The bottom line is that the automatic water supply doesn't have to be sized for the standpipe system if it meets the provisions for a manual/wet and satisfies the sprinklers, whether or not that water supply is a pump or waterworks connection.
Steve Leyton PROTECTION DESIGN & CONSULTING I agree on non high-rise if the available automatic supply (street pressure) satisfies the sprinkler demand to allow you to carry your hose demands in design based upon whatever residuals the street pressures allow but I just can't see where it allows you to size a fire pump and all it's components to only provide the sprinkler demand of the system. I just don't think that it should be allowed. Sure, if it's designed based on street pressures let it fly and they can connect a hydrant and pump and boost whatever they need for their lines. I think it raises design (pipe size) issues, operational problems (first responders pumping against a pump or what if they just head up and connect a hose and attempt to use the building's fire pump) among other lesser issues. I don't see where the current standard specifically allows this but I see how it can be done under the "if it doesn't say we can't" claim. If I was a committee person I wouldn't let this go through.
