3.1
Prerequisites for installation
When selecting a mounting position for the Dräger Flame 3000
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.
•
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.
•
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.
•
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.
•
Ensure there is maintenance access to the Dräger Flame 3000
(e.g. direct, ladder or scaffold access).
•
Ensure that mounting supports are compatible with the Dräger
Flame 3000 mounting brackets.
•
Ensure that the Dräger Flame 3000 does not have a direct view
of any sources of flame used during normal operations, such as
flare stacks.
•
Ensure that the Dräger Flame 3000 is positioned so that it is not
directly facing the sun.
All of these issues are crucial to a successful installation. They
should be observed during the detailed design, construction and
commissioning phases of the installation of a fire detection system.
3.1.1
Detector coverage
Software analysis of the actual detector field of view may be required
to ensure adequate coverage of the hazards. This analysis can also be
used to optimize the number of detectors and the loop configuration.
3.1.2
Power and cable requirements
The Dräger Flame 3000 requires a supply voltage of 18 – 30 V at the
input terminals.
The installation location and local regulations and standards determine
the cable specification.
The Dräger Flame 3000 contains further details of the power and
cable selection requirements. Contact Dräger for details.
