OPERATION: 

 

 

The power and movement detection indication

: The LED will flash once every  4 seconds after 

power ON of the unit, and will flash every 2 seconds when the units detects the movement.  

 

Detection field

: The detection field is made up of up and down, left and right service field. (See 

the following diagram). But it has the relation ship between the sensitivity and the orientation of 

moving. Detection distance may vary according to the installation position and detection field. 

 

Time-delay adjustment

:  The timer knob can be set according to the customer needs. The 

minimum is 30 sec. and the maximum is 450 sec delay OFF.

 

 

 

Identifies day and night automatically

: When the trimmer knob is turned towards SUN Position 

(max), it will switch ON  lights both in  day and night. When turned towards MOON position (min), 

the sensor will operate only at night (less than 10LUX ambient light) 

 

Correct Moving Orientation

Incorrect Moving Orientation

At a distance closer to sensor the detection motion speed can 

be minimum and vice versa
