FSD Fire & Smoke Damper Installation & Maintenance 5

Question 1

Under NFPA 105, smoke dampers must be inspected and tested within how many months of building occupancy?

Accepted Answer

6 months

Answer

NFPA 105 requires smoke dampers to be inspected and operationally tested within 6 months after the building is occupied for the first time.

Question 2

What is the correct method for testing a fire damper's fusible link without actually melting it?

Accepted Answer

Manually trip the damper by removing or releasing the fusible link and then reinstalling a new one

Answer

To test a fire damper, the fusible link is manually removed to allow the damper to close, then a new link is installed and the damper is reset to verify proper operation.

Question 3

Which condition would cause a smoke damper to FAIL an operational test?

Accepted Answer

The damper closes but a position feedback signal is not returned to the FACP

Answer

If the damper closes but position confirmation is not transmitted back to the fire alarm control panel, the system cannot verify closure and the test fails.

Question 4

When a fire damper is installed in a duct system with flexible duct connections, where must the damper be located relative to the flexible connector?

Accepted Answer

The damper must be in rigid duct, not connected to flex duct at all

Answer

Fire dampers must be installed in rigid duct sections; flexible connectors cannot be used at or through fire-rated assemblies where dampers are required.

Question 5

A contractor installs a fire damper with the airflow arrow pointing opposite to actual airflow direction. What is the primary risk?

Accepted Answer

The damper blades may not close reliably under fire conditions

Answer

Fire dampers are designed to close in a specific airflow direction; reversing airflow can prevent the blades from fully closing under fire conditions, defeating the damper's purpose.
