No. Just because a generator is present doesn't automatically require it to be connected to the fire pump.
The requirement of secondary or backup power for an electric fire pump is directly related to the reliability of the primary power source and other factors, some which may be code driven, some based on the function of the building and other reasons may be related to the contents of the building (hazardous materials). There are specific guidelines that typically are addressed or queried as part of the electrical power supply analysis by the project electrical engineer/contractor. (well, hopefully). NFPA 20, 2019 9.3.2 speaks about non-reliable power sources and additional criteria is defined within the appendix. Now, while this particular section is addressing High-Rises, the same application can apply to any building with contents or other conditions that absolutely must have an operational fire pump. So in the case of this building which has refrigerated consumables, whether or not the fire pump HAS to be operational in a power outage to protect the building and product is more of an owner/insurer preference. If the ice cream melts, it will be a mess but it will not endanger the public.

I'm on the road with no access to my books.If an emergency generator is installed on a building, is there anything in the codes that would require it to be connected to the fire pump. RichardL.
