  1. Units on the same story where carbon monoxide- producing equipment or enclosed parking is located.
  2. Units on the stories immediately above and below the floor where carbon monoxide-producing equipment or enclosed parking is located.
  3. Units in a building containing a carbon monoxide-producing furnace, boiler, or water heater as part of a central system.
  4. Units in a building served by a carbon monoxide- producing furnace, boiler, or water heater as part of a central system that is located in an adjoining or attached building.

908.7.1.1.1 Required Locations Within Dwelling Units

Carbon monoxide alarms or detectors shall be located within dwelling units as follows:
  1. Outside of any room used for sleeping purposes, within 15 feet (4572 mm) of the entrance to such room.
  2. In any room used for sleeping purposes.
  3. On any story within a dwelling unit, including below-grade stories and penthouses of any area, but not including crawl spaces and uninhabitable attics.

908.7.1.1.3 Exhaust of Carbon Monoxide in Group R-3 Occupancy (One- And Two-Family Dwellings and Townhouses)

Means of exhausting carbon monoxide from garages shall be provided when a carbon monoxide alarm or detector is activated in a Group R-3 occupancy, provided such garage is attached within the Group R-3 occupancy. Such exhaust system shall be arranged to operate automatically upon detection of a concentration of carbon monoxide of 35 parts per million (ppm) or greater by approved automatic detection device. The system shall be capable of producing an exhaust rate of 1.5 cfm per square foot of floor area of the garage. Removal of sensor, interruption of power or cut wires shall cause the relay circuit to open and start fan. The relay contact shall close and the fan may shut off when the carbon monoxide level is below 35 ppm. Carbon monoxide exhausting means shall be connected to a separate circuit and provided with a lock and identified at the power source. Such circuit shall not be connected to a power source through an arc-fault or Ground Fault Circuit Interrupter (GFCI) devices. Additionally, when the carbon monoxide exhausting means is connected to the plug-in-type overcurrent protection device, such device shall be secured in place by an additional fastener.
