Where should a carbon monoxide detector be installed in a 3 story house with 6 bedrooms upstairs.
Should it be installed up high or low or...?
 
Here's from a question and answer about CO Detectors:

Where should I install my Carbon Monoxide Alarm?

Install at least one CO Alarm near or in each separate sleeping area. For added protection, install an additional CO Alarm at least 15-20 feet away from the furnace or fuel burning heat sources. Also, locate CO Alarms at least 10 feet from sources of humidity like bathrooms and showers. In two story houses, install one CO Alarm on each level of the home. If you have a basement, install that CO Alarm at the top of the basement stairs.

Is there anywhere I shouldn't install my Carbon Monoxide Alarm?

DO NOT locate a CO Alarm in garages, kitchens, furnace rooms, or in any extremely dusty, dirty, humid, or greasy areas. Do not place units in direct sunlight, or areas subjected to temperature extremes. These include unconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, and porches. CO Alarms should not be located in outlets covered by curtains or other obstructions. Do not place in turbulent air-near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows. Blowing air may prevent CO from reaching the CO sensors.

Is one CO Alarm enough for my home? If not, how many should I have?

Install a CO Alarm on every level of your home. If you install only one CO Alarm in your home, locate it near or in your bedroom.

How high should I install my CO Alarm?

For ease of viewing you can locate the alarm about 5 feet off the floor. Carbon monoxide weighs about the same as air and distributes evenly throughout the room/house. Choose a location where the CO Alarm will stay clean and out of the way of children or pets. See your User's Manual for specific installation requirements.

Great info. I would personally say one per level at a minimum.
 
You want it mounted close to the furnace vents in bedrooms. My parents' house, for example, has the detectors mounted near the floor by the vents.
 
Note in Strongt's post the instructions to NOT place the unit near the furnace vents or fresh air intakes. Meshes with what I've seen elsewhere.

Building code in Minnesota is now at least one on each level of the home and there must be one within 10 feet of every bedroom. Any electrical or HVAC work is often the time this gets checked and brought into compliance.

I went with a combo smoke and CO unit. Home now has three combo units and three smoke only, all interconnected and meets current building code. Also have a CO unit that plugs in the wall with a readout of CO levels. Useful for tracking down some false alarms (had two combo units go bad near their 5 year expiration).
 
I got a CO detector with display, hoping it would show levels too low to alarm. (I run a wood stove and am high risk.) Piece of junk won't tell me, even though it knows. Think threshold is 25 ppm and it goes down to 10. Will tell a fireman though, somehow. Kiddie brand.

After I got it home I discovered it has a 7 year expiration. I won't buy one with bells and whistles again.

I would keep CO and smoke detectors separate. 9v batteries come in multipacks anyway, and you don't want to keep the "spare" kicking around a long time only to install in a lifesaving thingy.
 
At least one on each level.

We have a sprawling ranch, and on the main floor have one near the master bedroom suite and one near the guest bedrooms/office. On the lower level I have one near my wifes office, and one at the opposite end near the laundry room.

I also have one in the garage and one in my shop building. It never has gone off with a modern car, but on the occasion that I pull one of my Ford N's in the garage, if they idle for more than a few seconds it will set the alarm off. I sometimes work on a tractor with the exhaust vented outside-should the hose slip off the tailpipe (or leak back into the building) I'd want to know as quickly as possible.

We also have propane gas detectors on the lower level, water sensors on the lower level and fire/smoke alarms in the house, garage and shop building.
 
CO detectors all will generally expire in 5-10 years from being activated. Smokes should be replaced every 10 years.

The main reason for the combo units is they provide an interconnect - if one goes off, they all do. With three full levels, we'd never hear the one in the basement if we were upstairs. Building code here requires the interconnect + hardwire electrical + battery backup.
 
Yeah, I keep forgetting that I need to replace mine. 7 years comes quickly... I have to wonder if that is a bad thing--I've had one CO dectector for the last 15 years (more? bought when they got cheap, I was renting in college--and it don't take a college degree to know how important these are!) and these days it just lives in the basement. Might not hear it if it goes off, but the upstairs detector would catch that anyhow. Old units can be moved to non-sleeping quarters (garage, etc).

The downside to interconnect is, set one off from cooking, and the whole house suffers...
