Greenheck’s worldwide leadership in providing cost-effective, value-added solutions for air movement and control challenges evolved from rather humble beginnings. Bernie and Bob Greenheck weren’t sure what lay ahead when they opened their small sheet metal The first factory. 1947 shop in Schofield, Wisconsin USA in 1947. But they were determined that no product would ever leave their shop, unless it met the most stringent quality standards—their own. At first, the company manufactured a variety of sheet metal products. In 1956, Greenheck engineers developed a highly efficient power roof ventilator. This product and the innovative ventilation solutions that followed ultimately enabled us to expand our distribution throughout the world. Today, quality Greenheck products are efficiently moving air in commercial buildings, institutions and factories throughout North America, Latin America, the Middle East, and Asia. Customer driven employees. Greenheck employees continue to share an extraordinary commitment to meeting and exceeding customers’ Bernie and Bob Greenheck expectations. We know our future success depends on the 1956 value we bring to the market: reliable, top-quality products and exceptional service.

4 Life Safety Dampers

Life safety dampers are intended to protect openings in walls, ceilings, ﬂoors and/or partitions to prevent the spread of ﬁre and/or smoke. The four types are: Fire Dampers Smoke Dampers Combination Fire Smoke Dampers Ceiling Radiation Dampers

Fire Dampers are required by building codes to maintain the required fire resistance ratings of walls, partitions and floors when they are penetrated by air ducts and transfer openings. These products are tested and classified in accordance with UL Standard 555.

Smoke Dampers have two applications: 1. They may be applied in a passive smoke control system where they simply close and prevent the circulation of air and smoke through a duct or a ventilation opening in a smoke barrier. 2. They may be applied as part of an engineered smoke control system designed to control the spread of smoke using the building’s HVAC system and/or dedicated fans to create pressure differences. These products are tested and classiﬁed in accordance with UL Standard 555S.

Combination Fire Smoke Dampers perform the function of both a ﬁre damper and a smoke damper. These products are tested and classiﬁed in accordance with both UL 555 and UL 555S.

Ceiling Radiation Dampers are designed to protect penetrations through the ceiling membrane of ﬁre resistive ﬂoor ceiling and/or roof ceiling assemblies. These products are tested and listed in accordance with UL Standard 555C and 263.

5 Codes and Standards

The terms “code” and “standard” are often used interchangeably but there is a fine point of difference. A code is a set of regulations and requirements written in appropriate language with the expectation that it will become law. A code is enacted into law when it is adopted by formal action of a governing body or other authority having jurisdiction. A standard is not necessarily written with the expectation that it will be adopted by some authority having jurisdiction and become law. Rather, a standard is intended to establish a defined level of performance or requirements, and often includes a listing of the necessary tests and qualifications for compliance with the standard. Codes often reference standards making them a part of the referencing code. For example, the 2018 International Building Code references UL (Underwriters Laboratory Standard 555 as the appropriate standard for qualifying fire dampers for use under the International Building Code. Compliance with the Applicable Building Codes is Mandatory If a state, city, or other authority having jurisdiction has adopted one or more codes governing construction within that jurisdiction, these codes are the law and must be followed. As there are many code documents in existence that have not been adopted by every authority with jurisdiction, it is important that both the designer and contractor know exactly what codes are applicable to the building in question. The intent of the International Building Code is to provide minimum requirements to safeguard the public health, safety, and general welfare of the occupants of new and existing buildings and structures (2018 IBC, page ix). The subject of codes and standards cannot be treated in any depth in the space available in this manual. See installation instructions and installation supplements for specific information. The National Fire Protection Association The National Fire Protection Association merits special mention because of its significance as a standard writing and trend setting organization in the fire and life safety arena. NFPA, a non-profit membership organization founded in 1896, brings together all interested parties to promote safety from fire, electricity, and related hazards through research, codes and standards, technical services, and public education. Many of NFPA’s Codes and Standards provide the basis for model building code requirements or actually become a part of these codes. New concepts and other changes in various NFPA Standards are usually adopted by the several model building codes during the code review and revision process. The codes that affect fire dampers, combination fire smoke dampers, and smoke dampers are NFPA 80, 90A, 90B, 92, 101, and 105. California State Fire Marshal (CSFM) The office of State Fire Marshal requires products to go through an approval, testing, and listing process for California. The CSFM listing service provides building authorities, architectural and engineering communities, contractors, and the fire service with a reliable and readily available source of information. FM Global FM Global manages a non-profit research and testing organization which tests and provides approvals for building products to help minimize losses in buildings they insure. FM approved products meet rigorous property loss prevention testing and certification standards. This approval gives the building owner an edge on receiving and maintaining advantageous financing and insurance rates. AMCA The AMCA Certified Rating Program seal assures you that a product line has been tested to the appropriate AMCA standards in accordance with a legal license agreement and that the manufacturer’s cataloged certified ratings have been submitted to AMCA for approval.

