The detector’s overall range is determined by
the lower beam range.
• The
upper beam
must always be parallel
to the ground
• The
lower beam
must be adjusted in
relation to the position of the lower lens (2
m or 5 m mark).
• Given that the 2 beams must be
simultaneously broken to trigger an alarm,
the detector range is limited to the lower
beam range as shown in the diagram
below.

IMPORTANT
• The 2 m or 5 m indications on the product
should only be used to help position the
lower lens.
• To determine the detection range, please
refer to the tables above.

• The lower lens is factory-positioned for
detection at 5 m. If 2 m detection is
required:
• The detection range is determined by the
lower lens setting and the detector
installation height.
* Detection range data may vary in relation to atmospheric
conditions.
