anyone know where I can get the basic information on proper placement of smokies in resi?
Smoke alarms. Smoke alarms shall be installed in the following locations:
1. In each sleeping room.
2. Outside each seperate sleeping area in the immediate vicinity of the bedrooms.
3. On each additional story of the dwelling, including basements but not including crawl spaces and uninhabitable attics. In dwellings or dwelling units with split levels and without an intervening door between the adjacent levels, a smoke alarm installed on the upper level shall suffice for the adjacent lower level provided that the lower level is less than one full story below the upper level.
Does that mean "not on any AFCI circuit?" That would be an NEC violation, no?FrancisDoody said:
- Connecticut has a requirement that smoke detectors shall not be wired into the bedroom AFCI circuit.

A smoke detector is utilization equipment, right? :roll: Meaning it's installed at an outlet, right? :roll:

The problem with that concept is that residential projects are different in purpose from commercial.Jim W in Tampa said:I would prefer it left up to the person taking the risk,mr homeowner.
4) carbon monoxide on lowest level
I would think that most CO producers (gas furnace, gas water tank) are usually on the lowest level (basement).infinity said:4) carbon monoxide on lowest level
Why on the lowest level? If there is only one CO detector it should be outside the sleeping area. Most CO related deaths happen while the person is asleep.
I would think that most CO producers (gas furnace, gas water tank) are usually on the lowest level (basement).
Also CO is heavy and stays low. If a house has a stairway into a lower level in the garage, you always have to have a step up before the stairway down to block the CO from the cars from rolling into the lower level of the house or collecting in the bottom of the stairwell when the door into the house is closed.
The best spots for CO detection are:
in rooms with large gas burners like furnaces and water heaters
and also in common hallways in bedroom groupings.

Carbon Monoxide Detectors - UL Standard
"According to UL Standard 2034, home carbon monoxide detectors must sound a warning before carbon monoxide levels reach 100 parts per million over 90 minutes, 200 parts per million over 35 minutes or 400 parts per million over 15 minutes. The standard requires the alarm must sound before an average, heathy adult begins to experience symptoms of carbon monoxide poisoning. The warning provides time to evacuate the premises."
PLACEMENT OF CARBON MONOXIDE DETECTORS IMPORTANT
Proper placement of a carbon monoxide detector is important. If you are installing only one carbon monoxide detector, the Consumer Product Safety Commission (CPSC) recommends it be located near the sleeping area, where it can wake you if you are asleep. Additional detectors on every level and in every bedroom of a home provides extra protection.
Homeowners should remember not to install carbon monoxide detectors directly above or beside fuel-burning appliances, as appliances may emit a small amount of carbon monoxide upon start-up. A detector should not be placed within fifteen feet of heating or cooking appliances or in or near very humid areas such as bathrooms.
When considering where to place a carbon monoxide detector, keep in mind that although carbon monoxide is roughly the same weight as air (carbon monoxide's specific gravity is 0.9657, as stated by the EPA; the National Resource Council lists the specific gravity of air as one), it may be contained in warm air coming from combustion appliances such as home heating equipment. If this is the case, carbon monoxide will rise with the warmer air.
For this reason, the makers of First Alert (R), the leading brand in carbon monoxide detector technology, suggests mounting the detector on the ceiling. This also puts the detector out of the way of potential interference, such as pets or curious children.
Here are the requirements in Ohio. The following is our departments combination of our state code OBBC R313 and UL listing specs which are based mostly on requirements found in the Fire Alarm Code NFPA 72.stew said:anyone know where I can get the basic information on proper placement of smokies in resi?

I believe the requirement that garages be lower than the living space is to keep gasoline fumes, which are heavier than air, from entering the living areas.
Also, the car exhaust contains a great deal of water vapor which would affect its density.
