Fire dampers play an important role in preventing fire from spreading to other areas of building in case it has reached your ventilation system. Fire dampers are designed in such a way that they can help in preventing fire from spreading through ductwork. These are basically safety products that are used in ventilation, air conditioning and heating ducts.

They are prepared using fire resistant materials so that fire spread can be prevented. In fact, design of these dampers is such that fire can’t spread inside ductwork. Fire dampers can be life savior for all people who’re present in the fire prone building. Following section will brief you how fire dampers actually work.

Functioning of Fire Dampers

When fire damper gets signal of high temperature in the duct, it is closed for preventing fire to get through the duct. This actually occurs after that fusible link melts because of high temperature. Fire dampers can also function with fire alarm system. In this case, fire dampers are alerted about the presence of fire after getting an electric signal from the fire safety alarm. In this case, there needs to be installation of a detector remote in damper. This detector will help to sense smoke or heat in duct system or the building.

If installed in a right way, fire dampers can help to prevent considerable damage. However, the problem is that in some buildings fire dampers aren’t installed properly due to which they don’t function in the right way.
