3 GENERAL PRODUCT OVERVIEW For over thirty years, Nailor Industries has been committed to the development of life safety products such as the 0700 Series Ceiling Dampers. This commitment has helped foster industry standards, as well as provide worry free fire protection solutions that benefit today s building designers, owners and occupants. Approved for use in lieu of hinged door type dampers in UL floor/ceiling or roof/ceiling assemblies, the Nailor 0700 Series provides a fire and heat barrier that has been tested and qualified to the most exacting standards. For square and rectangular applications, Model 07 is available with standard blade construction or low profile blades, Model 07-. Round duct applications are covered by Model 07. Nailor s new Model 070 features a spring loaded curtain design that maximizes free area while providing a low overall profile. Other Series 0700 particulars such as the Adjustable Fusible Link option, ideal for balancing at the grille/diffuser, and Models 07 thru 07, suitable for use in wood truss ceiling assemblies, have been developed to meet specific requirements in today s building systems. MODELS 07, 07-, 07 AND 07 CEILING RADIATION DAMPER FOR SQUARE, RECTANGULAR OR ROUND DUCT Nailor ceiling dampers, or ceiling radiation dampers as they are commonly called, are designed to function as a fire and heat barrier in air duct openings penetrating fire resistive membrane ceilings. Models 07, 07- and 07 are for use in square or rectangular applications and Model 07 is for use in round applications, in lieu of hinged door type dampers in any UL floor/ceiling or roof/ceiling assembly with up to a hour fire resistance rating where air ducts are allowed. Models 07A and 07A Models 07 and 07 MODELS 07A, 07-A AND 07A CEILING RADIATION DAMPER ADJUSTABLE FOR SQUARE, RECTANGULAR OR ROUND DUCT Nailor ceiling dampers with adjustable volume control option are designed to function as a fire and heat barrier in air duct openings penetrating fire resistive membrane ceilings. The adjustable volume control mechanism allows the blades to be adjusted for balancing of airflow through the diffuser. Under fire conditions the fusible link will close the damper, regardless of volume setting. Models 07A and 07-A are for use in square or rectangular applications and Models 07A is for use in round applications, in lieu of hinged door type dampers in any UL floor/ceiling or roof/ceiling assembly with up to a hour fire resistance rating where air ducts are allowed. MODEL 070 CEILING RADIATION DAMPER FOR SQUARE OR RECTANGULAR DUCT The Nailor Model 070 ceiling radiation damper, which functions as a fire and heat barrier in air duct openings that penetrate fire resistive membrane ceilings, is for use in lieu of hinged door type dampers in any UL floor/ceiling assembly with up to a hour fire resistance rating where air ducts are permitted. Model 070 features a specially designed pull across insulated curtain that provides a low overall profile, making it ideal for use in applications where the available duct drop height for installation is limited. The compact curtain design also maximizes free area in the open position. Model 070

4 GENERAL PRODUCT OVERVIEW MODELS 07/07 TERMAL INSULATING BLANKET Nailor Models 07 and 07 Thermal Blankets are designed to insulate the exposed back pan area of a steel ceiling diffuser that may be used in UL Classified floor/ceiling or roof/ceiling assemblies with up to a hour rating. The insulation protects the floor/roof structure above from the intense heat that radiates through the diffuser pan during fire conditions. A thermal blanket is used in conjunction with a ceiling radiation damper that protects the neck opening of the diffuser, to provide complete protection of the opening in the ceiling membrane. Model 07 thermal blanket is for use with 07 ceiling damper models in round neck applications. Model 07 thermal blanket is for use with 07, 07 and 070 ceiling damper models in square neck applications. Models 07/07 Models 07 and 07 MODEL SERIES 07, 07 AND 077 CEILING RADIATION DAMPER FOR WOOD TRUSS CEILING ASSEMBLIES Nailor Models 07, 07 and 077 Ceiling Radiation Dampers have been designed and tested for simple installation in specific UL design wood truss ceiling assemblies. They are UL Classified for use in hour rated UL floor/ceiling design numbers L0 and L, and roof/ceiling design numbers P and P8. Model 07 ships complete with thermal blanket and top inlet round duct connection. Model Series 07 features a factory sheet metal plenum with side duct connection collars. Model Series 077 is designed for side duct connection collars and can be supplied with or without the fiberglass ductboard plenum. MODELS 078, 079, 070, 07 AND 07 CEILING RADIATION DAMPER/REGISTER BOX FOR WOOD TRUSS CEILING ASSEMBLIES Models 078 thru 07 register boxes with integral ceiling dampers have been specifically designed and tested to provide protection and simple installation in specific UL design wood truss ceiling assemblies. Model 078 features a side inlet; Model 079 features a side inlet and is insulated. Model 070 is insulated with a inlet. Model 07 features a top inlet; Model 07 is insulated with a top inlet.

5 CEILING DAMPER BASICS CEILING DAMPER BASICS: Definition of a Ceiling Damper (quoted from NFPA Standard 90A): A device installed to limit radiant heat transfer through an air outlet or air inlet opening in the ceiling of a floor-or roof-ceiling assembly having not less than a hour fire resistance rating. What is the difference between a Ceiling Damper and a standard Fire Damper? In order to comprehend the difference we must first understand some of the theory behind fire-rated ceilings. A fire-rated ceiling s primary function is to protect the structure above it from excessive heat and potential subsequent collapse by providing a fire and heat retardant barrier between the fire area and the structural floor above. Without any openings in the fire-rated ceiling, it would perform as designed by limiting the transfer of heat through the floor above it. Problems arise when we pierce the protective ceiling with big holes to accommodate environmental control devices such as grilles and diffusers. To close these openings should a fire occur, devices called Ceiling Dampers (also commonly called radiation dampers or fire stop flaps) have been developed. If the openings were to remain unobstructed during a fire, generated heat would tend to rapidly flow through in concentration due to a funnel effect created at the openings as the hot combustion gases expand and rise. This EAT FOCUS (CONCRETE SUBJECT TO CRACKING AND EXPLOSION) FIRE RATED CEILING ASSEMBLY FUNNEL EFFECT FIGURE EAT FOCUS (STEEL SUBJECT TO DISTORTION) FIRE AREA focuses the intense heat into the structure area directly above the openings, potentially causing severe structural damage (See Figure ). Ceiling dampers are specifically designed to protect against this phenomenon by firstly, closing the opening to stop any air flow and secondly, by reducing the amount of heat that is conducted and, most importantly, radiated through the device. This is most important, as a regular fire damper although fine for stopping flame and migratory air flow, is virtually transparent to heat and therefore ineffective in this application. Ceiling Dampers are tested by Underwriter s Laboratories to the strict criteria of UL C, Safety Standard for Ceiling Dampers which includes tests for:. Fire Endurance. Closing Reliability. Dust Loading. Salt-Spray Exposure. Spring Closing Force (if applicable) Ceiling Dampers are not assigned hourly ratings themselves, but rather are listed for use as a component in an assembly designated for use in fire resistance assemblies having specific hourly ratings. All Nailor Ceiling Dampers are classified (Category CABS) for use in any UL floor/ceiling or roof/ceiling restrained or unrestrained type assembly with up to a hour fire resistance rating.
