Features
Inter-Connecting
Mechanism
All Ductgard units are
driven using a unique,
patented, interconnecting
rack mechanism as
illustrated. This
intrinsically simple
mechanism has been
ingenuitively applied to
the damper and its
characteristics ensure that
all units can operate
repeatedly with faultless
precision. Added benefits
include reliability,
durability, speed and low
torque operating
conditions.
Interlocking Blade
Operation
The Stainless Steel
Blades featured on the
Ductgard units,
incorporate a fishtail edge
detail which, with the help
of the precision single
rack operation, enables
the blades to close and
interlock extremely tightly.
This provides a tough,
effective screen against
smoke and flames for its
maximum 4 hour rating.
Stainless Steel
Edge Seals
These provide effective
barriers to cold smoke
penetration and allow the
blades to expand under
fire conditions minimising
leakage at all times
1.2mm welded duct to damper
extension fitted as standard to

Description
Mode 5 is a fully automatic type of smoke and
fire damper and operates on the basis of fail
safe closure with automatic reset. It has been
designed to close in smoke and fire conditions
upon signal from a fire detection system or in
the event of an electro thermal fusible link
separating at a pre-determined temperature
(72°C standard).
Operation
Mode 5 is fitted with a square drive spring return
motor which will hold the damper open for as
long as the supply voltage is available.
Interruption of this supply will cause controlled
damper closure by way of the motors spring
return operation. In addition however, the
damper is also fitted with an electro thermal
fusible link which will separate at a pre-
determined temperature (72°C standard) and
close the damper irrespective of motor position.
All Mode 5 units are also fitted with a control
box which is situated on the dampers ductwork
extension and houses the integral PCB, status
indication L.E.D. and test facility. The test key
facility allows local checks to be made on the
damper operation.
The L.E.D., provides the following diagnostic
checks:-
GREEN DISPLAY:- Power supply ON, unit set.
RED DISPLAY:- Power supply ON, but unit in
fail safe mode.
NO DISPLAY:- Power supply failure, unit in fail
safe mode.
The control box also provides an interface for
remote status indication, smoke detectors and
RCP control (see page 11 and 12).
Control Options
A- 24v DC Power Supply
B- 240v AC Power Supply
Re-Set Procedure
Provided the fusible link is intact and the remote
or local test facility is not being utilised the
damper will automatically reset after an
interruption of the supply voltage. The motor will
take approximately 80 seconds to fully open the
damper.
The LED indicator and test facility are housed in
a control panel mounted on the ductwork
connection sleeve. Fully assembled prior to
despatch they require only the external electrical
wiring connections to be made on site.
Mode 6 performs in exactly the same manner as
the Mode 5 except that the operation is reversed
and the unit is fail safe open. The motor sets the
unit in the closed position and the unit will only
open in the event of a signal from the fire
detection system, separation of the thermal
fusible link or operation of the key test facility.

Description
Mode 9 is a fully automatic type of smoke and
fire damper and operates on the basis of fail
safe closure with automatic reset. It has been
designed to close in smoke and fire conditions
upon a failure of the supply voltage to the motor
or in the event of an electro thermal fusible link
separating at a pre-determined temperature
(72°C standard). Volt free microswitches are
included as standard.
Operation
Mode 9 is fitted with a spring return square drive
motor which will hold the damper open for as
long, as the supply voltage is available.
Interruption of this supply will cause controlled
damper closure by way of the motors spring
return operation. In addition however, the
damper is fitted with an electro thermal fusible
link which will fail at a pre-determined
temperature (72°C standard) and close the
damper irrespective of the status of the motor.
An integral test pushbutton on the electro
thermal fuse housing allows for the local testing
of the damper operation.
Motor Control Options
A: 24V AC or DC supply.
B: 240V AC supply.
Note: All options are complete with position
microswitches as standard.
Re-set Procedure
Provided the fusible link is intact the damper will
automatically reset after an interruption of the
supply voltage to the motor. The motor will take
approximately 80 seconds to open the damper.
The spring return motor and terminal box (if
fitted) are mounted on the ductwork connection
sleeve. Fully assembled prior to despatch they
require only the external electrical connections
to be made.
Mode 10 performs in exactly the same manner
as the Mode 9 except that the operation is
reversed and the unit is fail safe open. The
motor sets the unit in the full closed position and
the unit will only open in the event of a an
interruption of the supply voltage to the motor or
separation of the thermal fusible link.

