2.4 Limitations on use
– The flame detector is not approved for use in oxygen-enriched
atmospheres.
– As the flame detector responds to flame, it cannot be used in locations
where flare stacks and other open flames are within its field of view without
triggering false alarms.
– The flame detector may be obscured by extremely dense fog, smoke or
other airborne particulates.
– Arc welding should not take place within 10 m of the flame detector when
using the highest sensitivity setting.

3 Mounting
3.1 Prerequisites for installation
When selecting a mounting position for the flame detector, observe the
following:
– Ensure that the flame detector 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 flame
detector and allows for horizontal adjustment.
– Ensure that the flame detector is aimed downwards by at least 10° to 20°.
This will reduce the build-up of contaminants on the lens.
– Ensure that the flame detector is protected from sources of impact damage
and from being knocked out of alignment.
– Install the flame detector as far away as possible from local sources of
possible electrical interference, such as X-rays, RF (radio frequency)
interference or electrostatic discharge.
