A60 Marine Fire Dampers

Marine A60 fire dampers are passive fire protection products used in the marine industry to prevent the spread of fire from inside the engine room or other fire rated space through fire-resistance rated walls and floors. Fire/smoke dampers are similar to fire dampers in fire resistance rating, and also prevent the spread of smoke inside the vessel. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to close the damper blades. Fire dampers can also close following receipt of an electrical signal from a fire alarm system utilising detectors remote from the damper, indicating the sensing of heat or smoke in the vessel occupied spaces or in the HVAC system

Regulations and fire test regimes vary from one country to another, which can result in different designs and applications, however, in Europe the body of certification is the Marine Equipment Directive (MED)
