Fail-safe is by means of a uniqueand patented Electrical ThermalRelease (ETR) which operates at72 °C, or if power supply isinterrupted. The ETR incorporatesa safety feature, that ensures thefail-safe status of the damper ifthe ETR is not fitted on to theductwork. Additionally a greenLED lamp is built into the ETRhousing. This gives the user asimple and clear visual checkthat the Actuator is receivingpower, the ETR is correctly fitted, and the thermalfuse is intact.
A manual test switch allowsperiodic operation of the damperfor testing purposes, simulatingactual fail-safe release under fireconditions.
The associated electrical controlmodes are available in 24 Volt,120 Volt or 230 Volt versions.
Range and Application
IntroductionActionair has, for many years, been associated in the design,development and manufacture of life safety equipment, includingthe supply of fire damper products to the offshore and marineindustry. The Actionair A-60 Fire Damper has been specificallyengineered to meet stringent legislation.
The A-60 Marine Fire Damper compliments the comprehensiverange of automatic fire and smoke dampers and associated
controls, provides the complete solution for shipboard airconditioning and ventilation systems fire safety engineeringstrategies.
The A-60 Marine Fire Damper has been designed for inclusion in airconditioning and ventilation systems and is tested and approvedfor fitting to class A-60 divisions (bulkheads and decks), whensuitably insulated (refer to insulation details).
The A-60 dampers can be used where the maximum systempressure is up to 1500 Pa and duct velocities to 15m/s.
A-60 Marine Fire Dampers are designed for applications in normal dryfiltered air systems and should be subjected to a planned inspectionprogramme, with cleaning and light oil lubrication in accordance withgood industry practice. When exposed to fresh air intakes and/orinclement conditions please refer to Actionair Technical Sales Office.
The A-60 Marine Fire Damper is suitable for both vertical andhorizontal applications, with airflow in either direction. The dampersare normally open, and fail-safe to the closed position.

A-60 Marine Fire Dampers
PTR ETR
SpecificationThe Actionair A-60 Marine FireDamper is constructed fromgalvanised steel 1.2mm thick,40mm flanged rectangular orcircular casing, (316 stainlesssteel option available). 75mm interlocking 430 gradestainless steel aerodynamicblades, steel blade end bearingsand 300 grade stainless steelperipheral gasketting. (316grade stainless steel blade andblade end bearing available).The totally enclosed precisemovement opposed blade driveis positioned out of the airstreamfor protection against damage,and is hard wearing and freerunning.
ElectricalThe Actionair direct-coupledspring return fail-safe electricalcontrol modes are fitted withhalogen free low smoke andfume electrical cable. They havea 60 second reset time and a 20second release time. Eachactuator has a 72°C ratedelectrical thermal release (ETR).The ETR incorporates a safetyelectrical interlock that onlypermits actuator operationwhen correctly fitted.A green ‘Healthy’ indicationlamp is built into the ETRhousing to give a simple andclear visual check that theactuator is receiving power, theETR is correctly fitted, and thethermal fuse is intact.A manual test switch allowingperiodic operation of thedamper for testing purposessimulates actual fail-safe releaseunder smoke/fire conditions.End switches are provided witheach mode for reset and releasemonitoring.
PneumaticThe Actionair direct coupledspring return fail-safe pneumaticcontrol mode requires an airpressure of between 5 to 8 bar(72 to116 psi) to operate. Theyhave 3 second reset and releasetime. Each actuator has apneumatic thermal release(PTR).The PTR assembly is suppliedwith 500mm nylon tubing thatconnects to the quick fitcouplings of the PTR andactuator. Incorporated is a fail-safe 74°C fusible link. When thisoperates, air exhausts from theactuator, permitting the springreturn actuator to go to the fail-safe position, thus closing thedamper. Switch box andsolenoid accessories areavailable for monitoring andcontrol.

The IP54 rated Control Modes, are locatedoutside of the ductwork for ease of accessand installation.Control Modes fitted to dampers up to400mm high, can be fitted in any one ofthree orientations i.e. vertically down,horizontally or vertically up. Positions 1, 2,or 3).Two sizes (Compact and Universal) ofControl Mode are utilised. This flexibility ensures that the smallerdamper sizes and Control Mode requirethe minimal amount of room. For dampersizes above 400mm high the control modeis fitted vertically.Correctly sized Control Modes aredesigned to fit only to the relevant sizeddamper.The control modes are direct coupled tothe damper utilising a unique user friendlypositive connection system. This allowsthe dampers and actuators to be suppliedseparately, offering shipping and storagebenefits.
Blade FeaturesThe damper blades are aerodynamicdouble skin, type 1.4016 (430 grade) FerriticStainless Steel, which are 75mm wide andwhen closed interlock to form a positive fireresisting shield. Incorporated in the bladeare steel blade end bearings.

The data presented is from the LaboratoryDetermination of Acoustic andAerodynamic Performance of A-60 MarineFire Dampers.
A programme of extensive tests wascarried out by an independent test facility,approved under the NAMAS Scheme, inaccordance with BRITISH STANDARDSNos. 4196, 4773, 4856, 4857 and 4954.
From the selection of a duct velocity withinthe operational parameters of the dampera resultant pressure drop from Table 1 canbe determined and the sum of these twocomponents applied to the Velocity xPressure Drop Vs Sound Power LevelGraph. (Table 2).
The graph is the result of a full range of acoustic tests with the blades setin the fully open position.
The Spectrum Correction Data is appliedto the number obtained from the graphand a complete Sound Spectrum of FlowGenerated Noise for both Outlet (in duct)and Breakout (casing radiated) is obtained.