HEVAC Installation Frame HVC 6/5/85
The installation frame is designed to be factory assembled
on to a fire damper. This frame will under fire conditions
allow the damper to expand without distortion. Upstand
flange webs with fixing tabs built into the surrounding
structure ensure that the complete assembly will be retained
within the structural opening.
A factory assembled installation frame may be provided and
fitted to a double module assembly not exceeding an overall
size of 1524 x 1016mm (split on the larger dimension).
Adjacent frame assemblies must be separated by builders
work of a minimum distance of 225mm (between installation
frame upstand flanges unless approval has been previously
obtained from the appropriate authority).
Where two fire dampers, or two double module assemblies
are mounted in series to form a factory assembled four hour
unit, each damper or double module assembly comprising
the unit shall be provided with its own installation frame so
as to allow each individual damper or double module
assembly to expand under fire conditions.
The work shall be carried out to the satisfaction of the
appropriate authority which in inner London, will be the
District Surveyor. Any deviation must have similar approval.

Test Data Fire Tests
All fire tests were conducted by the Warrington
Research Centre to BS476 Part 20 1987.
This standard describes the performance of
structural elements under fire conditions. It was
decided to mount the unit in the face of a 3m sq.
vertical furnace, and subject it to the test
described.
Test Description
The test specimen was fixed to a brick wall built
within a framed lined with refractory concrete at
the test laboratory. This frame was then
mounted such that the complete assembly
formed the front vertical face of the gas fired
furnace. The furnace was provided with
thermocouples arranged such that they were
evenly distributed over the exposed face of the
test construction and with their hot junction
100m from the nearest part of the construction.
Test Result
The damper assembly operated satisfactorily
and retained its integrity for the 240 minute
heating period, during which time there were not
any significant gaps in or around the assembly
to permit the passage of flames.
Air Velocity Against
Pressure Drop
The graph opposite has been formulated to give
an indication of the pressure drop expected
through a fully open damper in relation to duct
air velocity.
Airflow Blade Leakage Against
Differential Pressure
The graph opposite illustrates the maximum
leakage obtainable when the damper is in a fully
closed position under ambient temperature
conditions.

each operational mode are detailed on
their respective data pages in this
brochure. In addition to their initial test
however, being a fire safety product, it
is also recommended that the units are
test operated regularly thereafter . Test
frequency will depend upon the
damper environment but, in the
absence of any other information, a
maximum interval of 6 months is
recommended. In addition an annual
visual inspection is also advisable to
permit cleaning and removal of any
airborne contaminants which may
affect the dampers operation.
Note
For safety the damper blades should
be closed on Modes 5,9, and open on
modes 6,10, before personally
approaching them for
inspection/cleaning.
Since the drive, linkage, motors and
electronic components on the ductgard
units are ‘sealed for life’ there should
be no requirement for periodic
maintenance and spares are not
normally required. Items such as reset
levers and test keys however can be
misplaced over time. In this event
replacements are readily available from
Head Office.

Outer Casing
Components for the outer casing are
manufactured from 1.2mm galvanised
steel. BS EN 10142:1991:FEP02G
formed into sections of average
dimensions 120 x 50mm with spigot
ends for connection to system
ductwork. Outer casing sections are
fully welded.
Inner Cassette
Components to form the inner cassette
on all four sides are from 1.5mm
galvanised mild steel. Components are
formed into a channel section of size
120mm x 50mm. The inner casing is
mechanically joined at the corners The
vertical components contain holes for
blade spindles. The horizontal
components are complete with return
edge channels for retaining the top and
bottom seals.
Damper Blades
The damper blades are made from
0.45mm thick (.018”) BS 1449 stainless
steel. Blades are formed into a hollow
sectional profile. The blade ends are
formed into individual circular drive
shafts and located on brass bushes
through the side channels.
Side seals of 0.25mm stainless (as per
blade specification) are formed and
pierced to accept blade drive shafts
and are assembled between frame and
blade ends. Top and bottom seals are
manufactured in the same material but
are retained on top and bottom frames
by returned channels fixed on in the
frame inner surface.
The blades are actuated by a 2mm
thick x 58mm steel channel located in
the side frame and acting on steel
pinions attached to blade ends. The
rack and pinions are galvansied and
are contained in the side frame.
Half gears as rack specification transfer
the sideways rack movement to circular
blade drive shafts. A drive bar moves
the rack up or down and is either hand
or motor controlled via a electro thermal
fuse.
