At Overhead Door Co. of Central Jersey, we often find there is confusion over maintenance and testing requirements for fire/smoke rated door products. We will focus primarily on overhead rolling fire/smoke doors for the purposes of this article. Let’s take a look at the basic drop testing and annual follow up maintenance requirements associated with these specialty doors.

Simply stated, the automatic closing of a fire/smoke rated rolling door must be tested at the time the door is installed, and then inspected and tested not less than annually as required by NFPA 80. This requirement applies to all fire/smoke doors – even those that are not used and remain in the closed position. The inspection and testing should be performed by a trained door professional and must be documented. DASMA (Door and Access Systems Manufacturer’s Association) provides guidelines for the inspection and testing of fire/smoke rated doors. Below is an overview of what an inspection and test should include.

Fire/smoke doors must be inspected and tested at least once a year

To begin, there will be an inspection of the guides, curtain slats, end locks, bottom bar, hood assembly, and operating mechanism. A part of the inspection is to verify that the operating mechanism, fuse links and release chain/cable are not painted, coated with dust or grease, and/or covered with debris. Once this visual inspection has been completed, the door will be operated to verify that it works smoothly and properly. During operation we often find evidence of damaged, worn or missing parts that may not have been evident in a simple visual inspection. The area around the door will be inspected for flammables. If there are any flammables in the area of the door, the client will be reminded that these items should be relocated.

With the visual and basic operation inspections done, assuming no deficiencies have been discovered, the door must now be drop tested. A drop test is simply a test of the automatic closure system on the door. For the drop test to pass, the door must close completely and rest on the floor or sill. The closing speed must average at least six inches but not more than twenty four inches per second. This test must be performed twice. The first test verifies proper operation and full closure. The second test verifies the automatic closure feature has been properly reset. This test should be documented. For this purpose we normally use a DASMA drop test form with a copy provided to the customer.

There are many reasons a door professional should perform the required inspection and testing. While we touched on the basics of inspection above, there are many details that need to be considered. Some of these details include proper location of the fusible links, proper mounting of guides and proper fire expansion clearances on guides and proper installation of any smoke detectors and/or release devices. It is also important that nothing that is not an actual part of the fire door assembly is attached to any part of the door.
