Takex MW-50L Instructions Manual

1) DO'S AND DON'TS 2) Height of installation

Install the unit at a height of 3.3' (1m),
ground to center of microwave sensor,
to detect human being walking or
running through the beam.

・Do not install the unit at places

where it may be blocked by
obstacles such as trees.

・Do not install the unit a street side

or in parking lots where many cars
may pass by. Installation must be
at 5ft. (1.5m) away from the
automobiles trafc.

・Do not install the unit on

unsteady surfaces.

・When installing the unit along

the side of a building or fence,
installation must be at least

3.3ft. (1.0m) away from said
constructions.

A core detection area is approximately φ2' (0.6m) as indicated
above as A, when the alignment is correctly adjusted. It is
suggested to make at least 3.3' (1m) open space on either side of
detection area to prevent faise alarm.

＊Please check the detection area by walking test.

Do not stack the sensors vertically.

(1m)

3) Check the environment of the installation site

The microwaves are affected by electric waves reected from
buildings, fences, and or the ground.
The beam reception level of the microwaves depends on how the
unit is installed in the area, especially by the height of installation.
Find the position
(height) of the sensor
for transmitter and
receiver respenctively
where the maximum
signal reception level
can be obtained
before the nal.

PARTS DESCRIPTION

InstructionManual

We appreciate your purchase of the TAKEX microwave sensor. 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 or a crime preventing device.
TAKEX is not responsible for damage, injury or loss caused by accident, theft, Acts of God (including inductive
by lightnin surges), abuse, misuse, abnormal usage faulty installation or improper maintenance.

MICROWAVE SENSOR

MW-50L

This Product consists of a transmitter which sends 24GHz band of microwave and a receiver which receives the beam. It will initiate an alarm
signal when the receiver detects a drop in the beam reception level due to interruption of objects interrupt between the transmitter and receiver.
Compared to a photoelectric beam, the wavelength of microwaves is extremely long, which prevent the sensor from being affected by weather such
as torrential rainfall, snowfall, fog or frost especially during cold winters. Stable detection performance is possible.
Two types of frequencies, MW-50H and MW-50L are available.

Receiver：Alarm LED

Optional (BP-50MW)

Install the sensor at a proper height and position otherwise
detection area could be widened over 6.6' (2m).
This could cause the sensor to detect movements of cars or
vegetations near the area and lead to frequent false alarms.

Note:

●

Don't install this unit in location
where it is exposed to direct
sunlight or halogen light. It may
become a cause of malfunction.

Don't face the mirror unit to the
sun directly during installing or
replacing.It may become a
cause of malfunction.

Don't install other than
correct direction.
(at slant, at upside down)

It is buried in snow
etc.

Freezing

1) Basic connection

The equipment must be powered from an LPS in accordance with EN60950-1 : 2001

2) When two or more sets are connected to
the same line.

3) When two or more sets are connected
to separate lines.

Wiring

When two or more sets are used, two frequencies (L and H types) should be used in order
to avoid cross talk or interference. Refer to the following example.

H type should be used for TR3 and RE3 when TR1 and RE1 are L type.

Do not install the transmitter and
the receiver at a same corner.
Microwave sensor with the same
frequency can be used for this case.

Mounting

2) Detach the mounting plate to
loosen 2 screws that x sensor
body to the mounting plate.

1) Detach the sensor cover with a
screw driver.

①Make holes in the wall.

・Place the mounting plate the wall as a template for drilling

and mark the screw holes. (Allow a space of 1" (25mm)
above and below the plate.
This will provide easy detachment of the cover after
installation.)

②Install the sensor.

・Insert tapping screws to 0.59" (15mm) under the screw head.
・Install the mounting plate on the wall after pulling the wire

through it.

・Connect terminals.
・Attach sensor cover.

②Install sensor on the pole.

・Attach the U brackets to pole and x the mounting plate

with screws.

・Fix the sensor the body to the mounting plate.
・Connect the terminals.
・Attach the sensor and pole covers.

(Break the knockouts on the cover and pole cover to adapt
to pole's diameter and conguration.)

・Attach the two U brackets to

the poles, one on top of the
other, facing opposite
directions.

(See illustration.)

①Make a wiring hole in the pole. Pull

the wire through wire.

Use plug etc.

1) Supply power with covers off.

2) Look through the view nder on the transmitter unit and move it until
the receiver unit is visible.

Repeat the procedure on the receiver unit.

3) Set the adjustment mode switch on the receiver to "adjustment mode".

Connect the digital volt meter to the monitor jack and check the monitor

output voltage (beam reception level).

When the output voltage is low, adjust the installation height of the

transmitter and receiver so that the output voltage will reach the
highest level. (Make sure that the angle of the antenna does not change.)

4) After adjustment, make sure that the adjustment switch is set to
"Operation mode".
