BSB FSD-C Series Manual page 3

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.
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.

Typical Tender/Specification Text
The BSB FSD-C combination Fire and Smoke Damper
shall pass the test requirements stated in EN 1366-2.
For maintenance of the integrity of compartmentation the
fire damper shall have an E classification to EN 13501-3.
The damper shall have an ES classification complying with
EN1366-2 and EN 13501-3 and have a minimum E120 and
ES120 rating.
For the protection of escape routes and areas with sleeping
risk, the FSD-C fire/smoke damper should be used. Please
refer Approved Document B (ADB).
The single blade layered design shall be held open against
the constant force of the fitted actuator that is released to
spring closed via the activation of the fitted thermal fuse
rated at 72°C.
The damper actuator assembly shall be safely tested and
released closed externally to the damper without the need
for specialist tools.
The fire damper body shall be fully welded to meet the air
tightness test requirements of HVCA specification DW144
to class A B & C to a maximum of 1000Pa and comply with
EN1751.
The closed blade shall meet the air tightness test
requirement of BS EN 1751 Class 2.
The BSB FSD-C combination Fire and Smoke Damper
shall have a tested or assessed installation method that
matches the requirement of the supporting construction.
