Volume Control Application
The FSD-C Fire/Smoke damper has the facility to additionally allow air balancing and the setting of
the blade position during commissioning via the fitted actuator using the “damper open set position
adjustment”.
Dampers can be set so that the open blade position is restricted between 30° and 90° (60° range)
whilst still retaining fail safe spring closure in an alarm condition or power failure.
Installation Plate
The installation plate allows the damper
to be fixed into place from one side only
with no infill material being required.
Use either of the two appropriate 5mm dia.
corner fixing holes and all of the 5mm dia.
mid span fixing holes to secure the plate into
position.
(Note: Option without installation plate
is not CE marked)
Thermal Fuse
Thermal Fuse rated at 72°C
is factory fitted and is replaceable
external to the damper case.
The thermal fuse is fitted with a
green LED indication light which
provides a quick visual check that
the actuator is receiving power
and that the thermal fuse is
operational. A manual sprung test
switch for periodic testing of the
damper is also included.
Blade Seal
(patent pending)
Layered glass woven sheets and
central intumescent disc to a
patented design that allows the
blade assembly to be of minimal
thickness, thus minimising
pressure loss, providing an
effective seal to comply with
EN 1366-2 achieving ES
classification.
Blade
Galvanised 1.2mm one piece
circular steel discs either side of
the patented seal design
providing a 5mm thick assembly
affixed by blade brackets to the
drive spindle. Grade 430 stainless
steel blade option available.
PMC-TF Actuator
The PMC-TF actuator is a
spring return actuator that
additionally allows the
setting of the blades during
commissioning of the system
from fully open 90° to 30°
from closed. The PMC-TF
actuator is available as 24
volt or 230 volt.
Case
Galvanised mild steel to BS EN 10346 DX 51D Z275
0.6mm thick for 100mm dia. to 250mm dia.
