We have called for and have had installed similar pumps in a fire pump situations. So here is a possible understanding of this situation and a way to make a proper judgement call if you are in that AHJ position.
Our pump setups were such that you had the regular fire pump, but because the domestic water could not keep up with fire demand (such as a well or end of a limited domestic supply and you don't want to collapse the water lines by pumping to hard), or if the system is required to have an antifreeze due to winter time shutdown of the facility (yes, I know of the UL bulletin on cease and desist these types of systems while they investigate), a secondary storage tank with an air break is needed (avoids cross contaminations). So a pump that cannot keep up with fire flow, but with the storage of the tank can for the required time (figured out by someone else) is installed. This pump must be treated as a fire pump as it is a required part of the fire sprinkler system.
So look at the pumps purpose, if it is an integral part of the fire proetection system, even if seeming ancillary, treat it the same as a fire pump.
I hope that this doesn't cloud the waters.
