It's ice cream; depending on local health code requirements, a "save" might still be a profound or total loss.
After a long time in this racket, I find myself falling back more and more on Chapter 1 of all the standards wherein we find the intent statement, which is to provide a "reasonable" level of protection against fire. If they want/need a generator to keep ice cream from melting in this fully sprinklered building, then plug one in. But it's also fair to undertake a cost/benefit analysis if backing up the pump means doubling the cost of the gen set and if the owner doesn't see the value, so be it. Keeping in mind that at no point in this discussion has there been any allusion to the power supply not meeting the reliability requirements of NFPA 20.

If they size the generator to handle the fire 150 hp fire pump load it will double the price he says. -----Original Message----- From: Steve Leyton via Sprinklerforum <[email protected]<mailto:[email protected]>> To: Richard Mote <[email protected]<mailto:[email protected]>>; [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> Cc: Steve Leyton <[email protected]<mailto:[email protected]>> Sent: Thu, Aug 26, 2021 8:15 pm Subject: RE: Transfer Switches To paraphrase, you're asking if it's required to connect a gen set that is installed in a building that isn't a high-rise building or some other essential facility where there is a code requirement for emergency power, correct? In other words, a voluntary generator with regard to the code set. Assuming that's the case and there isn't a formal interpretation from the AHJ regarding the reliability of the power supply, I would say no. The code will require an emergency power supply or not. If one is required, then the FLS systems have to be on that, but if the secondary isn't required by code then it's up to the owner (and let's face it, that's certainly a good idea if the generator is sized for the fire pump). So there MAY be something in the code that requires this, but only if it's a mandatory generator.
