DUCTGARDDuct Mounting Fire and Smoke Dampers
Introduction
Control Mode Options
Gilberts Ductgard presents an ‘engineered’ range of
combined smoke and fire dampers suitable for use in all types of HVAC ductwork. Benefitting from over 50 years of engineering experience in the industry considerable
ingenuity has been applied in the design and construction
of this product to produce a damper of high efficiency, reliability, durability and ease of use.
Ductgard has been tested to the latest BS-EN1366-2 fire test standard and includes mandatory CE marking.
The Gilbert’s Ductgard presents a re-engineered range of
combined fire and smoke dampers suitable for use in HVAC ductwork systems.
Developed from a well proven heritage of tried and tested damper designs, considerable ingenuity and manufacturing expertise has been applied to produce a robust, effective, competitive unit that is easy to install and maintain.
The unit is designed to fit within all types of ductwork at its junction with a fire barrier wall, where it can be fixed directly in or immediately adjacent to the building structure in both
the horizontal and vertical positions.
With a choice of 4 different modes of operation all units
are fully automatic and motorised. All units comprise of an
air-tight galvanised casing (DW144 Class C Specification) with stainless steel interlocking blades and frame side seals, which provides a four-hour fire rated assembly. Sizes range from 200 x 200 upto a maximum of 1000 x 1000 in one unit
Dampers over this size are supplied in multiple units but are not CE compliant.

Mode 9
Mode 10
DescriptionMode 9 provides a fully automatic type of smoke and fire damper that 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.
OperationMode 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 Voltage Control OptionsMode A: 24V AC or DC supply.
Mode B: 230V AC supply.
Note: All options include position microswitches as standard.
Re-set ProcedureProvided 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.
DescriptionMode 10 performs in exactly the same manner as the Mode
9 except that the operation is reversed and the units are fail safe open. The motor sets the unit in the full closed position
and the unit will only open in the event of an interruption of the supply voltage to the motor or separation of the thermal fusible link.

Ancillary Items
Gilberts range of ancillary Items have been designed for use in conjunction with both the Ductgard and Smokegard models. Purpose built for straightforward connection and compatibility they offer a number of useful services.
Remote Indicators/Master Monitors
Gilberts remote indicator panels can be
linked to damper Modes 5 and 6 and
will provide remote indication of the status of one or more dampers.
Ref:
• RT1 (1 damper)• MM1-12 (upto 12 dampers)
Larger Panels available upon request
Master Monitor
A more advanced form of remote indication is available with a master monitor. This unit provides remote indication for the status of up to 12
individual dampers.
Ref:
• MM1-12*
* dependant on number of dampers on
the system
Standard Power Supply
Standard power supplies are available in two sizes to suit up to 6 or up to 12
dampers. They provide conversion from 240v AC input to a smooth and stabilised 24v DC output.
Ref:-
• G6 = 6 UNIT OUTPUT• G12 = 12 UNIT OUTPUT• G6R = 6 UNIT OUTPUT + RELAY• G12R = 12 UNIT OUTPUT + RELAY
Uninterruptible Power Supply
Uninterruptible power supplies
operating on a 240v AC input provide a smooth 24v DC output to power up to 12 dampers. Unlike standard
power supplies however, in the event of a power failure, there will be an automatic changeover to in-built batteries without tripping the dampers
providing continued power for a period of up to 1 hour.

Operating and Maintenance Instructions
All Ductgard units are tested before leaving the factory but should be test operated prior to commissioning to
ensure correct operation. Quick and easy testing and reset
procedures for 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 9
and open on modes 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.
All Ductgard units are both inspected and tested before
leaving our premises. Manufactured using maintenance free ‘sealed for life’ components there is no reason why they
should not reach site in full working order and continue to
function when installed providing that our fitting and wiring instructions have been adhered to.
In the event of operational difficulties please contact our Head Office for on-line guidance and advice.
Telephone: (01253) 766911
Ductgard units carry a full 1 year warranty from the date of
delivery for all parts and labour.

Specification Fire and smoke dampers shall be LPCB certificated and pass the test requirements stated in EN 1366-2 with an ES classi-fication to EN 13501-3. Dampers to be fitted with an actuator that can respond to a smoke alarm signal to ensure closure
at the first sign of smoke.
Motors Dampers to be motor operated with a failsafe thermal fuse
set to operate at 72°C. The damper will close (or open) in
less than 30 seconds.
Damper Blades & Linkage Dampers to have opposed blade operation with interlocking double skinned blades on robust 19mm spindles for both re-
sistance to fire and daily airflow exposure. The drive linkage shall be fully enclosed and set outside of the air stream for
protection against damage and air contamination.
Casing Stainless steel gaskets shall be provided at the top, bottom and sides to reduce casing leakage to below the levels stated in EN 1366-2. Damper casings shall be fully welded to meet
the air tightness test requirements of HVCA specification DW144 to classes A, B and C at up to 1500Pa.
Approvals The fire and smoke damper shall have a tested or assessed installation method that matches the requirement of the sup-porting construction into which it is built.