59 Most Commonly Asked Questions

Q. Are pneumatic actuators available on smoke and combination ﬁre smoke dampers? A. Smoke and combination fire smoke dampers are available with pneumatic or electric actuators (internal or external mount). Reference: Actuator Selection, page 27

Q. Does the smoke and combination ﬁre smoke damper actuator have to be factory mounted by the damper manufacturer? A. Yes. The 7th Edition of UL 555 and 4th Edition of UL 555S require all actuators on smoke and combination fire smoke dampers to be factory mounted. Reference: Smoke Dampers Installation, page 24

Q. Are there any specific sleeve gauge requirements for combination fire smoke damper installation? A. Sleeve gauge or thickness requirements depend on damper size and the type of duct-to-sleeve connections used. Reference: Sleeve Requirements, page 10

Q. How much space outside the damper sleeve is required to accommodate the actuator installation? Can the actuators be installed inside the sleeve to eliminate external space requirements? A. Clearance requirements for externally mounted actuators vary with actuator type. Enough space should be provided to allow for connection of wiring or piping and the replacement of the actuator and/or control components. If clearance is potentially a problem, the damper manufacturer should be contacted for specific clearance requirements. Installing the actuators internally should be considered only as a last resort, as it creates wiring/piping and service difficulties.

Q. How should combination ﬁre smoke dampers be installed? A. Combination fire smoke dampers must always be installed in accordance with the manufacturer’s installation instructions. References: Fire Dampers Installation, page 9 through 12 Smoke Dampers Installation, page 24 Combination Fire Smoke Dampers Installation, page 32 through 33

Q. Is there any ﬁre, smoke or combination ﬁre smoke dampers that can be used in corrosive environment applications? A. Greenheck has Severe Environment dampers that are constructed out of 316 stainless steel for this application. Reference: Damper Model Definition, page 56

Q. When do I use a ceiling radiation damper versus a ﬁre damper? A. Both dampers are intended to protect openings in horizontal fire barriers. A fire damper is required in a fire rated wall, floor or ceiling or partition when it is penetrated by air ducts or other air transfer openings. A ceiling radiation damper, according to the 2015 IBC (International Building Code). should be used in the following situations: 1. A ceiling radiation damper installed where a duct penetrates the ceiling of a fire resistance rated floor/ ceiling or roof/ceiling assembly. 2. A ceiling radiation damper installed at the ceiling line where a diffuser with no duct attached penetrates the ceiling of a fire resistance rated floor/ceiling or roof/ceiling assembly. Reference: Ceiling Radiation Dampers, page 42 through 44

60 Inspection, Maintenance and Testing

Inspection and Testing Once a building is commissioned, the dampers are required to be inspected and tested one year after installation. After one year, the dampers are inspected and tested every 4 years, except in a building containing a hospital, the frequency is every six years per NFPA 80 and NFPA 105. Dampers are part of the smoke control system and are required to be tested along with the system. Per NFPA 92, the smoke control system is inspected and tested: • At least semi-annually if it’s a dedicated system • At least annually if it’s a non-dedicated system The damper actuator shall be inspected and cycled per the manufacturer’s recommendations. Maintenance Dampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary, use mild detergents or solvents. If lubrication is desired for components such as axle bearings, jackshaft bearings, and jamb seals, do not use oil-based lubricants or any other lubricants that attracts contaminants such as dust. If the damper and/or the actuator are not operable, repairs shall begin as soon as possible.
