DUCTGARD - Gilberts (Blackpool)

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
