For a Multi-Fam Highrise, the corridors will be heated with a ducted roof-top gas furnace split dx system will be installed. No other combustion equipment nor combustion appliances will be located in the corridors or in the Res dwellings. Do the roof-top ducted gas-heat units for the corridors trigger the requirement for CO sensors to be located on each floor and in each Res dwelling?

ASHRAE 62.1-2010 does not address CO sensors, but the LEED BDC Reference Guide does include special language for CO sensors in residential buildings. By my reading of the RG, Carbon Monoxide sensors must be installed on each floor of the residential units regardless of HVAC system type. This is in line with other building and life safety codes that are concerned about preventing deaths from things like indoor grilling, or indoor use of generators (both surprisingly common).
