Periodic Test *Within BS9999 its notes that dampers installed in dirty/dusty environments should be tested more regularly in line with the pollution encountered. After that one year mark, fire dampers must then be tested and inspected every four years except for hospitals which have a six year frequency. Fire walls need fire dampers with no exception, while the fact that smoke damper is needed should mean that the same wall is defined as smoke bareer. This has opened a discussion about whether fire dampers are necessary in our building, with the contractor insisting they werent needed in the first place. Where is a fire damper required? Basically I have an air handling unit serving a corridor with a duct. About Richard Norman Clearance requirements for damper sleeves within a wall opening . Visually inspect the link to verify its not damaged. Operational Test 2. . 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. If the air duct is an air transfer opening (meaning it is not fully ducted) at the fire-rated barrier, then the duct needs a fire damper where other openings are required to be protected as well. Repeater panel, as the name suggests repeats or clones all information and status of the Fire alarm system observed by the main fire alarm control panel. Repeater panels are installed at remote locations or multiple locations to enable the facility managers to monitor the fire alarm system from a different or far off location. Protecting people and property. If fire dampers are in use, one of these measures will be regular fire damper inspection and testing undertaken by a competent person.

This should be detailed by the facility managers. 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. And they are required at some, but not all penetrations of rated floor assemblies and shaft enclosures. Now we cant pass the inspection because the inspector needs to see the dampers. However, two-hour fire-rated barriers do require fire dampers in fully ducted HVAC systems. Fire dampers should be tested under 3 activities, with the code requirements listed below: 1. The damper frame must not be penetrated by any foreign objects that would affect fire damper operations. The NFPA 105 requires that each fire or smoke damper should be inspected one-year post-installation. Regular fire damper inspection should be executed every four years following the initial inspection. And they are required at some, but not all penetrations of rated floor assemblies and shaft enclosures. ( (6 mm) minimum) b. They are needed in all air transfer openings (non-ducted) in rated walls, regardless of the rating. Minimum inch per linear foot (10mm per linear meter) of damper both dimensions. They are used in HVAC penetrations where a wall, floor, or ceiling is required to have both a fire damper and smoke damper. 5.4: Fire Dampers, Smoke Dampers, and Ceiling Dampers ratings and acceptance testing Chapter 6: Controls Chapter 7: Acceptance Testing SPS 364.0607 (4m): Smoke dampers are not required in Group I2 duct penetrations of smoke barriers in fully ducted HVAC systems. Generally, fire dampers are required where air ducts penetrate walls that are rated for 2-hours or more. In vents, you can usually identify the damper by looking through and seeing shutters and a fusible link. And they are required at some, but not all penetrations of rated floor assemblies and shaft enclosures. This is usually required on an annual basis, or more frequently in specific conditions, such as areas with high pollutants or dust. Where an assembly is required to have both fire dampers and smoke dampers, combination fire/smoke dampers or a fire damper and smoke damper shall be provided. 1. To tell if you have a firewall, you can usually look at a doorway to see a fire rating on the inside jamb. IMPROPER FIRE DAMPER INSTALLATION Background floors or partitions that are required to have a fire resistance rating. Fire dampers can be set into masonry, floors or walls, or built into bulkheads and steel decks. Replace link as necessary. Fire dampers are required in the following locations: Ducts and air-transfer openings penetrating walls or partitions having a fire resistance rating of 2 or more hours, Ducts and air-transfer openings penetrating shaft walls having a fire resistance rating of 1 or more hours, At Dust Spares, we stock a variety of fire dampers for all types of ductwork, from 100mm to 300mm in diameter. IT IS NOT NECESSARY. Never install a fire damper without the proper UL approved fusible link in place. In general a fire damper works when heat from a fire causes the normal temperature of a room to rise to approximately 165 degrees Fahrenheit i.e. The main design considerations are: Free Area, Flow and * Indicates required field Name * Email * Download Now At least two documents address the use offirestop materials in annular spaces that surround fire dampers. For mechanically ventilated battery rooms, the ventilation requirement shall be based on Cl.7.1.15d., or 6 air changes per hour, whichever is higher. Generally, fire dampers are required where air ducts penetrate walls that are rated for 2-hours or more. Why are fire dampers required? g. A fire-rated partition is a continuous membrane with a specified fire rating. f. No fire damper shall be provided in the essential ventilation system and ducts passing through other compartments shall have 2-hr fire resistance rating. To maintain the required fire rating to walls, partitions, barriers, or floors when ducts or other air transfer openings penetrate them, building codes and regulations require that fire dampers are installed to provide separation, in the event of a fire, between compartments restricting it spreading. Fire/Smoke Dampers All exposed moving parts of the damper must be dry lubricated as required by the manufacturer. The damper must not be blocked from closure in any way. A fire damper or any fire suppression device is a serious piece of equipment designed to reduce the loss of life and property. They are needed in all air transfer openings (non-ducted) in rated walls, regardless of the rating. A smoke damper is required at each duct penetration of a smokebarrier.Exceptions: Steel ducts limited to one smoke compartment I-2 Occupancy: Fully ducted system, area protected with quick response sprinklers Smoke barriers are also automatically one-hour fire partitions, so go back a few slides to determine a possible fire damper requirement. Dampers are required for any penetration through a firewall. It may also carry a fire rating. The International Building Code (IBC) states that dampers must be installed in air movement systems to allow for those sheltering in place, exits, and exit access areas to remain safe and smoke-free in emergencies. Fire Dampers From Dust Spares. Do not lift damper using blades.

Smoke damper drawing symbol If you want to draw a smoke damper or find it on a drawing, it would usually be shown by this symbol: After the model of the fire damper that is required has been determined there will be several configuration options to Fire dampers impose some resistance to air flow and therefore must be considered by the designer in determining the required flow rate (cfm) to each space. They are needed in all air transfer openings (non-ducted) in rated walls, regardless of the rating. Fire dampers, smoke dampers, combination fire/smoke dampers, ceiling radiation dampers and corridor dampers shall be provided at the locations prescribed in Sections 607.5.1 through 607.5.7. A smoke partitions primary objective is to prohibit the passage of smoke. Necessity of installing fire damper does not have any relation with supply or return ducts, As fire dampers are installed on both according to the requirement (Ducts passing through any enclosure which is build by fire rated materials). The fusible link which is attached to the damper melts causing the dampers' door to close. The requirement for duct detection kicks in at 2,000 ft 3 /min. Generally, fire dampers are required where air ducts penetrate walls that are rated for 2-hours or more. Lets first look at some fire damper specifics.
