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.

Operation & MaintenanceInstructions

Trouble-Shooting

Gilberts Damper, Smoke and Fire Control Range

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.
