Fire & Smoke Dampers
What is a fire damper and why might they be needed?
A fire damper is a device for use in heating, ventilation and air-conditioning (HVAC) systems at fire boundaries to maintain compartmentation and protect means of escape in case of fire.
The BSB FSD-TD series of fire and smoke dampers are carefully engineered to fulfil the above and to have the advantage of having reduced smoke leakage characteristics. They can respond to a smoke alarm input as well as having a failsafe thermal fuse.
Integration with systems such as BSB’s smoke control panels will give this functionality.
This means that specifiers can safely select the BSB FSD-TD series for use in HVAC ductwork systems to safely fulfil the regulations in the form of Approved Document B (ADB) to protect both escape routes and areas with sleeping risk, as well as standard compartmentation.
Fire damper testing is generally undertaken to BS EN 1366-2 and for a fire damper to fulfil the requirement to protect escape routes and areas with sleeping risk they must be classified ES to BS EN 13501-3.
Fire dampers should be installed as tested.
Some applications (fan off) allow the use of tests undertaken to BS 476-20/22 and this is also allowed worldwide in areas outside of the EU. Test reports showing testing to EN 1366-2 should be acceptable to meet the requirements of BS 476-20/22, but the reverse is definitely not the case and no classifications are available.
However, as a word of caution, in whichever case, the correct model must be selected, to match fire resistance time with installation method and with the supporting construction (wall or floor).
To ensure that all testing and assessments are traceable back to initial fire test reports, the BSB FSD-TD series is product certificated by the Loss Prevention Certification Board (LPCB). This means that in addition to normal BS EN ISO 9001 compliance, the product is also checked to ensure that same product is being manufactured that has been tested or assessed.
BSB have a policy of continued testing and product certification to try and provide as broad a number of installation methods as possible.
BSB also follow regulation and standards development very carefully to provide input on changes and to be able to pass on relevant information to designers, specifiers, building control authorities (BCA's) and installers.
Features and Benefits s
• The majority of the FSD-TD product variants are covered by third party Loss Prevention Certification Board (LPCB) product certification. This represents both full BS EN ISO 9001 quality compliance and a guarantee that the products are fully representative of those actually tested.
• Tested and certified installation variants of the FSD-TD are available to cover masonry walls, dry walls, batt walls and floors. These cover the majority of applications/supporting constructions that are required to maintain compartmentation and protect escape routes and areas with sleeping risk.
• All BSB tested installation methods give at least a ES120 (E120S) classification, usually only limited by the wall construction used. This is extended to ES240 (E240S) when installed using a HEVAC frame in a masonry/blockwork floor or wall.
• Sleeve and angle methods, HEVAC frame methods, cleat and drop rod methods and batt infill methods are available.
• Some rarer installation applications are covered by assessment/test information to BS 476-20/22.
• Compatible to B.M.S. and bespoke control systems
• Minimum size 100 x 100 (not adapted from a larger size by reducers) available for space saving.
• Single section size 1000 x 1000, available from the smallest size up to this in millimetre increments.
• Multi-section configurations are available to specific customer requirements, but will be subject to BCA approval.
• No duct sleeve, again giving space savings over other models and savings on transport volume
• Standard construction is a fully welded galvanised steel case, which gives a casing leakage that complies with Class C ductwork leakage specifications
• Blades are manufactured from 430 stainless steel as standard. Blade seals are not required on the FSD-TD dampers to meet the requirements of EN1366-2 to meet the ES classification.
• Blades have folded safe-edges to aid site safety
• Other combinations of galvanised mild steel, 430 and 316 stainless steels for the blades and case are available to specific customer requirements
• All blade and motor connecting drives are removed from the airstream and are fully enclosed. This gives both increased free area through the damper and protection to the mechanisms
• Electrical Actuators (24VAC/DC, 230VAC,) have a less than 60 second motoring time. They have multi-position adjustability and, being remote from the duct, allow space savings.
• Pneumatic Actuator (5.6 bar) have a less than 3 second opening and closing time. They have multi-position adjustability and, being remote from the duct, allow space savings.
• All factory fitted actuators are tested prior to despatch (NOTE: The thermal fuse needs to be fitted/installed through the duct wall by the customer when the damper is installed)
• Actuators may be supplied separately to the dampers for site fitting by others to suit customer specific requirements
• The FSD-TD range is fully compatible with the BSB range of smoke control panels, building management systems (BMS) and other bespoke control systems
• The BSB FSD-TD has a strong and robust design to both meet the exacting fire testing requirements and be resilient to site handling. This is supported by sound production techniques which result in a quality product
• All the above, supported with BSB's enviable delivery performance, provide an unbeatable combination
