Not in the business but in our building, and it is of newer and typical construction, the sprinklers are chained together in clusters. A single sprinkler is rarely sufficient to put down a fire, so having only one in a room or area trigger would not be effective in many cases. Having several trigger together gives greater fire suppression while also watering down the area to inhibit the fire's ability to spread.
