because it is not NEC related...

NYS Fire code states that a CO detector (where required) needs to be 10ft from the entrance to the sleeping area in dwelling units. Does anyone know why 10ft is the magic number when a CO detector has better range than 10ft? I keep running into situations where I have a hall way with multiple CO detectors down a corridor because the bedroom doors are greater than 20ft apart.

It's a local amendment. My state required a CO detector within 15' of the entrance to a bedroom.

I can only speculate as to why. If CO is traveling down the corridor toward the bedrooms, would you want to know sooner or later about the threat?

have a question does anyone have a code for smoke locations if i have a 12'' header between living room and entry that ill need one in both rooms cant remember the nfpa code

It could be NFPA 72 chapter 17. 7.3.... or chapter 29.

Depends on height of ceiling. The beam's affect on smoke flow is reduced as ceiling height increases, but I'd ask your local fire department's prevention office.

Check the instructions as well as the residential code.

Per NFPA 72, a separate detector would be required in each area if the beam depth is greater than 10% of the floor to ceiling height in the beam pocket.

Sleeping area means the entire corridor, not each room. One detector at the opening to the hallway covers the entire area.

That's a great interpretation. thank you!

You're welcome.

Besides one in each bedroom, also one between the bedrooms and the rest of the house.

I looked back at the code... and the definition of a sleeping area is "a room or space that can be used, either on an occasional or permanent basis, for sleeping." I now don't think I can agree that the corridor can be considered the sleeping area.

No, the doorway to the corridor is between the sleeping area and the rest of the house.

I am pretty sure that CO detectors don't have range; they detect when CO molecules pass through them.

You want the alarm to sound close to the sleeping areas where people are most vulnerable. Some areas only require one CO.
