InstructionManual

Thank you for purchasing the TAKEX product.

This sensor will provide long and dependable service when properly installed.
Please read this Instruction Manual carefully for correct and effective use.
Please note : This sensor is designed to detect intrusion and to initiate an alarm ; it is not a burglary-preventing device.
TAKEX is not responsible for damage, injury or losses caused by accident, theft, Acts of God (including inductive surge by lightning),
abuse, misuse, abnormal usage, faulty installation or improper maintenance.

This sensor consists of a transmitter that emits infrared
beam and a receiver that receives it.
As illustrated below, the infrared beam emitted from the
transmitter are reflected in the direction of incidence and
then enter the receiver.
A protection loop is formed in the route of the transmitter
reflector receiver.
Whenever this loop is interrupted (if any object should
interrupt the infrared beam), it is detected and an alarm is
initiated.

When a magnetic switch or the like is used in the circuit, insert it in
the section . For more details, refer to instruction manual for
control panel.

The dotted lines indicate connections for additional sensors installed.

Remove the terminal cover. Connect the wires with the corresponding
terminals correctly as instructed on the back side of the sensor. Break the
knockouts if necessary.

Supply power to the sensor.
If the sensor faces the reflector properly, the
operation LED does not light. If the LED lights,
refer to 4. INSTALLATION and re-adjust.
Next, interrupt the path of infrared beam
between the sensor and the reflector with beam
shielding objects (human body or the other objects
which interrupts infrared beam), and confirm
that an alarm is given and the operation LED is
ON.
If the alarm stops when this object is removed
(LED off), the system is working correctly.
Regular maintenance and inspection by installer
and frequent testing by user are vital to
continuous satisfactory operation of any alarm
system.

Symptom

No alarm condition

Continuous alarm

Frequent alarm with
no intrusion.

Possible cause Remedy

①Breaker of control panel is

cut off.
(No voltage on power
terminals for sensor)

②Either sensor or reflector

is not set in a correct
direction.

③Disconnection or

separation of wiring
between sensor and
control panel.

Infrared beam filter of the
sensor or the reflector is
stained with water drops,
dust, or the like.(Alarm may
be given continuously in
severe cases.)

Moving objects in the
protected area.(like curtain,
animal, etc.)

Clean the filter or the
reflector with soft cloth.

Remove the moving objects
from the protected area.

Recover the breaker.
(Search the cause of cut-off
of breaker)

Correct the direction of the
sensor or reflector with
reference to 4.
Installation of reflector.

Repair the disconnection or
separation.

Where the sensor is installed on a rough,
irregular surface like concrete, use a steel
plate of about 2mm in thickness as
foundation to prevent misalignment of the
optical system.

(Install the sensor facing the direction to be
protected.)

Install the reflector within the range of 2' (0.6m) to
15' (5m) from the sensor.
Note that the installation angle as well as the
position of the reflector. (See Fig. 2.)

Confirm that the sensor faces correctly to the
direction to be protected, then turn on the power
source. When power source is on, the operation
LED lights up.
Turn the reflector to the sensor and move it to look
for 4 positions in every directions where operation
LED goes out. The reflector is to be installed in the
center of the 4 positions.
Install the reflector as shown in Fig. 1.

The reflector has the function of reflecting infrared beam
in the direction of incidence within ±15°of the
incidence angle. When the reflector is tilted, be sure to
use it within the above range.

Installation of reflector

Angle of incidence should be within 15 degrees.
