FSD-C Series

Single Blade Combination Fire and Smoke Dampers – Introduction

Introduction

The FSD-C Motorised Failsafe Single Blade combination Fire and Smoke Damper has been designed specifically for installations where space is at a premium and installation within the fire separation is not feasible.

The FSD-C Single Blade Fire/Smoke Damper provides greater free area than comparable sized conventional multi blade fire/smoke dampers.

The installation plate, with its engineered installation perforations, acts as a template to allow the marking of the fixing positions on the surface structure to which the plate will be affixed, allowing for a quick and efficient install.

FSD-C Features and Benefits

• Tested and certified installation variants of the FSD-C are available for both blockwork and stud partitions.

• All BSB tested installation methods give at least a E90 classification.

• Unique blade construction.

• Halogen free LSF cable

• Exceeds the requirements of EN1366-2

• Reduced commissioning time

• Thermal fuse replaceable external to the duct.

• Test switch integral to the thermal fuse allowing the damper to be tested locally and individually.

• LED indication that power is available to the actuator and the thermal fuse is intact.

• Installation plate with template location holes to allow easy installation.

Introduction

What is a fire damper and why might they be needed?

The FSD-C Series Single Blade Circular Fire Damper is designed to stop the spread of fire through ducts passing through walls and floors.

The product range has many features and options to meet the requirements of specifiers, contractors, local and national authorities.

Dampers are available to suit both low/medium and high velocity applications.

What are the ‘E’ and ‘ES’ classifications?

To achieve the classifications to EN13501-3, fire dampers and fire and smoke dampers shall be tested to EN1366-2 and a 300Pa pressure difference is applied across the damper. During the fire test period, the integrity of the seal between the damper and the structure shall not have any gaps larger than 150mm x 6mm. There shall not be any sustained flaming. The largest size of damper to be manufactured for sale as a single section shall be fire tested.

E = Integrity

The maximum leakage permissible at 300Pa corrected to 20°C is

360m 3 /hr/m 2 (100 l/s/m 2 ) throughout the fire test period.

ES = Integrity with Smoke Leakage Performance

The maximum leakage permissible at 300Pa corrected to 20°C is

200m 3 /hr/m 2 (55.5 l/s/m 2 ) at ambient prior to the fire test and throughout the fire test period. In addition, for the ES classification to be attained, the smallest damper must also meet the 200m 3 /hr/m 2 maximum leakage with a 300Pa pressure across the damper. (This is equivalent to just 0.55 l/s on a 100x100 damper)

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-C 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.

FSD-C Series

Single Blade Combination Fire and Smoke Dampers – Introduction

The FSD-C Series Range

The BSB FSD-C series is available in the following case diameters:

FSD-C100 - 100mm dia.

FSD-C125 - 125mm dia.

FSD-C150 - 150mm dia.

FSD-C160 - 160mm dia.

FSD-C200 - 200mm dia.

FSD-C250 - 250mm dia.

FSD-C300 - 300mm dia.

FSD-C315 - 315mm dia.

Thermal Fuse

The BSB PML24-TF and PML230-TF actuators incorporate a thermal fuse (TF), which operates at 72°C.

The thermal fuse will be factory fitted to the FSD-TD series damper a quick visual check as standard, unless requested otherwise.

The thermal fuse has a green LED indicator which provides a quick visual check that the fitted actuator is receiving power and that the thermal fuse is intact.

A momentary push test switch is included within the thermal fuse head for periodic testing of the damper.

For reasons of safety the thermal fuse is designed to operate only once upon reaching the activation temperature. Cutting the cable to the thermal fuse with the power on will trip an electrical fuse within the actuator, rendering it inoperable.

Damper Control Panels

BSB offer two alternative damper control panels when monitoring and controlling dampers. The Electro Mechanical

System and the Fully Addressable System. Please contact our sales office or consult relevant product brochures for further information.

FSD-C Series

Single Blade Fire and Smoke Dampers – Product Testing

FSD-C in Blockwork Wall

Tested to BS EN 1366-2

The FSD-C series damper has been tested both ways, with access side inside the furnace and nonfurnace side.

• Tested to BS EN 1366-2 and BS EN 13501-3

• E180 integrity classification.

• ES120 integrity classification.

• ES90 horizontal concrete floor.

• Complies with classes A, B & C of DW144.

• Surpasses minimum requirements on case leakage

• Surpasses minimum requirements on blade leakage

VIEW FROM INSIDE FURNACE

Test Conclusions:

The FSD-C combination Fire and Smoke Damper satisfied the requirements of BS EN 1366-2 and BS EN 13501-3 achieving the lowest closed blade leakage of any damper within its class.

Dampers were tested affixed to the inside of the furnace wall and also to the external wall of the furnace with the damper closed blade being fully exposed to the furnace rapid rising temperature.

The achieved ES classification ensures that in a fire condition the non fire side is fully protected (from radiated heat) for the achieved period, providing vital time for the emergency services to respond, ensuring safe passage of escape and protection of contents.

Maintenance Notes

FSD-C Series combination Fire and Smoke Dampers are designed for normal dry filtered air systems. A programme of planned inspections should be carried out to include full operational checks, correct interface with, and function of, any control systems, cleaning and light lubrication.

As a guide, this should take place annually. Please refer to

BSB Operating and Maintenance instructions.

Reference should be made to BS 9999 for more information.

Records of damper installation and position shall be kept.

Records of the condition of the dampers and their functionality/repair etc should be kept as these products come under the requirements of the Regulatory Reform (Fire safety)

Order (RRFSO).

These inspection and maintenance programmes may need to be repeated more regularly if the dampers are exposed to inclement/dusty conditions or fresh air intakes and the frequency of such checks should be developed based on site experience.

FSD-C Series

Single Blade Fire and Smoke Dampers – Cleats

Rotatable Easy Bend Cleats

The optional Rotatable Cleat Easy Fix System will be supplied factory fitted to the FSD-C Series dampers.

The installation plate should be fitted to the fire separation barrier to ensure test conformity is maintained. The Easy Bend Cleat is available factory fitted four per plate. The cleats should only be used where the fire separation element is not yet in place, offering a temporary installation support. The cleats must not be the sole independent method of supporting the fire damper.

The cleats can easily be bent out using a flat head screwdriver.

Supporting drop rods are used in the normal way.

The cleats can be rotated through 90 degrees to suit handle position where the damper requires to be installed with the handle either left, right, top or bottom giving full flexibility during installation.
