NFPA Regulations for Fire Damper, Fire/Smoke Damper, and Smoke Damper Testing Frequencies

NFPA 80

19.5.1.1 Each damper shall be tested and inspected 1 year

after acceptance testing.

19.5.1.2 The test and inspection frequency shall then be every

4 years, except in buildings containing a hospital, where the

frequency shall be every 6 years.

NFPA 90A

7.2 Fire Dampers, Smoke Dampers, and Ceiling Dampers. All

fire dampers. smoke dampers, and ceiling dampers shall be

Testing and Inspection Procedure:

• Locate each damper and confirm that it is in a rated barrier.

• Conduct a physical and visual inspection of all damper components to verify the equipment’s functionality.

• Make adjustments or install replacement components as required.

• Verification of damper location.

• Label damper location and ID# on ceiling grid and life safety drawings.

• Tag damper using Rpm, LLC label identifying the following:

• Damper ID#

• Inspection Date

• Pass, Fail or Non Accessible Rating

• Determination of access to damper, access door, damper blades and external components.

• Picture of damper in its current state “Before”. (optional)

• Clean each damper of any debris that would impede normal operation.

• Lubricate damper track to ensure proper operation.

• Removal of fusible link.

• If the damper is a smoke or combination type damper the power source shall be removed from its actuator in order to verify damper closure.

• If the testing of the damper fails or is inaccessible a best solutions recommendation will be given for correction at a later time.

• Solutions to inaccessible dampers; installation of access doors, relocation of dampers, rated wall reconfiguration, fire rated duct insulation, etc…

• Damper assessment spreadsheet detailing ID, location, damper type, fusible link rating, pass/fail status, correction recommendation and additional comments.

Corrective Measures

• Installation of sheet metal access doors.

• Installation of access doors in solid ceilings.

• Installation of rated access doors in shaft-walls.

• Relocation of of fire/smoke dampers and sheet metal modifications.

• Installation, repairs and/or replacement of damper assembly, actuators and/or linkage.

• Install rated duct insulation in the event the damper is located to far from rated wall.
