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.

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.

Fire dampers for use in dynamic systems are required at locations where fan pressure and airflow continue to operate during a fire incident, and as such, the dampers are expected to operate close against the air velocity and pressure produced by the system fan. This system has been investigated for effectiveness in restricting the transfer of heat into the concealed space above the ceiling. Refer to the section in this guide entitled Ceiling Dampers under Damper Types for a detailed explanation of the limitations of the certifications applied to ceiling dampers. The GuideInfo provides additional details regarding the design, construction, and use of these assemblies. The UL certification of ceiling dampers does not cover the products for general installation in any floor-ceiling or roof-ceiling design. UL Marking and Application Guides are updated as necessary due to new product development, changes in the codes, or the need for clarification. Fire dampers are designed to close automatically when heat is detected, and are used to restrict the spread of fire where ducts and air transfer openings penetrate fire walls, fire barriers, fire partitions, horizontal assemblies and shaft enclosures. The shaft should be penetrated horizontally so that vertical dampers can be used to protect the penetration through the shaft. As a general rule, vertical ducts rising through fire rated floors are to be protected by fire rated shaft enclosures. Quick view.

Multiple power and light levels are offered as standard to allow meeting design and energy needs per application. It does this by regulating the installation, operational testing, periodic inspection and maintenance of these dampers. Price Now. Highlights Intuitive control panel and PC tool Direct torque control DTC for precise open and closed loop control Built-in safety features for simplified configuration Communication with all major automation networks Removable memory unit for easy drive commissioning and replacement Energy optimizer and energy efficiency information for monitoring and saving energy Designed for easy service. The building codes specify where fire dampers are required, and establish how the fire damper is to be installed in the field. Dampers must be tested and inspected 1 year after initial acceptance testing, and then the test and inspection frequency for dampers is every 6 years in a hospital, and every 4 years for all other buildings, thereafter. Voltage Range: V. 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 can be used in HVAC systems where the fans are shut down in the event of fire, and can also be used in smoke control systems designed to operate during a fire incident. 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. As the fire resistive shaft rises through the structure, it is not necessary to protect the opening at the floors the duct passes through because the duct is located in a fire rated shaft. The control requirements of NFPA 90A include provisions for manual and automatic control of smoke and combination fire-smoke dampers. Refer to the section in this guide entitled Ceiling Dampers under Damper Types for a detailed explanation of the limitations of the certifications applied to ceiling dampers.
