Fire fighting systems are a collection of devices and equipment designed to detect, control, and extinguish fires. These systems include fire alarms, sprinklers, hydrants, extinguishers, and suppression systems using water, foam, or gas. They are installed in buildings and industrial facilities to protect lives and property by minimizing fire damage. Fire fighting systems can be manually operated or automated, with detection systems triggering alarms and suppression mechanisms. Regular maintenance and inspections are crucial to ensure their effectiveness in an emergency.
