Many properties have complex HVAC systems to provide air conditioning and clean air. They are essential but can cause issues. The concern is they create routes that fire and smoke can use if there is a fire in the property. This could allow them to spread quickly and put more people at risk of being unable to evacuate. The solution is to use dampers and get regular fire damper tests to ensure they will work properly.
The most common type of fire damper is quite basic. They have a curtain or series of interlocking blades that can fall into place to seal off the duct. This will happen when the temperature in the duct exceeds safe limits and causes a fusible link to release. Then all it takes is for gravity to do the work and pull the curtain down.
Curtain dampers must meet the right regulations to ensure they will perform properly. Most importantly they have to comply with BS EN 15650. The latest version of the standard is from 2010. It includes the specific requirements for these dampers, covering both the design and testing needs.
All of these dampers must have a suitable level of fire resistance. The idea is to seal off the ducts to stop fire and smoke in its tracks. To do this the housing of the damper and the curtain must be fire resistant. They have to survive for a specific length of time even if there is a blazing fire in the duct.
