What is the primary purpose of a fire sprinkler system?

The primary purpose of a fire sprinkler system is to control or extinguish fires by discharging water automatically. This is achieved through a network of pipes and sprinkler heads strategically located throughout a building. When a fire occurs, the heat activates the sprinkler heads, allowing water to flow out and suppress the flames. This automatic response is crucial in minimizing damage, protecting lives, and controlling the spread of fire until other firefighting measures can be employed.

While other options mention functions that may contribute indirectly to fire safety or building services, they do not directly address the sprinkler system's main role in fire protection. For instance, enhancing aesthetic appeal, increasing water pressure, or improving air quality might be beneficial aspects of a building or its systems, but they are not related to the fundamental goal of a sprinkler system, which is the immediate response to a fire emergency.
