CO detectors with built-in sounder bases installed in E, I-2 and I-4 occupancies in accordance with BC 908.7.2 must be installed in the following locations:
(1) Any room containing carbon monoxide-producing equipment, except kitchens and laboratories.
(2) Any corridor on the story where carbon monoxide-producing equipment unit is located, as well as one story above and one story below.

(2) Any corridor on the story where carbon monoxide-producing equipment unit is located, as well as one story above and one story below.
(6) Detection zones:
(i) Detection zones less than 10,000 square feet. Where carbon monoxide detection is required to be provided in a detection zone having an area less than 10,000 square feet, the carbon monoxide detection shall be placed in a central location within such detection zone.
(ii) Detection zones 10,000 square feet or greater. Where carbon monoxide detection is required to be provided in a detection zone having an area 10,000 square feet or greater, carbon monoxide detection shall be placed in a central location within such detection zone and at such additional locations with such detection zone as may be necessary to assure that no point in the detection zone is more than 100 feet from carbon monoxide detection.
(f) Equipment shutdown. Activation of a CO detector located at the source of CO-producing equipment must shut down that source. This provision does not apply where the source is a generator.
(g) Installation requirements. CO detectors must be installed in accordance with NFPA 720 – 2015 edition, as modified for New York City by this section.
