SST F120 - Orientation of the Flame Detector; Dust, Debris, Salt, and Snow; Enclosures Protected by Glass, and Plexiglas

120-16 January, 2016
Model F120 UV/IR Flame Detector
Ceiling
Wall
Orientation of the Flame Detector
The F120 will operate in any orientation. Recommended orientation is above the intended
protective zone to insure a clear eld of view and minimal accumulation of dust and debris on
the lens surface. The detector can be mounted at a minimum declination of 20 degrees or at
the recommended declination of 45 degrees. If the ame detector is installed at a corner of
a room at a 45 degree angle, the coverage path of the detector will extend from the detector
across the ceiling and from the detector straight down the wall and towards the oor. The
F120 detector housing is marked “TOP” to identify the recommended side of the detector
that should be mounted facing up. This orientation prevents the accumulation of dust and/
or debris on the lens and the self-test oriface.
Dust, Debris, Salt, and Snow
If the detector is installed above the intended protective zone, angle the detector a minimum
of 20 degrees down or at the recommended declination of 45 degrees to prevent any
accumulation of dust, debris, salt or snow on the lens.
The internal electronics of the detector generates enough heat that no icing should occur.
Utilize a shade or cover if necessary to protect the lens from heavy snow.
Enclosures Protected by Glass, and Plexiglas
The ame detector must have an unobstructed view of the area it is intended to monitor.
If an area is enclosed with a glass or Plexiglas, UV and IR radiation will not travel through
these materials and will not be detected by the detector. Please consult with Safety Systems
Technology for recommendations regarding your specic application.
