Fire doors protect anyone in a commercial building from fire and other hazards. The National Fire Protection Association (NFPA) has outlined standards to ensure the safety of everyone working in and visiting commercial facilities. 

NFPA-80 section covers a range of safety standards and practices for fire doors. These requirements are essential for protecting your building and those inside it.

Fire Door Drop Test

NFPA-80 requires annual testing for all fire doors to ensure safety & operation. Our experienced & certified professional technician performs the inspection.

The door drop test follows NFPA® standards to assess the door’s automatic closure system. In a fire, the door should automatically close at the correct speed without issue. Before the actual drop test, a visual inspection will check for things like: 

• Malfunctioning operating mechanisms.

• Damages to the door components.

• Holes.

Fire Door Drop Test Requirements

The Door and Access Systems Manufacturers Association (DASMA) testing standards lay out the fire

door drop test procedure. Requirements:

• Free of debris and grease.

• At a safe distance from anything flammable.

• Free of damaged parts. 

Once it passes inspection, we close the door and monitor closing speed. The pace must be between

6” & 24” per second. This speed-check ensures the door can close fast enough to contain any fire or

smoke but not so quickly that it hurts anyone trying to get out. 

The drop test will include two steps: 

• Step one: The inspector will activate your drop-down fire door to ensure it closes within the

correct speed range and fully closes at the bottom. 

• Step two: The inspector will test your door again to ensure the automatic closing devices reset

when the door closed. 

If your door fails to pass the test, you can make repairs and test again. However, if the door fails to

pass the drop test after repairs, you should consider replacing it.

A fire door drop test is essential to maintaining your facility’s safety and security. A door that fails one

or both test sections is not a reliable safety measure. A door that closes too quickly, too slowly or

incompletely risks the safety of everyone on-site. Get Support From Gaithersburg Garage Door™ today!
