I would have to do a little research on it, but my knee jerk reaction is that he will not be able to feed anything else since it sounds like the generator is intended for the fire pump only.

If the generator can handle both loads, the concern now becomes what does this do to the fuel calcs and run time since there will be a new load imposed on the generator.

I would run this one by both the EI and the Fire Inspector to make sure its good. Depending on what they determine, you may have to have an engineer supply load calcs for both and ensure that the run time of the fire pump meets the minimum requirements for your jurisdiction.

anbm,

Short answer, Yes it can be done. Lots of things have to be properly arranged.

Here's an article of interest.
