Sprinkler Systems

They are the most common type of commercial fire protection system. They use water to douse fires that have already started. Sprinklers can be mounted on ceilings or walls, and they will automatically turn on when there is a fire. The main downside to sprinkler systems is that they can take some time to reach a burning area.

Alarms

Alarms are another common type of commercial fire protection system. Alarms send alerts to people in buildings so that they can evacuate safely. Alarms can be manually operated or powered by batteries or electricity. They typically have a range of up to 500 feet, so they will sound even if someone is inside a closed room. 

Suppression Systems

Suppression systems use gasses or liquids to put out fires. Gasses can be used to create an atmosphere that prevents flames from spreading, while liquids can be used to put out small fires. Suppression systems typically use pressurized cylinders filled with chemicals or foam. When triggered, these cylinders release their contents into the air, putting out the fire .
