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

Dampers commonly fall into five types, ul l501 with a specific function and end-use application. Anyone directly involved with a product — including manufacturers, owners, ul l501, contractors, and regulatory authorities — can request a field inspection or field evaluation.

Rating Required Select Rating 1 star worst 2 stars 3 stars average 4 stars 5 stars best. The fusible links used in fire dampers are certified to UL 33 , Standard for Heat Responsive Links for Fire-Protection Services, temperature classifications and ratings. Heavy Duty Current: 96Amps. The following diagrams identify the components that make up complete assemblies, along with links to the guide information for the various product categories. Enclosed and gasketed linear ambient LED luminaire. Multiple power and light levels are offered as standard to allow meeting design and energy needs per application. The maintenance requirements include topics such as changes in the airflow and noise from the duct, lubrication and required documentation. Data Sheet. Types of dampers include fire dampers, smoke dampers, combination fire-smoke dampers, ceiling dampers and corridor dampers. Corridor dampers have also demonstrated acceptable closure performance when subjected to fpm velocity across the face of the damper during fire exposure. The fusible link must be reinstalled after testing is complete. Smoke dampers are investigated for use in specific vertical or horizontal assemblies as specific in the installation instructions supplied with the product. Duct Outlet Protection System B may be used in any design which contains a steel duct with the duct outlet protected by a hinged door damper, for equal or smaller outlet size. Wet location.

Occasionally code authorities ask to receive copies of UL standards that are referenced in the code they are enforcing. In most cases it is not necessary to obtain the actual UL standard to determine code compliance. That information should assure code authorities that a product was evaluated to the appropriate product standard, as referenced in the code.

ABB Drives Videos. Since there are multiple types of dampers for use in protecting openings in horizontal assemblies, it is important to carefully consider the proper damper for each application. Operational test shall demonstrate the damper is installed and functions as intended. The installation requirements of NFPA 80 include topics such as damper location, listing and labeling requirements, preparation of openings, securement, access to fusible links and serviceability. Smoke dampers have a minimum airflow rating of 0 fpm and a maximum airflow rating as marked on the damper. Each listing is specific with respect to 1 construction details of the assembly in which the damper is installed, 2 the air leakage rating, 3 the damper mounting position i. The specific equipment investigated under this program bears the UL Field Evaluation label. UL Marking and Application Guides are updated as necessary due to new product development, changes in the codes, or the need for clarification. UL listed for wet locations. The product GuideInfo is a technical document which details the scope of the products covered, information relating to limitations or special conditions applying to the product, the requirements used for the investigation of the products and general installation and use information. An approved means for proper access to the damper for inspection, testing and maintenance must be provided for each Damper installation. Like any appliance, field servicing of these products is not covered under the scope of the UL certification program.
