Mode 5DescriptionMode 5 is a fully automatic type of smoke andfire damper and operates on the basis of failsafe closure with automatic reset. It has beendesigned to close in smoke and fire conditionsupon signal from a fire detection system or inthe event of an electro thermal fusible linkseparating at a pre-determined temperature(72°C standard).OperationMode 5 is fitted with a square drive spring returnmotor which will hold the damper open for aslong as the supply voltage is available.Interruption of this supply will cause controlleddamper closure by way of the motors springreturn operation. In addition however, thedamper is also fitted with an electro thermalfusible link which will separate at a predeterminedtemperature (72°C standard) andclose the damper irrespective of motor position.All Mode 5 units are also fitted with a controlbox which is situated on the dampers ductworkextension and houses the integral PCB, statusindication L.E.D. and test facility. The test keyfacility allows local checks to be made on thedamper operation.The L.E.D., provides the following diagnosticchecks:-GREEN DISPLAY:- Power supply ON, unit set.RED DISPLAY:- Power supply ON, but unit infail safe mode.NO DISPLAY:- Power supply failure, unit in failsafe mode.The control box also provides an interface forremote status indication, smoke detectors andRCP control (see page 11 and 12).Control OptionsA - 24v DC Power SupplyB - 240v AC Power SupplyRe-Set ProcedureProvided the fusible link is intact and the remoteor local test facility is not being utilised thedamper will automatically reset after aninterruption of the supply voltage. The motor willtake approximately 80 seconds to fully open thedamper.The LED indicator and test facility are housed ina control panel mounted on the ductworkconnection sleeve. Fully assembled prior todespatch they require only the external electricalwiring connections to be made on site.OPTIONAL FEATURES■ A RANGE OF MULTIPLEX OR ELECTRO-MECHANICAL CONTROLPANELS■ REMOTE, ELECTRICAL BLADE STATUS INDICATION PANELS■ HEVAC INSTALLATION FRAME/DRY WALL FIXING FRAME■ ACCESS PANELMode 6Mode 6 performs in exactly the same manner asthe Mode 5 except that the operation is reversedand the unit is fail safe open.

Mode 9DescriptionMode 9 is a fully automatic type of smoke andfire damper and operates on the basis of failsafe closure with automatic reset. It has beendesigned to close in smoke and fire conditionsupon a failure of the supply voltage to the motoror in the event of an electro thermal fusible linkseparating at a pre-determined temperature(72°C standard). Volt free microswitches areincluded as standard.OperationMode 9 is fitted with a spring return square drivemotor which will hold the damper open for aslong, as the supply voltage is available.Interruption of this supply will cause controlleddamper closure by way of the motors springreturn operation. In addition however, thedamper is fitted with an electro thermal fusiblelink which will fail at a pre-determinedtemperature (72°C standard) and close thedamper irrespective of the status of the motor.An integral test pushbutton on the electrothermal fuse housing allows for the local testingof the damper operation.Motor Control OptionsA: 24V AC or DC supply.B: 240V AC supply.Note: All options are complete with positionmicroswitches as standard.Re-set ProcedureProvided the fusible link is intact the damper willautomatically reset after an interruption of thesupply voltage to the motor. The motor will takeapproximately 80 seconds to open the damper.The spring return motor and terminal box (iffitted) are mounted on the ductwork connectionsleeve. Fully assembled prior to despatch theyrequire only the external electrical connectionsto be made.Mode 10Mode 10 performs in exactly the same manneras the Mode 9 except that the operation isreversed and the unit is fail safe open. Themotor sets the unit in the full closed position andthe unit will only open in the event of a aninterruption of the supply voltage to the motor orseparation of the thermal fusible link.Ordering procedure: Back coverOPTIONAL FEATURES■ A RANGE OF ELECTRO-MECHANICAL CONTROL PANELS■ VOLT FREE CONTACTS FOR REMOTE INTERFACE■ REMOTE, ELECTRICAL BLADE STATUS INDICATION PANELS■ DAMPER MOUNTING TERMINAL BOX FOR MICROSWITCHAND/OR MOTOR CABLING■ HEVAC INSTALLATION FRAME/DRY WALL FIXING FRAME■ ACCESS PANELS5

