through wirings.
It may stand 10000V under normal mode,
15000V under common mode.
Vertically ±20˚ compared with previous version.
It may adapt to the slope installation  exibly.
Enables better and clear view for easy beam
alignment.
This device is an opposed type photoelectric beam sensor that consists
of a photo transmitter that transmits infrared light, and a photo
receiver for the transmitted light, as shown in the illustration on the
right.
The infrared light transmitted from the transmitter expands in a cone
shape, while the light beams enter the receiver.
The straight line that connects the transmitter with the receiver is the
detection line.
If the detection line is obstructed (light is obstructed for more than
0.05 – 0.7 seconds), the receiver detects this break in the light beams,
and outputs a signal.
In order to ensure that the detection line has sufcient margin of
sensitivity, adjust the direction of the light beams before placing the
system into operation. Providing sufcient margin of sensitivity
reduces the occurrence of malfunction caused by dense fog, heavy rain,
frost, snow, and other such weather conditions.
Double modulated beams are designed to
distinguish the external lights.
It increases the reliability in the outdoor security
system.
The pitch between upper beam and lower one is
widened more than old models.
False alarm by birds and falling leaves reduces
drastically.
The beam power is 100 times of the minimum
requirement.
The beam distance is 10 times of the described
specication.
This high power beam also realizes the reliability
against the harsh conditions like fog, snow, heavy
rain.
50% less than remaining models. The battery size
may reduce, wiring diameter may lessen,
installation cost may decrease.
RoHS adapted – Environment friendly. Free from
Lead, Mercury, Cadmium, Hexavalent chromium,
Polybrominated biphenyl, Polybrominated diphenyl
ether.

Indicates information that if ignored and the device is handled incorrectly, may result in injury or damage to property alone.
This symbol indicates a prohibited action, with the specic action shown near the symbol.
Indicates the useful information.
Example: Do not disassemble
Warning
Caution
(1) When using multi-level protection, use sensors of the same model for both upper and lower sensors, and set the
same transmission power (H/L) for all of them.
(2) Using these sensors together with sensors from a different series (e.g. PB-HF-KH) may cause interference between
the sensors.
Do not install this device in a location that cannot support its
weight. Doing so may cause the device to fall and cause an
injury or malfunction of the device.
Installation in locations
shaded by trees etc.
Installation in location where
strong light such as sunlight or
light from vehicle headlights can
directly enter the receiver
Installation in areas where
objects that move with the
wind (the laundry etc) can
obstruct the optical axis

3
MOUNTING HEIGHT
3-2 As these sensors are designed to detect humans, install so that the center of the sensors are at a height of
approximately 2.6ft (0.8 m) from the ground when installing both on a wall and on a pole.
PRECAUTIONS In order to use these sensors correctly, thoroughly read this instruction manual and select the mounting position and
protection distance.
A: Protection Distance
165ft ( 5 0 m )
330ft (100 m)
660ft (200 m)
Approx. 4ft (1.2 m)
Approx. 8ft (2.4 m)
Approx. 16ft (5.0 m)
B: Coverage of light beam
Installing so that the center of the sensor is
approximately 2.6ft (0.8 m) from the ground means
that the protection line is at waist height for
humans, enabling reliable detection.
If the installation position is too high or too low, the
protection line will be above shoulder height or below
knee height, making it more dif cult for reliable
detection.
WRONG
CORRECT
1. In areas where there are trees or weeds, the infrared may get obstructed by overgrown branches or leaves.
As this may cause erroneous detection, be sure to trim down leaves and branches according to the growth of the plants.
Furthermore, the infrared may get obstructed by swaying branches or leaves due to wind. Keep in mind the swaying of leaves and
branches when trimming them.
2. Vine type plants may wrap around the photoelectric beam sensors causing erroneous detections. Therefore, be sure to prune such plants
regularly.
3. Other natural phenomena such as insects or bird droppings may soil the sensors causing miss detection. Be sure to clean the sensors
regularly.
Cautions when using the outdoor photoelectric beam sensor (Daily maintenance)
Installation on uneven
ground
Slanted installation Overhead wiring Installation close to a wall
Installation in locations where the
unit may be splashed by dirty
water or direct sea spray
Using PXB-HF-KH together with other
beam sensors or different protection
distance beam sensors in stacking
Installation directly above
a wall
Installation in an
unstable, wobbling location
PROTECTION DISTANCE AND
RANGE OF LIGHT BEAM COVERAGE
3-1 As the infrared light leaves the transmitter, it expands into conic shape light beams.
The optical axis is in the center of the light beams. Arrange the reflector so that the
device on the opposite side is in the center of the light beams.
If the optical axis is not aligned correctly, there will
be insufcient margin of sensitivity even if the
receiver is at the center of the light beams, making
the system more susceptible to adverse effects of the
environment resulting in a malfunction.
If the optical axis (center of the light beams) is
aligned correctly, a detection line with sufcient
margin of sensitivity is formed.

