OPTICAL AXIS ALIGNMENT

There are two ways for optical axis alignment, by using a level meter or a tester.

1. Alignment using a level meter

(1) Rough adjustment

While looking into the scope located in the center of the

lens 10 to 15cm away from it, turn the turntable and hori-

zontal adjustment screw for adjustment in the horizontal

direction and the vertical adjustment screw for adjust-

ment in the vertical direction until the detector on the other

side is in the center of the scope as shown in the scope

view shown below.

2. Alignment using a tester

(1) Rough adjustment

While looking into the scope located in the center of the

lens 10 to 15cm away from it, turn the turntable and hori-

zontal adjustment screw for adjustment in the horizontal

direction and the vertical adjustment screw for adjust-

ment in the vertical direction until the other detector is in

the center of the scope as shown in the scope view shown

below.

(2) Fine adjustment

Check the level meter of the receiver.

When the square marked level lamp in the table on the

label is turned off, it means alignment is completed.

If the lamp remains on, adjust the horizontal and vertical

adjustment screws of the transmitter and receiver until

the square marked level lamp turns off.

(2) Fine adjustment

Insert the tester stick into the tester hole in the receiver

to check the tester voltage.

If the measured value is 3V

or more, adjustment is

completed.

If it is less than 3V, adjust

the horizontal and vertical

adjustment screws of the

transmitter and receiver

until 3V or more voltage is

obtained.

SENSITIVITY ADJUSTMENT

It is possible to adjust the detection sensitivity by adjusting the interruption time adjustment volume.

When the unit is mounted on a wall, the interruption time can be set longer because the intruder cannot move quickly. This way,

it is possible to prevent an erroneous operation by a bird, small animal, paper and other object that flies in.

Adjust the sensitivity with the moving speed of a possible intruder taken into consideration. Also, be sure to check the unit for

operation after adjustment.
