3.3.3 Environmental
Factors
•
Observe the ambient temperature range for the specific model – refer to Environmental
Specifications (Section 8.2.5). For outdoor installations or other areas exposed to
intense, direct solar radiation, the detector may reach temperatures well above
specifications. For this condition, a cover for shade may be required to bring the
detector temperature within specifications. As with any cover or object near-by, make
sure the field of view of the detector is not obstructed.
•
Avoid conditions of ice build up on the optical detector windows. Complete icing-over of
the IR detector window can result in fault conditions.
•
Modulated reflected sunlight shining at the face of the FL4000 reduces flame detection
distance.

CAUTION:
Do not unscrew the Electronic Module Tube without first removing the Optical
Module Assembly. Unscrewing the Tube from the Junction Module Base while
the Optical Module Assembly is attached will invariably damage the unit.
