Maintenance

– The functional reliability of the fire damper mustbe tested at least every six months; this has tobe arranged by the owner of the ventilationsystem; functional tests must be carried out incompliance with the basic maintenanceprinciples stated in EN 13306 and DIN 31051.

If two consecutive tests, one 6 months after theother, are successful, the next test can beconducted one year later.

– A functional test involves closing the damperblade and opening it again; with a spring returnactuator this can be done via remote control

– Fire dampers must be included in the regularcleaning schedule of the ventilation system.

– For details on maintenance and inspection,refer to the installation and operating manual

Functional descriptionThe spring return actuator enables the motorisedopening and closing of the damper blade; it canbe activated by the central BMS.In the event of a fire, the damper is triggeredthermoelectrically at 72 °C or 95 °C (use in warm

air ventilation systems). As long as power issupplied to the actuator, the damper bladeremains open. If the supply voltage fails, thedamper closes (power off to close). Motorised firedampers can be used to shut off ducts. The torqueof each actuator is sufficient to open and close thedamper blade even while the fan is running.The spring return actuator is fitted with limitswitches that can be used for capturing thedamper blade position.††

1Functional descriptionAir transfer units prevent fire and smoke fromspreading in buildings. The thermal releasemechanism closes the air transfer unit when therelease temperature (72 °C) is reached. Smokecan, however, spread below this temperature. Air

transfer units are installed (mortar-basedinstallation) in places where the general buildinginspectorate sees no risk, for example:

– As an inlet for additional supply air in the wallsof required corridors (escape routes) if the inletis near the ground (centre line up to 500 mmabove floor surface)

– In installation shafts as long as they havesufficient fire resistance where they penetratecompartment floors

– In installation ducts as long as they havesufficient fire resistance where they penetratecompartment floors or walls (except for

necessary corridors or escape routes)

The air transfer unit is an FKS-EU fire damper with72 °C thermal release mechanism (constructionwith fusible link) and cover grilles both ends.††

Functional descriptionAir transfer dampers are designed to shut offopenings for air transfer in fire resistant internalwalls and ceiling slabs. To prevent smoke fromspreading in buildings, it is extremely importantthat the smoke is detected at an early stage. Duct

smoke detector Type RM-O-3-D is required tocontrol and trigger the air transfer damper. Thesmoke detector operates on the principle of lightscattering and detects the smoke regardless of itstemperature so that the fire dampers can beclosed before the release temperature is reached.The thermoelectric release mechanism of thespring return actuator also triggers the closure ofthe damper blade. When the release temperature(72 °C) is reached, the temperature sensor in theairflow interrupts the supply voltage to the springreturn actuator. The spring return in the actuatorcauses the fire damper to close (power off toclose). A second temperature sensor monitors the

ambient temperature. If the supply voltage fails,the damper closes. Air transfer dampers consist ofan FKS-EU fire damper, an RM-O-3-D duct smokedetector with general building inspectorate

licence Z-78.6-125, a spring return actuator(24 V AC/DC or 230 V AC) with two integral limitswitches, and cover grilles on both ends.

Special characteristics– Easy electrical connection

– Integration into the central BMS withTROXNETCOM– General building inspectorate licence: Z-6.50-

2231For further and up-to-date information, includingthe general building inspectorate licence and theoperating and installation manual, please refer toour website. For a more detailed selection anddesign of our fire dampers please refer to theEasy Product Finder design programme on ourwebsite.

FKS-EU

1Design information– Approved only for use in ventilation and air

conditioning sytems– If the fire damper is installed in a solid wall,

solid ceiling slab, lightweight partition wall orshaft wall with a lower fire resistance class than

that of the fire damper, the fire resistance classof the wall or ceiling slab applies also to theFKS-EU (details upon request)

– Ducting must be installed in such a mannerthat it does not impose any significant loads onthe fire damper in the event of a fire.

– For particular applications it is recommendedthat flexible connectors are used to connectrigid ducting to the unit.

– For further information relevant to design, inparticular information on installation situations,please refer to the operating and installationmanual.

Incorrect useNever use the fire damper:

– in areas with potentially explosive atmospheres– as a smoke control damper– outdoors without sufficient protection against

the effects of weather– in atmospheres where chemical reactions,

whether planned or unplanned, may causedamage to the fire damper or lead to corrosion

If this fire damper is used in Germany:– Do not use it in extract air systems in

commercial kitchens.

– Two integral limit switches with volt-freecontacts enable the damper blade positionindication (OPEN and CLOSED)

– If the unit is not connected to ducting, covergrilles are required on both ends.

– In combination with a spring return actuator, aduct smoke detector RM-O-3-D and covergrilles on both ends this is an air transferdamper with general building inspectorate

licence: Z-6.50-2231

To prevent smoke from spreading in buildings, it isextremely important that the smoke is detected atan early stage. A duct smoke detector RM-O-3-Dcan be used to activate FKS-EU fire dampers witha spring return actuator. The duct smoke detectoroperates on the principle of light scattering anddetects the smoke regardless of its temperatureso that the fire dampers can be closed before therelease temperature is reached.

Duct smoke detector Type RM-O-3-DThe duct smoke detector RM-O-3-D is fitted in thelower inspection access opening of the FKS-EUand hence, just as the spring return actuator, anintegral part of the fire damper.

Essential characteristics of the duct smokedetector:

– General building inspectorate licence Z-78.6-125

– For airflow velocities from 1 – 20 m/s– Independent of the airflow direction– Supply voltage 230 V AC, 50/60 Hz*– Volt-free signal and alarm relays– Integral signal lamps– Contamination level indicator– Automatic adjustment of alarm threshold– Long service life– Temperature range 0 – 60 °C

* The 24 V DC construction includes a voltagemonitoring module

Duct smoke detector RM-O-3-D

Duct smoke detector RM-O-VS-D

General– To prevent smoke from spreading in buildings,

it is extremely important that the smoke isdetected at an early stage.

– Duct smoke detectors that operate on theprinciple of light scattering detect the smoke

regardless of its temperature so that the firedampers can be closed before the releasetemperature of 72 °C is reached

– If the air contains suspended particles, as isthe case with smoke, beams of light aredeflected off these. A sensor (photodiode),which does not receive light in clear air, isilluminated by the scattered light.

– The fire damper or smoke protection damperblade is released when the brightness of thescattered light exceeds a certain threshold

NoteFor details please refer to the technical leaflets for

RM-O-3-D and RM-O-VS-D.
