All fire protection systems need regular testing and maintenance to guarantee the safety of the occupants of the building. A fire damper is one of the most important components of passive fire protection equipment that is fitted into the ducts of heating, ventilation and air-conditioning.
Why is it important?
It is installed to prevent the spread of fire to other areas of the building. Fire dampers work when heat from fire crosses the limit of 165degrees Fahrenheit. It is designed to close automatically due to the presence of heat-sensitive fusible links and thermal elements. Fire damper maintenance is required to be carried out by professional personnel who have the required knowledge and skill to deal with any faulty damper.
What is a fire damper drop test?
The fire dampers are installed in the ducts and are typically held open by a fusible link which is designed to release a fire shutter upon detection of high temperatures. When the temperature is detected, the fusible link releases and closes the damper. A drop test is done to ensure that the damper is reset correctly so that it can function in an emergency.
What to look out for during a drop test?
It is important to ensure that the closing mechanism of the damper is working properly. It is also necessary to see that the dampers are located at quick and easy access points. Also ensure that there is no accumulated dirt or debris around the damper.
