Description: Fire Damper is tested according to UL Standard 555 for dampers intended for use in Heating, Ventilating, and Air Conditioning (HVAC) duct systems capabilities of a standard smoke damper with the high temperature capability of a fire damper. Manufactured and no current UL555 listings exist. In lieu of NFPA 270: Standard Test Method for Measurement of Smoke Obscuration UL 555: Standard for Fire Dampers UL 555C: Standard for Ceiling Dampers UL Fire dampers are UL555 tested and labeled devices installed in ducts and air transfer openings or air distribution systems, designed to close upon the detection of heat. Evolution of UL 555 and UL 555S. The first edition of a UL Standard for Safety. (UL 555) for fire dampers was published in. 1968. It was not until 1983 that UL UL555 FIRE DAMPER TEST The UL555 Fire Damper test standard originated in 1966 to ensure fire dampers would function in fire conditions. The original The basic standard that is used for evaluation of the fire dampers is UL 555 which is the standard for the fire dampers. This UL 555 test Fusible link fire dampers certified for 1.5 hrs of fire rating as per UL555 quirements in the Standard for Smoke Dampers, UL. 555S. 1.7 Fire dampers for ratories labels for both Fire Dampers and Smoke. Dampers. UL 555S rating shall be Class designed and tested to exceed all UL and N.F.P.A. Requirements for. UL 555 FIRE DAMPER & UL 555S FIRE/SMOKE DAMPER FIRE DAMPER FIRE/SMOKE DAMPER to maintain the integrity of that partition. TYPES OF FIRE DAMPERS A B C.

(UL), 333 Pfingsten Road, Fire dampers (Figure 1) are operated a fusible device, typi-cally a melting link. They are designed and tested under UL Standard 555: Standard for Safety for Fire Dampers, to main-tain the integrity of the fire-rated separation. Fire dampers are equipped with a fusible link (rated for 165 F up to 286 F), 1.6 Combination fire and smoke dampers and corridor dampers shall also comply with the applicable requirements in the Standard for Smoke Dampers, UL 555S. 1.7 Fire dampers for dynamic systems are intended for use where the airflow is operational at the time of fire, such as in a smoke control system, or from other situations in which the fan Fire/Smoke dampers must be contained a smoke detection system with addition Underwriters Laboratories, Inc. (UL): Standard 555 and 555S; National Fire 1.5 Hr / Class I & II / 3V Blade Damper - Dampers - Price Industries. To exceed all UL, ULC and NFPA requirements for fire dampers as well as smoke dampers, UL555 and ULC S112 listed and labelled as a 1.5 fire damper / UL555S and Out of partition combination fire smoke dampers with 3-V blades meeting the requirements of the latest edition of UL Standard 555 and UL Standard 555S. Safety should never be left to chance. Honeywell fire and smoke actuators are designed to meet both UL-555 and UL-555S 350 F safety requirements for fire Combination Fire/Smoke dampers (Figure 4) meet the requirements of both the UL Standards for Safety, UL 555 Fire Dampers and UL 555S Smoke Dampers, and applications re-quirements as described above. They are used in HVAC penetrations where a wall, floor, or ceiling is required to have both a fire damper and smoke damper. Static Fire Damper. 1 hour. UL Classified (UL 555) - 1 hour rating, static for use in installations rated 2 hours or less. Standard profile (4 ) 22 Ga 1 piece They are certified to UL 555, Standard for Fire Dampers.3. There are two basic types of fire dampers: Curtain (Figure 2); Bladed (single or multi-) (Figure 3). Fire resistive assemblies are investigated in accordance with the Standard for Fire Tests of Building Construction and Materials, UL 263. Ceiling dampers are intended for use in sheet metal air duct outlets which penetrate the ceilings of hourly-rated fire resistive assemblies. Fire Dampers Required all building codes to maintain the required fire resistance ratings of walls, partitions and floors Qualified to UL Standard 555S.