Accurate adjustments of the optical axis can be achieved by checking
the light reception level value using the voltage of the monitor output.
<<Caution>>
First, check only the transmission on the upper level and reception on the upper level , and then check only the transmission on the
lower level and reception on the lower level.
(The values are not displayed correctly when the light can be received for both the upper and lower levels.)
1. Insert a commercially available tester into the monitor
jack on the receiver.
<<Caution>>
The monitor jack is polarized.
Check the polarity of the tester pin before inserting it.
Use a tester with an internal resistance of over 100 kΩ.
2. Fine adjust the upper level optical axis.
(1) Press the upper/lower changeover switch
on the transmitter to select [Only transmit
from upper].
(2) Press the upper/lower changeover switch
on the receiver to select [Reception
authorization on upper only].
(3) Turn the adjustment screw to ne adjust
until the monitor output voltage reaches
the highest value.
(Adjust both the transmitter and receiver.)
3. Fine adjust the lower level optical axis.
(1) Press the upper/lower changeover switch
on the transmitter to select [Only transmit

4. Check if the light from another transmitter enters the receiver.
(1) Press the upper/lower changeover switch on the transmitter to
select [No transmission].
(2) Press the upper/lower changeover switch on the receiver to
select [Reception authorized for both upper and lower].
(3) Check that the alarm LED lights up when the receiver
outputs an alarm signal, and that the sensitivity attenuation
LED also lights up. Also check the monitor output voltage.
If no alarm is activated or the sensitivity attenuation LED is not lit
When using multi-level protection, the monitor output voltage
may become close to “1 V” due to effects of other photoelectric
beam sensors. In such case, readjust the other photoelectric
beam sensors to reduce the effects to the minimum possible.
In addition, check that an appropriate channel is set.
Accurate adjustments of the optical axis can be achieved by checking the light reception level value using the voltage of the monitor output.
As the light reception level value can also be checked using the voltage on the transmitter, more accurate adjustments of the optical axis can be
achieved.
Using the alignment wireless checker enables easy and accurate beam alignment.
Providing sufficient margin of sensitivity increases resistance to the dense fog, snow, and heavy rain, which makes it possible to construct a
highly reliable intrusion alarm system.
Note: For detailed operation procedure of the alignment wireless checker, refer to the instruction manual for the alignment wireless checker ER-02.

Set Transmitter LED switch of the transmitter to [OFF] and mount the cover (housing).
When Transmitter LED switch is set to [OFF], the LED light turns off, but the upper
and lower beams are transmitted.
After the optical adjustment is completed, set Auto Gain Lock switch
to [ON] under the light beam reception condition, and wait for
approximately 5 seconds.
During this period, do not shield the optical axis.
A one-time short beep sound [Pi
- ] shows that the auto gain lock is
completed correctly.
(After the auto gain lock, the upper and lower LEDs light off.)
Set Reception authorization LED switch of the receiver to [OFF].
Obstruct the sensor beams near the sensor or the center
of the detection line and check that an alarm can be
output correctly.
In using the environmental output,
conrm that the environmental output
is generated when the optical axes in
both the upper and lower sections are
shielded for 20 seconds or more.
If the sound check switch is set to ON, after the auto gain lock
has been completed normally, the walk test mode is activated
for 5 minutes. The beep sound is generated in synchronization
with the alarm output.
The alarm LED lights up according to the alarm output.
After the auto gain lock is completed correctly, the walk test mode is activated
for 5 minutes regardless of whether the cover is mounted or not. During the
walk test mode, the beep sound is generated when the alarm LED lights on by
the alarm output. After approximately 5 minutes has elapsed, the walk test
mode ends. Even if Auto Gain Lock switch is not set to [ON], set Reception
authorization LED switch to [OFF] activate the walk test mode for 5 minutes.
How to set Auto Gain Lock by remote control.
The units has terminals for Auto Gain Lock by remote control.
1. Attached the housing cover of receiver side.
*Set the Auto Gain Lock switch “OFF” and set the Auto Gain Lock terminal
“Open”
2. Change the Auto Gain Lock terminal to “Close”, and wait for 5 sec.
If a “beep” tone sounds once after 5 sec. the Auto Gain Lock is completed.
*Don’t block the optical axis while 5 sec for initialize.
The intermittent beep sound like “PiPiPi........” shows
that the beam reception volume is not enough. In this
case, the LED on the side of the insufcient reception
volume blinks. Set Auto Gain Lock switch to [OFF], and
adjust the optical axis again.
In the multi-level protection, when the light enters from
other units than the opposing transmitter, turn off the
power of the other transmitter to stop transmitting the
light beam, then set Auto Gain Lock switch to [ON].

The margin of sensitivity on this device is set so that an appropriate sensitivity can be obtained when the optical axis is aligned while the
device is installed in the maximum protection distance. However, if the actual distance is shorter than the maximum rated protection
distance, excessive margin of sensitivity is secured, which could make the device more susceptible to adverse effects of the reection from
the ground or walls. The auto gain lock function helps to adjust to an appropriate margin of sensitivity and x the setting in the same
manner as when the device is installed in the maximum rated protection distance, regardless of the actual installation distance (below the
maximum rated protection distance). (However, it is always required that the optical axis is correctly aligned.)

During adverse environmental conditions such as dense fog or heavy rain, this function temporarily increases the sensitivity of the
receiver.
Note: The margin of sensitivity is maintained even if there is a sudden worsening in weather conditions.
The LED lights up when the light reception level is considered to be insufcient
in order to notify the operator of that an inspection is necessary.
The light reception level falls below the specied level under adverse environmental conditions such as dense fog or heavy rain. This function issues
an environmental output if such conditions are maintained.
Note: The environmental output continues until the light reception level for both the upper and lower beams recovers to the specied level (for 5
seconds at the shortest).
Using the alignment wireless checker that is sold separately enables easy and accurate optical axis adjustment.
Providing sufcient margin of sensitivity increases the resistance to the dense fog, snow, and heavy rain, which makes it possible to construct a
highly reliable intrusion alert system.
