Which fire protection system is designed to extinguish fires automatically?

The correct answer is the Automatic Sprinkler System. This type of fire protection system is specifically designed to detect and control fires automatically, often before they can spread significantly. The system consists of a network of pipes, valves, and sprinkler heads that deliver water to the fire when a fire is detected. Each sprinkler head is activated by heat, meaning when the temperature rises to a certain level, it opens and releases water directly onto the fire.

In contrast, manual fire extinguishers require human intervention to operate, meaning they do not activate automatically. Fire alarm systems are designed to detect smoke or fire and alert occupants through alarms, but they do not extinguish fires themselves. Fire smoke control systems are intended to manage smoke movement and improve visibility and escape routes during a fire, but they do not have the capability to extinguish the flames. Thus, the automatic sprinkler system is specifically engineered for the purpose of automatically extinguishing fires, making it the correct choice.
