If your commercial building has a rolling fire door, NFPA 80 and Model Codes require that it be tested and inspected. During the inspection, doors must demonstrate proper operation, full closure, and proper reset. Tests are meant to assure protection of walls, floors, and ceilings against the spread of smoke and fire in and out of the building. The following checks must be performed during fire drop testing.
Fire Door Drop Testing
Inspection: A technician will visually inspect the system to determine if anything is hazardous or could cause a problem or affect operation or resetting.
Operational Check: The technician will also watch how the door operates as it opens and closes. If the door is imbalanced, it will need to be corrected. Any damaged parts will be replaced. The door should be left to function properly once the operational check is complete.
Drop Test: The drop test is given to assure that the fire door will close on its own in an emergency situation. Closing speed must be between six and 24 inches per second.
Drop Test Form: The correct forms and paperwork must be filled out for the customer’s file, and a verification letter will be sent if necessary.
