Initially, proper testing should be done during its installation which is operational testing ought to be done of fireside damper to guarantee that it is functional then there is full access to it too becasue it is components, verification should be done that all the tools are placed properly in their appropriate places, along with other important verifications. All this testing done should then be documented which includes all details in regards to the fire damper instructions regarding its installation.
After the duration of one year of installation of fire and smoke dampers, it's important to be inspected according to the National Fire Protection Standard and then the frequency should be every Four years and 6 years for hospitals.
The following activities must be performed during the time of inspection:-
1] The fusible links for fire dampers where it's applicable needs to be removed for testing purpose.

• Make certain that damper is able close fully.
• There shouldn't be blockage from your closure and should not penetrated by foreign objects as it affects fire damper operations.
• It ought to be ensured that if fusible link is broken than being substituted for a link of the size, temperature, and load rating.
Thus testing and security precautions are important to be done this concerning make sure that it works at its best during fire and life safety event where it is most significant to work. It is crucial for doing inspections regularly so that the method is always ready because we don't know once the unexpected event will probably occur.
