2.4 Limitations on use
● The Dräger Flame 3000 is not approved for use in oxygen-enriched
atmospheres.
● As the Dräger Flame 3000 responds to visible flames, it cannot be used in
locations where flare stacks and other open flames are within its field of view
without triggering false alarms.
● The Dräger Flame 3000 is unable to detect fires that are invisible to the
naked eye, such as those using pure hydrogen, methanol and sulphur as
fuel.
● The sensitivity of the Dräger Flame 3000 to flame is reduced by obscurants
such as smoke, fog and other airborne particulates. The Dräger Flame 3000
may be blinded by extremely dense obscurants.
● Although the Dräger Flame 3000 is insensitive to arc welding, arc welding
should not take place within 1 m of the flame detector.

3.1 Prerequisites for installation
Observe the following:
● Ensure that the Dräger Flame 3000 has an unobstructed view of the areas
to be protected.
● Ensure that the mounting position is free from vibration or movement.
● Ensure that the mounting position has sufficient support for the Dräger
Flame 3000 and allows for horizontal adjustment.
● Ensure that the Dräger Flame 3000 is protected from sources of impact
damage and from being knocked out of alignment.
● Ensure that the area under observation has sufficient detector coverage for
all possible hazards (multiple detectors may be required) taking into account
any obstructions and congestion.
● Install the Dräger Flame 3000 as far away as possible from local sources of
possible electrical interference, such as X-rays, RF (radio frequency)
interference or electrostatic discharge.
● Minimize the exposure of the enclosure front cover window to contaminants
such as oil, water (deluge water, rain and sea spray), snow, and ice. Where
the Dräger Flame 3000 is to be mounted at a low level avoid contamination
from equipment situated above the mounting position.
● If dense smoke is expected to accumulate at the onset of the fire, the Dräger
Flame 3000 should be mounted 1 – 2 m below the ceiling level where
possible.
