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 traffic.

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 

φ

2' (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.

3.3'

(1m)

3) Check the environment of the installation site

The microwaves are affected by electric waves reflected 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 final.

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.

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.
