4.4 Cone of Vision
The FSL100 flame detector has a cone of vision of 90° so it can monitor an area extending from floor to ceiling and
extending to approximately 23 m (FSL100-UV and UVIR) or 35 m (FLS100-IR3).

If monitoring a solid object, the mounting height (h
d
) of the flame detector should be at least twice the height (h
o
) of the highest
object in the monitored zone:
Detector height (h
d
) = 2 x height of the highest object (h
