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.

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.

The correct damper depends on the application. The closure pressure rating is not the pressure drop across an open damper. Multiple power and light levels are offered as standard to allow meeting design and energy needs per application. Enclosed and gasketed linear ambient LED luminaire. Like any mechanical device, dampers require periodic maintenance to ensure continued proper operation. Smoke dampers listed by UL have a leakage class rating that indicates the level of air leakage measured through the damper under test conditions. Method 2. See section 3. Normal Duty Current:. Smoke dampers are designed to operate against air velocity and fan pressure. Data Sheet.

Ducts are attached to the damper sleeve using breakaway methods. Anyone directly involved with a product — including manufacturers, owners, contractors, and regulatory authorities — can request a field inspection or field evaluation. Openings in these assemblies must be protected in a manner which compliments the intent of the assembly. As such, the ceiling damper must likewise retard the passage of heat. Voltage Range: V. Normal Duty Current: 2. Heavy Duty Current: 1. Additional information on periodic testing can be found in the model codes and installation standards. Comments Required. Nominal 2Ft. Some manufactures elect to provide basic instructions that cover only common installations, and then rely on supplemental instruction pages that cover unique installation scenarios.
