How many fire sprinkler heads are needed for a fire department connection to be installed?
In the past the FDC was optional. NFPA 13: Standard for the Installation of Sprinkler Systems now requires the connection except for systems of 20 sprinkler heads or less, or when permission has been obtained from the authority having jurisdiction.
Sources- Brannigan & Corbett- Building Construction for the Fire Service (4th Ed) 2008. The above is a direct quote on page 288 if you so need it for a paper.
So when you have more than 20 sprinkler heads, or when you have obtained permission.

How much water is needed for a sprinkler system?
The most common fire sprinkler system is a wet pipe system wich always has water in it. The sprinkler heads have a heat sensitive element, most commonly a glass bulb filled with liquid that expand when exposed to heat, after a certain temperature is met , usually 160 degrees or more the glass bulb breaks and allows water to flow on the fire in a uniform water density. The sprinkler system may have an alarm device that sounds an audible alarm in the building, and/or call the fire department. The system may have a connection for the fire department to add to the automatic water supply. there are other types of systems, dry-pipe, preaction, and others which are similar but do not have water in the piping initally due to concerns of freezing water in the system, or sensitive areas where accidental water damage would be a greater problem than fire.(museums, computer rooms, etc)
