1. INSTALLATION GOOD PRACTICE
[2] Do not install the unit
where objects moved by the
wind such as plants and
laundry, which may block the
beam.
[1] Mount unit only on a solid
surface.
The following items are important to ensure the performance of the product. Be informed that the detector may not detect
objects if not installed correctly.
[4] Mount the units in such
a way that the infrared
beam of any other model
does not enter the
Receiver.
[6] The mounting pole should have a
solid footing.
[5] Avoid aerial wiring. [7] Ensure that the mounting distance
between the Transmitter and the
Receiver (maximum detection range)
is within the rating.

·In order to obtain the optical alignment accurately, apply the supplied optical reduction plate on
the both upper and lower beams of one of the transmitter or receiver. Use the optical reduction
plate according to installation distance. Remove the plate after the optical alignment is completed.
7. OPTICAL ALIGNMENT
7-1. Aligning the optical axis
·Optical alignment is an important feature for maximizing the reliability of the product. Follow the instructions
given in 7-2 to 7-5 in this chapter and make adjustment in such a way that the maximum voltage of the monitor
jack is confirmed with the level indicator.
·Be sure to start optical alignment with the top beam .
The level indicator of the Transmitter may not work if the beam
at the top level is not aligned.

Make sure that the covers of both the Transmitter and the Receiver are open (the rubber bushings are not
inserted for AX-350DH BT) when setting the switches.
Models AX-350DH TS and AX-350DH BT allow switching between top/button level AND and OR detection modes.
Using the OR detection mode is effective for detecting smaller human objects such as ingress by crawling.
Be informed, however, OR mode may cause an increase in false alarms due to flying debris or small animals, care should
be taken to ensure that all factors are considered when selecting OR mode.

Level indicator alignment is needed after the optical alignment is completed through viewfinder.
7-3. Rough alignment by viewfinder
Be sure to adjust both the upper and lower mirrors.
While looking through the viewfinder on the left or right of the mirror, turn the dial to make alignment in such a way that
the other detector is at the center of the sights.
Note
Vertical Alignment Dial Horizontal Alignment Dial
7-4. Adjustment with level indicator
Fast flicker
Slow flicker
After the rough alignment using the viewfinder, make sure that one or more
level indicator LEDs are illuminated or flickering for both the top and the
bottom levels. If not, make adjustment again with the viewfinder.
In the rough alignment mode, each
LED of the level indicator switches
from the flickering to the continuously
ON state as the level of light reception
becomes higher.
[1] Checking of illumination of the indicator
[2] Adjustment in the rough alignment mode
Make optical alignment until the level indicator LED at the “Good” position
is illuminated. At this time, the level indicator LEDs at the lower positions
remain illuminated. This condition is called the rough alignment mode.
Be sure to start rough alignment
with the upper mirror. Otherwise
the level indicator of the
Transmitter may not work.
Continuously ON
Note
Once the level indicator LED at the “Excel” position is illuminated, all of the
LEDs start flickering fast together, which indicates that the mode is switched
to the fine adjustment mode. The level indicator LEDs at the lower positions
do not remain illuminated in the fine adjustment mode.
[3] Switching to the fine adjustment mode
Depending on the accuracy of the rough alignment by viewfiner, the beam adjustment
may be started from fine adjustment mode without rough adjustment mode.
Note
It may not change to fine adjustment mode when the detector is used with maximum
distance.
[4] Adjustment in the fine adjustment mode
When the mode is switched to the fine adjustment mode, the level indicator LEDs start flickering and
the indication point falls.How far the indication point goes down depends on the situation. Finding
the peak position in this condition allows fine-tuning.When the level of the “Excel” level indicator LED
exceeds the flickering level in the fine adjustment mode, all of the LEDs start flickering together again
and the indication point falls automatically. Repeat this until the alignment peaks.
Note
In the fine adjustment mode, the indication point may not reach the “Excel” position. This
indicates fine adjustment condition above the “Excel” position, which means that it causes
no problem in operation.

Relation between monitor jack output and beam achievement level
Level of received light can be checked with voltmeter same as level indicator performs.
[2] Check the alignment level with volt meter
Make the optical alignment to reach its peak after the alignment through viewfinder is completed.
First of all, the monitor jack level has to be over 2.9V(AX-650DHMK III requires over 2.2V) when the optical alignment is
completed. This is equivalent to the rough adjustment mode by the level indicator.
[3] Peak Find Adjustment
Check the alignment level with volt meter to ensure that proper
alignment has been achieved. Switch the monitor jack switch
to make sure that the voltage from both upper and lower beam
is over 0.3V.
Readjustment through viewfinder is required in case of the
voltage is under 0.3V.
monitor jack switch
The condition of the monitor jack being outputted over 3.4V is called “fine adjustment mode”.
Furthermore, if the optical alignment is adjusted continuously and a monitor jack output achieves to 4.8V, the output value
of a monitor jack will fall automatically.
In order to obtain the finest adjustment, this operation executes repeatedly.
In fine adjustment mode, the monitor jack output may not achieve 4.6V but there is no problem using the detector with this
condition because the beam is in the state more than the superior position in rough adjustment mode when the optical
adjustment mode switches to fine adjustment mode.

[1] Preparing the voltmeter
Depending on the accuracy of the rough alignment by viewfiner, the beam adjustment may be

Note
Be sure to start rough alignment with the upper mirror. Otherwise the level indicator of the Transmitter may not work. Note
It may not change to fine adjustment mode when the detector is used with maximum distance.

After the rough alignment using the viewfinder, make
adjustment with the monitor jack for more accurate
optical alignment. Set the voltmeter range to 5 to 10
VDC and connect the voltmeter probes and to
and of the monitor jack respectively.
