Installation Instructions
For best performance, you should consider the followings when placing, installing and keeping the product at a distance from
the object.
• Do not expose it to a place where its light projector or light receiver is affected by a direct strong light such as sunlight or
headlight. (below ±2 is not allowed in the optical axis)
• Do not install it in an unstable, not properly secured place. (wire fence or unsecured pole is not allowed)
• Do not install it in a place where the infrared light is blocked due to a seasonal reason such as thick wood or bushes.
• Keep it away from the muddy water or sea water keeping splashing. (the infrared light is likely to be blocked by the muddy
water or sea water)
Installation
To mount on the wall
1. Loosen the screw to remove the cover of the sensor as shown.
2. Attach the plate to the wall and mark the hole position, then drill a hole and
use the screws (4mm) to fix the plate.
3. Remove the slot-shaped filling on the rubber hole of the sensor and
pull out the cables through the hole.

Rubber Hole
4. When done, adjust the optical axis and insert the cover.
To attach to the pole
1. Pull out the cables from the wiring hole of the pole; insert the
U-shaped pole bracket to the pole
Cable-In Hole
2. Attach the sensor to the bracket and arrange the cables as
necessary.
Pole Bracket
(optional)
 same as in wall-mounting
3. Put the cover as original.
 Pole external diameter: Φ38~Φ46
Channel Setting (SIA-0120D)
To prevent misalarming due to possible frequency interference between two or more sensors in one place, set the channel
respectively.

Adjusting the response speed
You can adjust the response time by turning the response time control wheel left or right.
Turning it left will speed up the response time; turn it right to slow down the time.
 The factory default is set to 250 msec.

Adjusting the optical axis
1. Connect both transmitter and receiver and turn them on.
2. Look through the mirror of the sight and adjust the
sensor so that the other sensor can be positioned in
the center of the mirror.

 You can use the left/right adjustable screw and
the vertical adjustable screw of the reflector to
refine your adjustment.

3. Check the level of the light received from the monitor output signal.
You can use the tester to measure the DC voltage and refine your adjustment.
4. Check the output voltage of the tester and close the cover.

To be adjusted
Using the attenuation film for optimal adjustment of the optical axis
1. Attach the attenuation film to the reflection part of the receiver in order for finetuning after the initial optical axis adjustment.
2. Make adjustment until the “Good LED” turns green.
3. Remove the attenuation film and close the cover.
 The attenuation film is a special film designed especially for blocking the
external light from the transmitter by 90% and allowing inflow of only 10%.
