Building and fire codes require fire and smoke protection features to safeguard building occupants from fire hazards and hazards associated with smoke and hot toxic gases generated during a fire situation. This includes requiring fire-resistance-rated assemblies, such as fire walls, fire barriers, fire partitions, shaft enclosures and horizontal assemblies be provided to limit the spread of fire. This system of passive protection is an integral part of the overall fire safety approach taken by the model codes. This marking and application guide provides important information on limiting the spread of fire, smoke and toxic gases by protecting duct penetrations and air-handling openings in fire and smoke rated assemblies. There are five types of dampers recognized by the model codes for this purpose: fire, smoke, combination fire-smoke, ceiling and corridor dampers. UL certifies all five types of dampers in accordance with the requirements in model building, fire, and mechanical codes. These dampers and the applications for which they are certified are covered in detail in this guide. There are also duct protection methods that are an integral part of fire-resistance rated assemblies, and are described within the designs. See section 3. For information on smoke control systems, see NFPA Product iQ is free to use, but does require a one-time registration. UL has developed this guide for use by code and inspection authorities, architects, contractors, installers and other interested parties. It is intended to aid in understanding the types of dampers which exist, in association with the applicable codes and standards to facilitate safe, code-compliant installations. UL Marking and Application Guides are updated as necessary due to new product development, changes in the codes, or the need for clarification. This guide is intended to assist users to locate, specify or verify the correct type and code compliant UL Listed damper based on the use and installation location.

The following diagrams identify the components that make up complete assemblies, along with links to the guide information for the various product categories. Normal Duty Current: 96Amps. WG with a minimum closure pressure rating of 4 in, ul l501.

The airflow rating for a particular application is not necessarily one that matches the normal design airflow within the ducts. Additional information on periodic testing can be found in the model codes and installation standards. These dampers must restrict the spread of fire and the movement of smoke through the ceiling assembly. Leakage ratings of smoke dampers are established at a minimum differential pressure of 4 in. Digital LED technology provides high efficacy and energy efficiency. Products bearing any of these UL marks comply with the definition of a listed product in the code, and should be considered to be listed. Method 2. Some dampers may become fully isolated against the fan pressure. Each listing is specific with respect to 1 construction details of the ceiling in which the damper is installed, 2 the hourly fire-protection rating, 3 the damper leakage Class, 4 the minimum and maximum size of a single damper section. As with the basic installation instructions, the supplemental instructions are also an integral part of the UL certification program as the supplemental instructions are also reviewed by UL during the product evaluation. Each category code provides a link to the published product GuideInfo for that product and links to the products certified within that category. Heavy Duty Current: 96Amps. Heavy Duty Current: 1.

NFPA 80 covers the required inspection and testing of dampers and provides the testing frequency required for dampers. The information provided in the product GuideInfo is different from the overview and expanded explanatory information contained in this marking and application guide. All can be customized to your precise needs in industries such as oil and gas, mining, metals, chemicals, cement, power plants, material handling, pulp and paper, sawmills and marine. Smoke dampers listed by UL have a leakage class rating that indicates the level of air leakage measured through the damper under test conditions. L , L and M Heavy Duty Current: 77Amps. Ceiling dampers evaluated for use in specific fire resistance rated designs are covered under the Ceiling Dampers CABS category. Normal Duty Current: 2. Instructions are required to be shipped with each Damper for use by the installation contractor at the construction site. The fusible link must be reinstalled after testing is complete. In addition, any damaged products protecting duct and air transfer openings are required to be either repaired, restored or replaced.
