SUGGESTIONS FOR INSTALLATION
Do not install in the following conditions:
Ensure the sensor’s line of
sight is free from any false
alarm sources such as
bushes, trees, etc. (Pay at-
tention to these as they may
change seasonally).
Ensure the sensors
are mounted on a
stable and firm foot-
ing.
Ensure strong sunlight or
car headlights do not shine
directly on to the receiver.
(Within ±2° from the optical
axis is not recommended).

ADJUSTMENT OF OPTICAL AXIS
(Aiming Beam)
1. Remove transmitter and
receiver covers and apply
power to the units.
2. In each unit, remove the
viewfinder from it’s normal
storage location and place
it, as shown, on one of the
holders on either side of the
lens. Use whichever side
permits sighting through the
viewfinder in the next step.
3. At the transmitter, look through the
viewfinder, with your eyes about 10 cm.
From it. Adjust the horizontal angle
bracket and (with a small screwdriver)
the vertical angle screw. When the
transmitter’s optical axis is properly
adjusted, the image of the receiver will
be seen in the center of the viewfinder.
4. Repeat step 3, but at the receiver.
When the transmitter’s image is seen in
the center of the receiver’s viewfinder,
the receiver’s GOOD (green) monitor
LED should be on as confirmation of
proper alignment (if off, carefully repeat
steps 3 and 4).
NOTES:
The brightness of receiver’s
LE EL (red) LED will vary with
the accuracy of alignment. The
better the alignment, the brighter
the LED.
ertical Alignment
To Raise To Lower
The best adjustment of optical axis can be done by reading the output
voltage of the monitor jack.
1. Insert the meter pins into the monitor jack. (Pay attention to the polarity
because of DC voltage.)
2. a) Adjust the horizontal angle bracket until the output is at maximum.
b) Adjust the vertical angle screw to obtain maximum signal. (Do not
interrupt beam by hands during the adjustment.)
3. The minimum voltage (2.3 ) should be obtained to ensure best perform-
ance. (If this is not obtained then Transmitter and Receiver should be
re-aligned.)

ADJUSTMENT OF SHADING TIME
Set the obscuration time of the receiver by
adjusting the obscuration time control to the
required setting according to the sketch to the
right.
The obscuration time should be set lower to
detect faster moving targets, however care
should be taken to note the environmental con-
ditions as the obscuration time should be set
higher to ignore conditions where there are a
lot of birds or wind-blown material.

TROUBLESHOOTING GUIDE
Symptom Possible Cause Remedy
Transmitter LED does not light. Improper voltage supplied. Check power supply and wiring.
Receiver power LED does not light. Improper voltage supplied. Check power supply and wiring.
Alarm LED does not light, even when
beams are blocked.
Infrared beam from transmitter is reflect-
ing from another object and is being sent
into the receiver.
Remove reflecting object or change in-
stallation location and optical axis direc-
tion.
Two beams are not blocked at the same
time.
Check two beams to assure blocking at
same time.
Shorter blocking than the time set. Adjust blocking time to be longer.
Although Alarm LED lights when beams
are blocked, alarm doesn’t sound.
Broken or shorted alarm output wires. Check the wiring.
Blown fuse on the signal circuit. Repair as required.
Alarm LED on receiver does not turn off. Optical axis not aligned. Readjust the optical axis.
Blocking object between transmitter and
receiver.
Remove the blocking objects.
Dirty cover or reflecting mirror at trans-
mitter and/or receiver.
Clean optics with soft cloth.
Bad wiring connection. Check wiring connection.
Change of supply voltage. Check for stabilized voltage.
Blocking objects blowing between trans-
mitter and receiver.
Remove blocking objects or change
installation location.
Unstable sensor mounting. Stabilize mounting.
Marginal optical axis alignment. Readjust the optical axis.
Birds or other large flying objects inter-
rupting the beams.
Readjust blocking time or relocate instal-
lation.
