PROTECTION DISTANCE
Outdoor 3.3' to 36' (1 to 11m)
Indoor
＊Protection distance (between sensor/re ector)
should be placed in the rated range.
＊Sensitivity allowance will be greatly decreased when the protection distance deviates from the rated range.
(See the sensitivity allowance-protection distance curve for PB-11BE)
BEAM ALIGNMENT
・Fine tuning using a volt meter is required. (See section 5)
HEIGHT OF INSTALLATION
Install the sensor at a height of 31" to 39" (80 to
100cm) to catch a human target.
(Install vertically so that the center of the sensor
lens and middle part of the re ector assembly are
placed at the same height.)
POSITION OF INSTALLATION
Using the adjustments, the lens can move
horizontally (±90 degrees) and vertically (±10
degrees) allowing the unit to work in all
directions.

CAUTIONS ON INSTALLATION
・Avoid over head wiring.
・When installing indoors, wiring procedures
similar to those for telephone or intercoms
are acceptable. Outdoor wires should be
placed inside conouit, or underground
cable/metal shielded cable should be used.

・Hazardous weather such
as heavy rain or frost may
cause false alarms.
Sensitivity allowance of
re ective type beam
sensors is comparatively
lower than that of
standard type beams.
