All fire safety systems must be regularly and professionally maintained to ensure the safety of building occupants - a faulty fire damper will not prevent the spread of fire. Because the damper is designed to close automatically, they must make sure it is not blocked and that any object that will affect the operation of the frame is not penetrating it. They also need to confirm that the fusible link has not been painted or damaged because this will prevent the damper from engaging in the event of an emergency.
It doesn't matter whether you own the building, sub-let the building or are merely a tenant, it is your responsibility to ensure the safety of your employees and visitors to your premises. These regulations fusible links for fire dampers have recently been changed with the update of BES:9999:2017 from BES:9999:2008, bringing motorized dampers into line with mechanical dampers which were previously only expected to be tested every two years.

When it comes to preventing the spread of fire and smoke in an emergency Fire Dampers are crucial, as they play a crucial role in the fire safety system of a building, Fire Damper inspections should be carried out to ensure they are working to their optimum.
According to the BS9999 Fire Damper Regulations, arrangements should be made for all fire dampers to be tested by a competent person on completion of installation and at regular intervals not exceeding two years (HTM03-1 requires hospitals to have their dampers tested every 12 months).

Testing are required to ensure these dampers function as intended in a fire emergency Dampers Requiring a Fusible Link to Operate - Most Fire Dampers and. Fire dampers are installed in penetrations of fire rated walls and floors as required by the building code and access to the damper itself is normally through an improperly sized access door.
We have the most comprehensive range of fusible inks on the market today used in a wide range of applications including fire dampers, fire safety doors and extinguishing systems, ventilation hatches, fire curtains and much more. A Fire Damper inspection inspects and test the mechanics of the fire dampers, to ensure they are well maintained and working correctly in the event of a fire.

When dynamic dampers are present, testing in normal HVAC operation with air flow is the only way to prove its operation in the case of an actual event. In Direct Fire (Thermal) operation, the Bi-metal Link is three times faster acting than the UL maximum standard for fusible links.
