What is the primary function of a fire sprinkler system?

The primary function of a fire sprinkler system is to extinguish fires and protect property. Fire sprinkler systems are designed to automatically release water when a fire is detected, effectively cooling the area, controlling the flames, and minimizing damage. This proactive approach not only helps in extinguishing the fire at an early stage but also provides valuable time for occupants to evacuate safely and for firefighters to reach the scene before the fire spreads extensively.

This protective measure is crucial in safeguarding both lives and property, making it a vital component of fire safety systems in buildings. While other options like alerting firefighters, monitoring air quality, and providing emergency lighting serve important roles in fire safety and emergency response, none of them fulfill the primary function of directly combating a fire, which is at the core of what fire sprinkler systems are designed to do.
