Introduction
What is a fire damper and why might they be needed?
The SD-C Series Single Blade Circular ire 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
360m3/hr/m2(100 l/s/m2) throughout the fire test period.
ES = Integrity with Smoke Leakage Performance
The maximum leakage permissible at 300Pa corrected to 20°C is
200m3/hr/m2(55.5 l/s/m2) 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 200m3/hr/m2
maximum leakage with a 300Pa pressure across the damper. (This is
equivalent to just 0.55 l/s on a 100x100 damper)
ire 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 SD-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.
Introduction
The SD-C Motorised ailsafe Single Blade combination ire
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 SD-C Single Blade ire/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.

Thermal use
The BSB PML24-T and PML230-T
actuators incorporate a thermal
fuse (T ), which operates at 72°C.
The thermal fuse will be factory fitted to
the SD-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.
or 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.
The SD-C Series Range
The BSB SD-C series is available in the following case
diameters:
SD-C200 - 200mm dia.
SD-C250 - 250mm dia.

Test Conclusions:
The SD-C combination ire 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
SD-C Series combination ire 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 ( ire safety)
Order (RR SO).
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.

Rotatable Easy Bend Cleats
The optional Rotatable Cleat Easy ix System will be supplied
factory fitted to the SD-C Series dampers.
The installation plate should be fitted to the fire separation barrier

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.
