A. CO detector(s) shall be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms or sleeping rooms. Residential occupancies and residential dwellings shall be considered to be in compliance with this requirement if CO detectors are installed as follows:
1. Within a dwelling unit, on the ceiling or wall outside of each separate sleeping area within twenty feet (20') of any door leading to a bedroom or sleeping room;
2. Where sleeping units, or more than six (6) dwelling units, share a common hallway, on the ceiling or wall of the common hallway within forty feet (40') of any door leading to a dwelling unit or a sleeping unit; and
3. Within any sleeping unit where a CO detector is not located in the adjacent common hallway in accordance with subsection A2 of this section.
B. A residential occupancy or residential dwelling shall be considered to be in compliance with subsection A of this section, if CO detectors are installed and located in accordance with building codes in effect on January 1, 2007.
C. It is the intention of this chapter to implement the requirements of the existing building codes, including NFPA 720, effective February 7, 2005, to the greatest extent practicable for existing residential occupancies and residential dwellings. The building official or the fire marshal may approve alternative locations or methods for the installation of CO detectors, if the result would meet the spirit and intent of the building codes and NFPA 720. The building official, in coordination with the fire marshal, may also adopt written guidelines illustrating or describing required locations of CO detectors, and any approved alternative locations or methods for bringing residential occupancies and residential dwellings into compliance with the requirements of this chapter.
D. A CO detector is deemed approved for purposes of this chapter if it complies with all applicable state and federal regulations, and bears the label of a nationally recognized standard testing laboratory and meets the revised standard of at least UL 2034 dated October 1, 1995, and subsequent revision or its equivalent.
E. Each CO detector will be mounted in accordance with the manufacturer's instructions, though ceiling mounting is preferred. CO detectors will not be mounted in areas of low air movement (dead air spaces).
F. If a CO detector is required to be installed in a common hallway:
1. Any CO detector found to be tampered with shall be replaced with a hard wired device (missing or inoperable batteries shall not constitute tampering).
2. Any CO detector found to be missing a battery shall be replaced with a tamperproof CO detector with a sealed battery.
