Can you define the term "fan room"??? We need a little more information here....
The maximum distance between fire sprinkler, per NBC, depends on the sprinkler system. The size of the sprinkler and the number of sprinklers need to be considered when installing.
almost 400 GPM
25-150 gallons per minute is standard depending on the type of sprinkler head. Residential sprinklers will be closer to 25. That flow is for a SINGLE sprinkler head. Typically the fire will be extinguished by just activating one sprinkler head.

It depends on the climate and how well your home is insulated.A good rule of thumb is about 20 BTUs per square foot.
"The average sprinkler will use in excess of 240 gallons of water per hour" also refer to http://www.libertylake.org/water_conservation.htm for watering guide. As a useful gauge: A garden hose with no nozzle attached, will spew out as much as 350 gallons per hour. So 240 sounds about right for a sprinkler system, keeping in mind that it will vary with your local water pressure and type of sprinkler system that you have. If your system has a damaged sprinkler head, you might as well be running that garden hose full blast. My sprinkler system uses 1,000 gallons in a three hour time cycle. I have six or seven zones. I suspect some of my heads are busted, since that sounds about like "garden hose figures." (333 gallons per hour)
