2 INTRODUCTION 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-EN fire test standard and includes mandatory CE marking.

3 Control Mode Options The Gilbert s 2014 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. Mode Description Page 9A Fully automatic opening operating on 24v with failsafe spring 4 return closure via 72 c electro thermal link release 9B Fully automatic opening operating on 230v with failsafe spring 4 return closure via 72 c electro thermal link release 10A Fully automatic closure operating on 24v with failsafe spring 4 return opening via 72 c electro thermal link release 10B Fully automatic closure operating on 230v with failsafe spring 4 return opening via 72 c electro thermal link release

4 DUCTGARD Duct Mounting Smoke and Fire Control Dampers Mode 9 Mode 10 Description Mode 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. 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. Description Mode 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. Motor Voltage Control Options Mode A: 24V AC or DC supply. Mode B: 230V AC supply. Note: All options include 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. 4

11 Control Systems Gilberts offer a wide choice of hard wired and multiplex controlled systems to meet the challenge of effective fire and smoke control monitoring. Available as stand alone, or suitable for interfacing or incorporating with building management or fire/smoke control systems designs, the range includes four simple off the shelf packages through to bespoke designs to satisfy the most demanding criteria. Gardex (Modes 9/10 Options Only) Multiplex System The Gardex system has been designed to reduce the cost of electrical wiring installations and satisfy the most complex of control changes. Up to 126 dampers can share the same 2 wire communication line to transmit information to and from the central controller.

14 DUCTGARD Duct Mounting Smoke and Fire Control Dampers Operation & Maintenance Instructions 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. Trouble- Shooting 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) Ductgard units carry a full 1 year warranty from the date of delivery for all parts and labour.
