aligning the 4 projections on
the cover to the 4 cut outs
on the lens.
(The lens has vertical
orientation. Be sure the lens is
correctly orientated when
mounting.)
2.Separate the lens from
the cover. Apply the
provided area masking
plate to the inside of the lens
on the zone to be eliminated.
4.Mount the lens holder. make
sure the lens holder is held

Length of Lower Detecion Area decides detection length
The upper detection area stays parallel to the ground at all time. The lower detection area moves as shown above depending on the switch
position. Detection length is therefore limited by the length of lower detection area, since both upper and lower detection area have to be
blocked at the same time to activate the sensor.

Detection
·This product detects temperature differences between the moving object and the background temperature in the detection
area. If the object does not move, the detector can not detect it.
·This product has directional characteristic it is difficult to detect the target that is approaching the detector.
·If there is a traffic near the dettection area, please adjust detectiion 1.5m to 2.0m (5ft to 7ft) away from movements.
IMPORTANT!
As shown above 5-2, there are always 7 active detection fingers. If the area masking plate is not applied, the active fingers
are varied by area adjustment as explained at left.
Please check which fingers are active before applying area masking plate.
IMPORTANT!
