This isn't really an NEC issue but I don't know how else to find out in a hurry what might be required.
This bid is for an eight story apartment building in Quincy, Mass, where I am pricing the electrical work involved in the removal of existing oil burners and replacement with gas fired boilers for building heat and domestic hot water.
The spec says to include CO detectors in the basement and any other areas required by code. These are high effeciency boilers that take air from ducts tied directly to the outside. I have no idea what might be required for CO detectors and there isn't an engineer to ask.
I assume the building has a seperate fire alarm system and it probably has a security system. I also assume if CO detectors are installed in just the boiler room it will not be heard by anybody until someone happens to open the BR door. Seems like it should be tied into the fire alarm panel but I don't know. If it ties into the existing FA panel or on one of the zones I would sub it out but I wouldn't know what to carry for that in the bid.
