What is the primary function of a fire sprinkler system?

The primary function of a fire sprinkler system is to control or extinguish fires by spraying water. Fire sprinklers are designed to activate automatically when a fire is detected, typically through the heat generated by flames. Once triggered, they release water directly onto the area of the fire, helping to either control its spread or extinguish it entirely. This capability is crucial for minimizing damage and protecting lives in residential and commercial buildings.

While other options may relate to safety and fire prevention, they do not encompass the main role of a fire sprinkler system. Providing light during a fire may aid in evacuation but is not a function of sprinkler systems. Monitoring smoke levels is important for fire alarms but is not something fire sprinklers do. Preventing water contamination is essential in various plumbing scenarios, but it does not pertain to the primary function of fire sprinklers, which is solely focused on fire suppression.
