Long-range version with IRS 272 (optional)
At installation heights above 3 m, the detector should point
downward at an angle of 2°.
Side view/top view
The detector requires a stable reference for the entire
detection zone. The detection zone consists of two
subzones (separated by the central level). The subzones
cannot be referenced to different surfaces that may consist
of differing materials. The middle level of a detection zone
is in the detector's longitudinal axis, which is perpendicular
to the installation surface (housing floor).
