The detection area depth can be changed by
the area adjustment tool.
When adjusting the 1st to 3rd rows close to the door, follow 3-7 Installation mode.

Check the area position with Red LED of the Operation LED using a tool such as a reflecting mirror.
Make sure the detection area does not overlap with the door / header,otherwise ghosting / signal saturation
NOTE NOTA
may occur.
Do not place any highly reflecting objects in the detection area, otherwise signal saturation may occur.
REFERENCE
Area depth adjustment with INFRARED FINDER (Separately available)
1. Turn the depth adjustment screw to the right (Deep) to place the area most away from the door.
2. Set INFRARED FINDER sensitivity to "H" (High) and place it on the floor as shown below.
3. Turn the depth adjustment screw to the left (Shallow) until the emitting area is placed at the position where
INFRARED FINDER is in the low detection status (Slow Red blinking).
1-2. Simultaneous adjustment
For the simultaneous adjustment of 1st to 5th rows, use the adjustment tool (C).

3-1 Setting the sensitivity
Normally set to "Middle". " Low" decreases the sensitivity and "High / S-High"
increases the sensitivity.
3-2 Setting the presence detection timer
The 1st and 2nd rows have the presence detection function.
The presence detection timer can be selected from 4 settings.
NOTE
To enable the presence detection, do not enter the detection area for 10 seconds after setting the timer.
3-3 Setting the frequency
When using more than two sensors close to each other, set the different
frequency for each sensor by combining dipswitch 5 and 6.

When setting motion and motion / presence detection area sparately, make sure that there is no gap between
two areas.
3-5 Setting the snow mode
Set this switch to ON, if the sensor is used in a region with snow.

3-6 Setting the immunity
Set this switch to ON, when less influence by the header vibration is required.
3-7 Installation mode
Use this switch to ON when adjusting the presence detection area
close to the door face.

INFORM BUILDING OWNER / OPERATOR OF THE FOLLOWING ITEMES
WARNING
1. Always keep the detection window clean. If dirty, wipe the window lightly with a damp cloth.
2. Do not wash the sensor with water.
3. Do not disassemble, rebuild or repair the sensor yourself, otherwise electric shock may occur.
4. When an operation LED blinks green, contact your installer or service engineer.
5. Always contact your installer or service engineer when changing the settings.
[m]
6. Do not paint the detection window.
NOTA NOTE
1. When turning the power on, always walk-test the detection area to ensure proper operation.
2. Do not place any objects that move or emit light in the detection area. (e.g. Plant, illumination, etc.)
