Maintenance
– The functional reliability of the fire damper
must be tested at least every six months;
this has to be arranged by the owner
of the ventilation system; functional tests
must be carried out in compliance with
the basic maintenance principles stated
in EN 13306 and DIN 31051. If two consecutive
tests, one 6 months after the other,
are successful, the next test can be
conducted one year later.
– A functional test involves closing the damper
blade and opening it again; with a spring return
actuator this can be done via remote control
– Fire dampers must be included in the regular
cleaning schedule of the ventilation system.
– For details on maintenance and inspection,
refer to the installation and operating manual

Functional description
In the event of a fire, fire dampers shut
automatically to prevent the propagation
Construction with fusible link
of fire and smoke through ductwork to adjacent
designated fire compartments. In the event of a
fire, the damper is triggered at 72 °C or at 95 °C
(use in warm air ventilation systems) by a fusible
link. The release mechanism is accessible
and can be tested from the outside.

Function
Construction with
spring return actuator
FKRS-EU
Functional description
The spring return actuator enables the motorised
opening and closing of the damper blade;
it can be activated by the central BMS.
In the event of a fire, the damper is triggered
thermoelectrically at 72 °C or 95 °C
(use in warm air ventilation systems).
As long as power is supplied to the actuator,
the damper blade remains open.
If the supply voltage fails, the damper closes
(power off to close). Motorised fire dampers
can be used to shut off ducts. The torque
of each actuator is sufficient to open and close
the damper blade even while the fan is running.
The spring return actuator is fitted with limit
switches that can be used for capturing
the damper blade position.

Function
Use as an
air transfer damper
FKRS-EU
Functional description
Air transfer dampers prevent fire and smoke
from spreading in buildings. The thermal release
mechanism closes the damper blade when
the release temperature (72 °C) is reached.
Smoke can, however, spread below
this temperature. Air transfer dampers
are installed (mortar-based installation)
in places where the general building
inspectorate sees no risk, for example:
Special characteristics
– General building inspectorate licence
Z-19.18-2128
– Air transfer damper
without duct smoke detector
1
– As an inlet for additional supply air in the walls
of required corridors (escape routes)
if the dampers are installed near the ground
(up to 500 mm above OKFF)
– In installation shafts as long as they have
sufficient fire resistance where they penetrate
compartment floors
– In installation ducts as long as they have
sufficient fire resistance where they penetrate
compartment floors or walls
(except for necessary corridors
or escape routes)
The air transfer damper is an FKRS-EU
fire damper with 72 °C thermal release
mechanism (construction with fusible link)
and cover grilles both ends.

Correct use
FKRS-EU
Design information
– Approved only for use in ventilation
and air conditioning sytems
– A class of performance up to EI 120
(ve, ho, i ↔ o) S can only be achieved
with ducts connected on both ends,
or with a duct on one end and a cover grille
on the other end.
– If the fire damper is installed in a solid wall,
solid ceiling slab, lightweight partition wall
or shaft wall with a lower fire resistance class
than that of the fire damper, the fire resistance
class of the wall or ceiling slab applies also
to the FKRS-EU (details upon request)
– Ducting must be installed in such a manner
that it does not impose any significant loads
on the fire damper in the event of a fire.
1
– For particular applications it is recommended
that flexible connectors are used to connect
rigid ducting to the unit.
– Fire dampers must be installed,
connected and secured according
to the operating and installation manual.
Incorrect use
Never use the fire damper:
– without specially approved attachments
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 cause
damage to the fire damper or lead to corrosion

Application
– Ducting must be installed in such a manner
that it does not impose any significant loads
on the fire damper in the event of a fire.
– For information on how to limit such loads
please refer to the guideline regarding fire
protection requirements on ventilation systems
(Lüftungsanlagen-Richtlinie, LüAR)
– As ducts may expand and walls may become
deformed in the event of a fire, we recommend
for the following applications using flexible
connectors when connecting the fire damper
to rigid ducts: installation into lightweight
partition walls, into lightweight shaft walls,
and installation with a fire batt
– Flexible connectors should be installed
in such a way that both ends can compensate
both tension and compression
– Flexible ducts can be used as an alternative
– To ensure that the open damper blade
is contained within the damper casing
on the installation side, an extension piece
is required for nominal size 224 and above
– Flexible connectors are supplied separately
and can be fixed with clamps,
for example (by others)
– Flexible connectors
are also available separately
Materials and surfaces
– Flexible connectors
made of fibre-reinforced plastic
– Fire resistance properties to 4102; B2
Note
For more information please refer
to the installation and operating manual.

control of the fire damper and/or release
by a suitable duct smoke detector
– If the supply voltage fails, or with thermoelectric
release, the damper closes (power off to close)
– Fire dampers with spring return actuators
can be functionally checked
OPEN/CLOSED/OPEN
– Ambient temperature of the actuator,
normal operation –30 to 50 °C
– Two integral limit switches with volt-free
contacts enable the damper blade position
indication (OPEN and CLOSED)
– BLF24-T-ST TR: The connecting cables
of the spring return actuator are fitted
with plugs, which ensure quick and easy
connection to the TROX AS-i bus system

Duct smoke detectors

Description
Duct smoke detector
RM-O-3-D
FKRS-EU
General
– To prevent smoke from spreading in buildings,
it is extremely important that the smoke
is detected at an early stage.
– Duct smoke detectors that operate
on the principle of light scattering detect
the smoke regardless of its temperature
so that the fire dampers can be closed before
the release temperature of 72 °C is reached
– If the air contains suspended particles,
as is the case with smoke, beams of light
are deflected off these. A sensor (photodiode),
which does not receive light in clear air,
is illuminated by the scattered light.
– The fire damper or smoke protection damper
blade is released when the brightness of the
scattered light exceeds a certain threshold
Application
RM-O-3-D:
– Duct smoke detector for fire dampers
and smoke protection dampers
– 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 or 24 V DC

This catalogue provides convenient
quick sizing tables for fire dampers.
The volume flow rates for all available
dimensions and nominal sizes are provided
based on a particular differential pressure.
Sizing data for other volume flow rates
and differential pressures can be determined
quickly and precisely using
the Easy Product Finder design programme.
Easy Product Finder
The Easy Product Finder
allows you to size
products using your
project-specific data.
You will find
