For best performance, the detector should be mounted on a rigid
surface in a low vibration area.
Dense fog, rain or ice can absorb IR radiation and reduce the
sensitivity of the detector.
Although IR detectors are less affected by smoke than other
detectors, the X33AF PL should not be placed where rising
combustion products can obscure its vision. If smoke is expected
before fire, smoke or other alternative detectors should be used in
conjunction with the X33AF PL. For indoor applications, if dense
smoke is expected to accumulate at the onset of a fire, mount the
detector on a sidewall at least a few feet (approximately 1 meter)
down from the ceiling.
If possible, fire tests should be conducted to verify correct detector
positioning and coverage.
5.1.1 Detector Orientation
Refer to Figure 2 and ensure that the oi plate will be oriented as
shown when the X33AF PL is mounted and sighted. This will ensure
proper operation of the oi system and will also minimize the
accumulation of moisture and contaminants between the oi plate and
the viewing windows. The oi plate includes an arrow, which should be
pointed in the up direction, indicating that the oi plate and detector are
correctly oriented.
IMPORTANT: The oi plate must be securely tightened to ensure
proper operation of the oi system (40 oz./inches recommended).
