CURTAIN TYPE FIRE DAMPERS

Transcription

1 URTAIN TYPE FIRE urtain Fire Damper Basics Definition of a Fire Damper: The National Fire Protection Association (NFPA) Standard 9A defines a fire damper as "a device, installed in an air distribution system, that is designed to close automatically upon detection of heat, to interrupt migratory airflow, and to restrict the passage of flame." Although curtain fire dampers restrict flame and airflow passage as described in the NFPA definition, they are virtually transparent to heat and therefore ineffective for use in openings in fire-rated ceiling assemblies. See eiling Damper Basics, on page 3, for more details. Types of urtain Fire Dampers urtain type fire dampers are generally available in three configuration as follows: TYPE 'A' TYPE 'B' TYPE '' D Blades and frame in the airstream. Blades out of the airstream; ith blades out of airstream, provides better free area and resulting pressure drop characteristics than Type 'A', especially on smaller size dampers. Blades and frame out of the airstream; used mainly for transitioning to round or oval duct. Provides optimum pressure drop characteristics with blades and frame out of airstream. Openings in vertical fire separations ie: walls and partitions, require a vertical mount fire damper (duct runs horizontally). Gravity causes the blades to drop closed (static rated dampers). Openings in horizontal fire separations ie: floors, require a horizontal mount fire damper (duct runs vertically). orizontal mount fire dampers utilize springs to pull the blades closed. Dynamic rated fire dampers utilize closure springs in both vertical and horizontal applications to ensure the blades close fully under airflow conditions. Static Rated vs. Dynamic Rated Fire Dampers: Static fire dampers were designed for use in VA systems that shut down (fans off) in the event of a fire alarm. They have not been tested to ensure closure while air is moving in the duct. Dynamic fire dampers have been tested under specific airflow and static pressure conditions in order to ensure that the damper will close in today s VA designs that utilize 'fans on' smoke management systems. See Dynamic Fire Damper Selection Procedures in this section. Generally, a dynamic rated damper can be used in both static (fans off) or dynamic (fans on) type systems, but a static rated fire damper can only be used in a 'static' system (fans shut down during alarm). Did You Know?... Fire dampers must be mounted in a steel sleeve. The damper/sleeve assembly is held in place in the wall, partition or floor by use of retaining angles on each side of the wall etc. Ductwork shall connect to the sleeve on either side, as required, providing a connection that can 'break away' should the ductwork fall during a fire. This allows the damper/sleeve assembly to remain in the wall etc., maintaining the integrity of the fire barrier. NFPA 9A requires that fire barriers of less than 3 hours utilize a 1 1/2 hour rated fire damper. Fire barriers of 3 hours or more require a 3 hour rated fire damper. All fire dampers must be installed as per manufacturer s instructions. 9

2 DYNAMI FIRE SELETION PROEDURE Selection Procedure For Dynamic Fire Dampers Underwriters Laboratories Inc. Standard for Safety UL 555 evaluates fire dampers for use as either: (A) Fire dampers for static systems for VA systems that are automatically shut down in the event of a fire or for air transfer openings in walls or partitions; (B) Fire dampers for dynamic systems for VA systems that are operated in the event of a fire. Dynamic Fire Dampers are therefore required to close under airflow. All fire dampers must be labeled to indicate if they are to be used in static or dynamic systems. For dynamic rated dampers, this label must also indicate the maximum rated velocity through the open damper, and the maximum pressure differential across the closed damper. To attain approval for use in a dynamic system, UL Standard 555 requires that test dampers close three times (manually released) against their rated flow and shut-off pressure at ambient air temperature before heat is introduced to cause the fusible link to melt and close the damper one final time. All Manufactured Air Products dynamic curtain type fire dampers have been tested to 2 fpm (1.16 m/s) and 4" w.g. (1 kpa) static pressure. EXAMPLE #1: SINGLE SETION FIRE DAMPER To determine the maximum allowable airflow through the following damper: Type A damper 24" x 24". The maximum rated velocity is 2 fpm. 24" x 24" is 4 sq. ft. (idth in inches x eight in inches divided by 144 = sq. ft.), therefore, maximum allowable airflow is 2 fpm x 4 sq. ft. = 8, cfm. heck the maximum system pressure that could occur against a closed damper. Manufactured Air Products dynamic fire dampers have been tested and are rated to close against 4" w.g. 24" (61) EXAMPLE #2: MULTIPLE SETION FIRE DAMPER 24" (61) To determine the maximum allowable airflow through the following multi-section damper assembly: Type A damper 36" x 32" opening (the assembly will consist of four 18" x 16" dampers); The maximum rated velocity is 2 fpm. 36" x 32" is 8 sq. ft., therefore, 2 fpm x 8 sq. ft. = 16 cfm. This is the maximum allowable airflow that may be passed through the 36" x 32" opening. heck the maximum system pressure that could occur against a closed damper. Manufactured Air Products dynamic fire dampers have been tested and are rated to close against 4" w.g. 32" (813) 36" (914) 1

12 STATI FIRE TINLINE 1 1/2 OUR TINLINE FRAME FOR USE IN STATI SYSTEMS 1 1/2 OUR RATING UL 555 LASSIFIED Models: FDTA Type A FDTB Type B FDT Type Model FDTA The MAP FDT Series Thinline curtain fire dampers are UL/UL approved for use where building codes require the protection of VA ductwork penetrations in walls, partitions or floors that have a fire resistance rating of 2 hours or less. The FDT Series is classified for use only in static "fans off" systems where the VA system is automatically shut down in the event of a fire alarm. The FDT Series Thinline dampers are only 2" (51) deep making them ideal for installation in narrow fire rated partitions, transfer duct openings, behind grilles or in any other application where space is limited. The FDT Series feature corrosion resistant steel frame and blades for lasting performance, and choice of transition styles and factory installed sleeves to suit duct size, making installation fast and simple.
