Receiver Indicators
• GOOD LED (Green). Use when adjusting
beam alignment. ON when beams are
aligned, OFF when beams are not aligned.
(Refer to operation instructions)
• LEVEL LED (Red). ON indicates received
signal. Brightness varies, depending on
incident level.
• ALARM LED (Red). ON indicates beam
blocked. Use when setting response time.
(Refer to operation instructions)
Transmitter Indicators
• POWER LED (green). ON when light
beam is transmitting.

MOUNTING CAUTIONS
Do not mount the detector in the following conditions:
Where obstructions (plants,
fences, etc.) are between the
receiver and the sender.
Where sunlight and headlights
shine directly into the front of
the receiver.
Where the mounting
surface is unstable.

5. Connect wires to the terminals:
See wiring diagram, next page.
• Wire with 22awg minimum
• 300 ft (91 .4m) max length
• Be sure to capture the wire ends under the
wire clamp plates.
• Avoid frayed ends on wires that might
produce a short circuit.

Pole Mounting
1. Break out the wire hole on the
bracket then pull out the wires.
2. Remove the cover.
3. Attach the base plate on the
bracket using the Regular Ring.
DIP SETTING
NOTE:
1. DIP 1 & 2 on Transmitter & Receiver must be on the same position (same channel).
2. Dial the PIN 5 at “ON” position on Receiver. STARTUP time is about 0.06 seconds.

BEAM ALIGNMENT
1. Remove the cover, and turn ON
power.
2. Adjust the horizontal pivot, and the
vertical adjustment screw using the
built-in viewer.
3. Look through the peep hole on
either side and adjust to put the
opposite sensor in the middle of
the cross-hairs in the viewnder.

TROUBLESHOOTING
Symptom Possible Cause Remedy
Transmitter LED does not light.
Improper voltage supplied. Check the power supply and wiring.
Receiver LED does not light.
Alarm LED does not light, even
when beams are blocked.
1. Beams reect to the receiver by other
objects.
2. Both beams are not blocked simultaneously.
3. Beam block time is too short.
1. Remove the reecting object or
change optical axis direction.
2. Block both beams.
3. Increase beam block time.
When the beams are blocked, the
receiver LED light is ON, but not
alarm.
1. Wiring is short circuited.
2. Wiring connection is not good. Check wiring and connection spot.
The alarm indication lamp of
receiver is always on.
1. Optical axis is not properly adjusted.
2. There are obstructions between the
transmitter and the receiver.
3. The outer covers are dirty.
1. Adjust the optical axis.
2. Remove the obstructions.
3. Clean with window cleaner and a soft
cloth.
Intermittent Alarm
1. Bad wiring.
2. Fluctuating power supply/ voltage.
3. Intermittent blockage between the
transmitter and the receiver.
4. The receiver or transmitter is unstable.
5. Blocked by other moving objects.
1. Check wiring.
2. Check the power supply.
3. Remove the obstruction or relocate.
4. Fix the mounting.
5. Adjust the optical axis.
6. Adjust interruption time or change
installation position.
