Currently we are building a floor plan that has two combo alarms the living room space. On one side of the living room there’s a master bedroom entry, the other side is a guest bedroom entry space. What are the dimensions for a combo alarm to be installed between a living space and a bedroom space? Can we put one alarm in the middle of the living space and split the spacing between the two bedroom spaces?
One outside each bedroom.
Suggest you install a stand alone CO near the gas fired equipment.

Hello Elliot,
Milt Warner has given you very good accurate information. It is best practice to follow the manufactures installation instructions.
From my experience as a Firefighter/Paramedic and Fire Officer if you to follow cda cda's suggestion you will have many false activations. Gas fired appliances in normal operation produce small amounts of carbon monoxide. If mounted to near the appliance and how the sentativity of the co detector is set it may produce a false activation. Remember the best practice follow the manufactures installation instructions. thanks
Lawrence:
Thanks. I don't know where that idea came from to place CO alarms near gas fired equipment. Good accurate information should be disseminated to the public from the trusted public agencies. All I can say is "a little common sense goes a long ways."
Here is quick overview that "a little common sense goes a long ways."

I think people don't really read the manufactures instructions and figure that the closer the detector is to s possible co scource the more efficient it will be. I think cda cda got his suggestion from. There needs to be more Pub Ed on where to install co detectors.

We recommend choosing carbon monoxide alarms that have the most accurate sensing technology available. Carbon monoxide poisoning is the leading cause of accidental poisoning deaths in America. (Centers for Disease Control) At a minimum, industry experts recommend a CO alarm be installed on each level of the home--ideally on any level with fuel burning appliances and outside of sleeping areas. Additional CO alarms are recommended 5-20 feet from sources of CO such as a furnace, water heater or fireplace. Alarms can alert you to a problems only after smoke or carbon monoxide reach their sensors. Choose locations free of obstructions, where the alarm will stay clean and protected from adverse environmental conditions. Do not place the unit in dead air spaces or next to a window or door.
Ok no closer than five feet?
Suggest you install a stand alone CO near the gas fired equipment.
I guess near means less than five feet??
OHHH I am not an engineer, so you can discount my reply if you want, and I cannot do math.
Hi all:
The previous advice presented to Exchange was not documented in any manufacturers installation manual?
Take or leave it..
Suggested carbon monoxide alarm installation locations seem to vary widely, by manufacturer. Manufacturers’ recommendations sometimes differ based on research conducted with each company’s specific detectors. Therefore, be sure to read the provided installation manual for each model of CO detector before installation.
As Lawrence says: "Gas fired appliances in normal operation produce small amounts of carbon monoxide. "
Cda's jurisdiction must be well prepared to handle false activation of the alarms with services by their Paramedics and possible unnecessary transport to hospitals to rule out the potential of possible carbon monoxide poisoning of the residents.
I have a story I would like to tell:
My former jurisdiction had an incident where the local fire department had located a carbon monoxide (CO) monitor near the gas cooking equipment in a nursing home kitchen. The alarm activated and the fire department and Paramedic took the alarm as a potential CO poisoning of the 20 kitchen and serving staff. They were all transported to the hospital and evaluated at the facility's expensive. The kitchen was condemned from use with no meals for the residents until the CO levels were within acceptable limits. Estimated cost for catered meals for 120 residents for 3 days $3,600.00. The outcome was none of the staff showed above average ambient levels of carbon monoxide in their blood. The bill for emergency room was about $20,000.00. An air quality specialist was retained by the facility to evaluate the ambient CO levels of the kitchen staff work areas under normal operation and dining room and it was found the levels were within acceptable limits. The evaluation tested the exhaust hoods" air flow and found they met or exceeded NFPA 96 requirement. Testing estimated at $5,000 - $6,000.00.
It was later found out the fire department inspector after review of his report, he had placed the CO monitor under hood over the gas cooking ranges. I will leave the conclusion up to you what the inspector's thoughts were to do that in consideration of the advice given.
Respectfully,
Milt Werner
Ok Milt you did the research. I just replaced our out of date smoke alarms and CO detectors with Kidde combination smoke alarm/CO detectors the installation instructions had the 5 to 12' instructions guess as you said instructions may vary as manfacture.
As to your CO story either the Fire Inspector did not read the manufactures installation instructions or they did not include mounting instructions or he did not read NFPA 72 and very last possibility sadly he was incompetent.

- CO alarms should be mounted in or near bedrooms and living areas. It is recommended that you install a Kidde CO alarm on each level of your home
Locations To Avoid when installing the CO alarms in the above recommended locations.
- Do not install in kitchens, garages or furnace rooms that may expose the sensor to substances that could damage or contaminate it.
- Do not install within 5 ft. of heating or cooking appliances. (Kidde recommends 15 ft. to prevent nuisance alarms).

Yes I know that Milt Warner advised me of my eror earlier to day. The 12' comment resulted from the discussion earlier. As Milt stated some manufactures advice different mounting distances.

The carbon monoxide detector requirements are covered in NFPA 720 chapter 9. Combination carbon monoxide/smoke alarms are covered under this section. Also, NFPA 720 is adopted by reference in the International Residential Code. Both the Residential Code and 720 state that carbon monoxide detectors must be installed outside of bedrooms in "the immediate vicinity." The annex a of 720 gives non-binding information that 10' or less to a bedroom door is probably acceptable to meet the "immediate vicinity" requirement (unless the manufacturer states differently, of course). 720 states that the manufacturer's instructions shall be followed (article 9.3.2. )

Hi all:
I read the IRC requirements and there is always more to add. I reread the original post and it seems to me it was dealing with carbon monoxide alarms. Somehow the discussion has moved to unrelated carbon monoxide detection system requirements.
Respectfully,
Milt Werner
Fair enough. In my opinion, if you want guidance on the placement of combination smoke detector and carbon monoxide alarms then you need to look in both NFPA 72 (smoke detectors and alarms - chapter 29) and NFPA 720 (carbon monoxide detectors and alarms -chapter 9). This is for house holds. I am sure Mr. Werner will you borrow his copy of UL 2034 if you need it. (Joking, of course....that standard costs between $798 and $1990)
Regards,
Kevin
Great comment - Fair enough for me too. I understand the problems. That is why we depend on the certification organizations with full trust or confidence that the devices and their installation and use instructions comply those UL standards.
Respectfully,
Milt
Hi Elliot:
Here is a installation instructions from a major manufacture of smoke alarms.
"Put CO/smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is more than 30 feet (9.1 m) long."
I recommend you get current copy of NFPA 72 and review it for your application, and consult your local codes on the issue.
Respectfully,
Milt Werner
