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.

Where a vertical duct penetrates a horizontal assembly without a shaft enclosure, a horizontal fire damper is required. These dampers and the applications for which they are certified are covered in detail in this guide, ul l501.

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. If there is a need to access the UL Standards this can now be done using our complimentary web based service.

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. Further, the mullions are limited to use in vertical partitions. Heavy Duty Current: 96Amps. The installation requirements of NFPA include topics such as damper location, damper actuator and linkage, access to fusible links and serviceability. Normal Duty Current: 96Amps. The maintenance requirements include topics such as changes in the airflow and noise from the duct, lubrication and required documentation. L , L and M It does this by regulating the installation, operational testing, periodic inspection and maintenance of these dampers. Quick view. 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. Voltage: V. Dynamic ceiling dampers are required at locations in which fan pressure and airflow remain in operation during a fire incident. These devices are installed to operate automatically, controlled by a smoke detection system, and, where required, capable of being positioned from a remote command station. Although these ratings relate to individual dynamic ceiling damper models it is important to note that both static and dynamic ceiling dampers do not have an assigned hourly fire-resistance rating. The fusible link must be reinstalled after testing is complete.

If a fusible link appears to be damaged or painted when inspected, it must be replaced with a listed link that is functionally equivalent and has the same temperature and load rating. Voltage Range: V. Smoke dampers are designed to operate against air velocity and fan pressure. Carolina Motion Controls Videos. Corridor dampers are investigated for use in specific horizontal ceiling constructions as specified in the installation instructions supplied with the product. UL listed for wet locations. The ratings must be compatible with the ratings of the smoke damper. Each category code provides a link to the published product GuideInfo for that product and links to the products certified within that category. This method of construction consists of a combination of protecting the inside of rectangular shaped steel ducts with a minimum 1 in. Heavy Duty HP: 7. The operational test shall demonstrate the damper is installed and functions as intended. Authorities having jurisdiction should field-test various combinations of opened and closed dampers to represent the worst expected condition across the damper.
