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
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.

Fire dampers
General information FKS-EU
1 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.

Design information
– Approved only for use in ventilation

– 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 FKS-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.
– 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.

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
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
