There are 3 bedrooms. One is separated from the other two by the main room of a kitchen and dining or living room. The 2 bedrooms together on the other side have a common hall, smoke, smoke and CO2. The bedroom by itself has a smoke in the bedroom. From that smoke by the time you cross the main living area until you get to the common hall where the other bedrooms are is over twenty feet. The question is should another detector (CO2) be installed in the living room. I thought there was something in the building code or manufacturers guide about not more than 20 feet and outside each bedroom. Thanks
 
It sounds like another is needed from your description. There should be one between each bedroom and non-bedroom areas.
 
If you can't locate the common area smoke equidistant and within 20 ft of each bedroom, you'll need to add one. The point of this is all about early detection. If a fire starts outside a bedroom with a closed door, it would take a very long time, when the fire is roaring, to trigger the smoke detector in the bedroom.

You don't need a CO detector within 20ft of a bedroom, just one at each floor level.

I don't think so. The co detector needs to be outside each sleeping area, I believe. A smoke detector is needed on each floor if no bedrooms are around

The op needs a smoke and a co detector in the hall.. we use a combo sd/co detector.

It may vary state to state

If the bedroom is located directly off the living room, then yes, there should be a smoke alarm in the living room by the door to the bedroom. You could make it a combination smoke/CO alarm, but definitely a smoke alarm, NOT just a CO alarm.

Our state code requires a co detector on each floor and within 20' of a bedroom.

For what it's worth, from NJ:

 Smoke alarm(s) must be installed on each level of the dwelling, including the basement, outside of each separate sleeping area in the immediate vicinity of the bedroom. Smoke alarms may be placed on the ceiling or within 12 inches of the ceiling on the wall.

 Section 915 of the building subcode and Section R315 of the one- and two-family dwelling subcode require that carbon monoxide alarms be installed in the immediate vicinity of each sleeping area when the building contains a fuel burning appliance or has an attached garage. Carbon monoxide alarms may be placed anywhere on the ceiling or the wall.
 
Every municipality is independent with CO detector placement.

Some here require CO detector within 15 ft of any bedroom (per mfg recommendation of 30 ft diameter detection area.

Some require CO detector "adjacent to" sleeping "area" and there are no footage specs.

Some require CO detector "in the approach to" bedrooms. Basically at the beginning of a hallway leading to any number of bedrooms

All of these variations make the assumption that there are no local CO sources inside the bedrooms. Where there are fireplaces (even gas only) or vented or unvented heaters in a bedroom, prudence suggests going beyond the code and installing a detector within that bedroom.
(Or does the code actually have a provision for potential CO sources in a bedroom?)
