SENSITIVITY ADJUSTMENT

It is possible to adjust the detection sensitivit y by adjusting the interruption

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,

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

operation after adjustment.

OPTICAL AXIS ALIGNMENT

There are two ways for optical axis alignment, by using a level LED and a tester.

1. Selectable Beams

Crosstalking will occur when using multiple beams

for stack beam or long distance application, which can

cause no-alarmproblems. This NRXXTM series has

selectable beams up to 4 channel which can be used

to avoid crosstalking.

TROUBLESHOOTING

Problem

Possible cause

An obstacle exists between transmitter and receiver.

False alarm is output

frequently.

Optical axis alignment is incomplete.

Installation condition is unstable.

Distan

ce be

tween transmitter and receiver exceeds

rated distance.

Beam is interfered with beam from another detector.

There is an electrical noise source in nearby area .

Sunlight enters receiver within

There is a highly reflective wall in parallel with beam.

No ala

rm is o

utput even when

beam is interrupted

Reflectance of floor surface is high.

Beam is interfered with beam from another detector.

Height of installation position is inappropriate.

<Note>

If the trouble remains unsolved even after taking above solution, please consult the dealer of your purchase .

2. Using a level LED

Rough adjustment

While looking into the scope located in the center of the

lens 10 to 15 c m away from it, turn the turntable for adju-

stment in the horizontal direction and the vertical adju-

stment

screw for adjustment 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.

Solution

Remove obstacle.

Perform optical axis alignment again to obtain 0.81V

or more tester level.

Stabilize installation condition.

Change installation position or use other detector with

suitable rated distance.

Take proper measure to avoid beam interference.

Replace transmitter and receiver.

Adjust optical axis so that it is on the other side of

reflection surface.

Adjust optical axis so that it is on the other side of

3. Using a tester

Fine adjustment

Insert the tester stick into the tester hole in the receiver to check

the tester voltage.

If the measured value is 0.81V or more, adjustment is completed.

To avoid the mutual interference of beams,please set the beams at different channels,

when installing more than one pairs at the same time.

MAINTENANCE

Be sure to perform periodical inspection at least annually.

Check items

• Tester level: Check that the tester level is 0.81V or more.

• Power input voltage: Check that DC

• Operation: Referring to

OPERATION CHECK

1. Alarm Operation

To check the alarm operation, actually walk along as-

sumed intrusion path near the transmitter and receiver,

respectively and in-between as shown in the figure be-

low.

Check that the alarm LED lights up and the controller

Scale 4~5

receives the alarm signal when the beam is interrupted.

Slow moving

2. Tamper Operation

Slow action

Check that the controller receives an abnormal signal

(0.2~0.5m/s)

when either of the transmitter and receiver cover is open.
