Active fire protection systems include automatic features to protect a building and its occupants from fire. It uses moving mechanical or electrical parts to achieve the fire protection goal. Active fire protection systems attempt to contain the spread of the fire by dispersing water or other compounds.
Active fire protection systems are installed based on occupancy and building size. It’s also generally considered best practice to add extra active systems in areas that may contain more sensitive equipment, or that may have a higher than average risk, such as areas with flames or cooking implements.
In comparison, passive fire protection systems contain fires without taking action by utilizing building compartmentalization through the use of fire-resistant walls, doors, and coatings.
Buildings often use both active and passive fire protection systems to gain maximum protection.
