Life Safety Dampers


Passive Fire Protection (PFP) systems contain fire and smoke to predetermined areas of a building, to prevent it from quickly spreading through the rest of the building. COSMOS Life safety dampers are installed in HVAC ducts, partitions and wall penetrations to support the PFP system to protect life and diminish property loss during a life safety event .There are four types of life safety dampers available with COSMOS: motorized fire dampers, fusible link fire dampers ,smoke dampers and combination firesmoke dampers.
