Back to Basics: Process Tips for Periodic Inspection of Fire and Smoke Dampers

  1. Verify that there is full unobstructed access to the damper
  2. Test the damper with normal HVAC airflow and verify that it opens following either Option 1 or Option 2. There should be no interference due to rust, damaged frame or blades, or other moving parts.

OPTION 1: Dampers with position indication wired to indication lights or control panels:

  • Switches can be wired to local or remote-control panels or building automation systems (BAS) to indicate that the damper is in the fully-open position, fully-closed position, or neither.
  • Use the signal from the damper’s position indication device to confirm that the damper is in the fully-open position.
  • Remove electrical power or air pressure from the actuator to allow the actuator’s spring return feature to close the damper.
  • Use the signal from the damper’s position indication device to confirm that the damper reaches its fully- closed position.
  • Re-apply electrical power to re-open the damper.
  • Use the signal from the damper’s position indication device to confirm the damper reaches its fully-open position.

OPTION 2: Dampers without position indication:

  • Visually confirm that the damper is fully-open position.
  • Ensure that all obstructions, including hands, are out of the path of the damper blades.
  • Remove electrical power or air pressure from the actuator to allow the actuator’s spring return feature to close the damper.
  • Visually confirm that the damper closes completely.
  • Re-apply electrical power to re-open the damper.
  • Visually confirm that the damper is in the fully open position.
  1. If the damper is not operable, it must be repaired as soon as possible. If the actuator has failed, replace it with a UL-approved actuator. After these repairs, the damper should be tested again.
  1. If there is a latch, verify that it is operable.
  1. Perform any other damper manufacture-recommended maintenance such as lubrication.
  1. Following the test and any repairs, document the location of the damper, the date, the inspector, and deficiencies or repairs. Keep the record for the life of the damper and have it available as you may need to show it to an inspector.
