Pre-action system

Preaction systems utilize closed sprinklers, compressed nitrogen or air in the system piping, and water under pressure held below the clapper of the valve. Preaction systems require a detection and release system. When activated by a detector, the valve opens, allowing water to flow into the system pipe and sounding an alarm. When the heat source activates a sprinkler, water flows through only the open sprinklers.

Passive protective system

Passive Fire Protection (PFP) systems are important ‘buildt-in’components of structural fire protection and fire safety in a building.  They compartmentalise a building through the use of fire-resistance rated walls and floors, keeping the fire from spreading quickly and providing time to for people to escape from the building.

Structural fire protection ensures the stability of structural elements (such as steel, concrete or timber beams/columns) in the event of a fire. This is reached by applying adequate products onto the structural element, such as boards or sprays.

Compartmentation is a defined area in a building constructed to prevent the spread of fire and smoke from another part of the building (or an adjoining building) to create a ‘box’. Compartments are always vertical (fire rated floors/ceilings) and horizontal (fire rated walls) and are often penetrated by services such as cables, pipes and ducts. These penetrations need to be sealed in order to maintain the tightness of the compartment.
