Components of a Fire Suppression System

When people think about fire suppression systems, they mostly tend to think of active suppression such as sprinklers and extinguishers. There are two types of fire suppression systems, and along with that, we’ll be breaking down the components of a fire suppression system and a fire sprinkler system in this article.

Fire sprinkler system is a type of fire suppression system that have two types substances being released. Wet fire suppression systems are overhead sprinklers that are connected and  filled with water that is under pressure. Once it reaches a high temperature point, the system will extinguish fire using water until firefighters arrive. Dry fire suppression systems are charged with compressed air, or different substances. When the sprinkler operates, it releases air and the control valve opens, allowing water to flow from the pipe and emit chemicals, gas, or foam agents.