Test DataFire TestsAll fire tests were conducted by the WarringtonResearch Centre to BS476 Part 20 1987.This standard describes the performance ofstructural elements under fire conditions. It wasdecided to mount the unit in the face of a 3m sq.vertical furnace, and subject it to the testdescribed.Test DescriptionThe test specimen was fixed to a brick wall builtwithin a framed lined with refractory concrete atthe test laboratory. This frame was thenmounted such that the complete assemblyformed the front vertical face of the gas firedfurnace. The furnace was provided withthermocouples arranged such that they wereevenly distributed over the exposed face of thetest construction and with their hot junction100m from the nearest part of the construction.Test ResultThe damper assembly operated satisfactorilyand retained its integrity for the 240 minuteheating period, during which time there were notany significant gaps in or around the assemblyto permit the passage of flames.Air Velocity AgainstPressure DropThe graph opposite has been formulated to givean indication of the pressure drop expectedthrough a fully open damper in relation to ductair velocity.Differential Pressure (Pa)Temperature - Deg C10009876543210098765432109876543Standard Time - Temperature Curve Of BS476 Part 20 198712001100100090080070060050040030020010000 20 40 60 80 100120 140160 180200 220 240Time - minutesSpecified Furnace Temperature2Airflow Blade Leakage AgainstDifferential PressureThe graph opposite illustrates the maximumleakage obtainable when the damper is in a fullyclosed position under ambient temperatureconditions.DuctgardLeakage underFire Test(Unit Tested 1m 2Face Area)Differential Pressure (Pa)1100009876543210009876543210098765432 3 4 5 6 7 8 9 10 2 3 4 5 6 7 8 9100Air Velocity M/S21312 3 4 5 6 7 8 9 10 2 3 4 5 6 7 8 9100Leakage Rate L/S

Operation &MaintenanceInstructionsOperating and MaintenanceInstructionsAll Ductgard units are tested beforeleaving the factory but should be testoperated prior to commissioning toensure correct operation. Quick andeasy testing and reset procedures foreach operational mode are detailed ontheir respective data pages in thisbrochure. In addition to their initial testhowever, being a fire safety product, itis also recommended that the units aretest operated regularly thereafter . Testfrequency will depend upon thedamper environment but, in theabsence of any other information, amaximum interval of 6 months isrecommended. In addition an annualvisual inspection is also advisable topermit cleaning and removal of anyairborne contaminants which mayaffect the dampers operation.NoteFor safety the damper blades shouldbe closed on Modes 5,9, and open onmodes 6,10, before personallyapproaching them forinspection/cleaning.Since the drive, linkage, motors andelectronic components on the ductgardunits are ‘sealed for life’ there shouldbe no requirement for periodicmaintenance and spares are notnormally required. Items such as resetlevers and test keys however can bemisplaced over time. In this eventreplacements are readily available fromHead Office.Trouble-ShootingAll Ductgard units are both inspected and tested before leaving our premises. Manufactured using maintenance free ‘sealedfor life’ components there is no reason why they should not reach site in full working order and continue to function wheninstalled providing that our fitting and wiring instructions have been adhered to. In the event of operational difficulties pleasecontact our Head Office for on-line guidance and advice.Telephone: (01253) 766911Ductgard units carry a full 1 year warranty from the date of delivery for all parts and labour.GilbertsDamper,Smoke andFire ControlRangeSmokegardDoor, Wall and PartitionMounted Smoke and FireDampersSeries 52Smoke Evacuation DamperSeries 50/51Fire Smoke DampersFiregardCurtain Fire DampersAirgardVolume ControlDampersSeries RDIris Duct Damper14
