Assembly

assembly left and right, and use the vertical
adjustment screw to tilt the sensor up and down.

NOTE 1: Correct alignment is reached when the red
LED turns OFF and the Green LED turns ON.

NOTE 2: If the LED alternately flashes green and
red, the sensor is at the edge of sensing the signal,
and may not work properly.

4. Put the object to be detected between the sensor
and reflector (in about the place where the object
would normally be detected by the sensor). The
green LED should turn OFF and the red LED will turn
ON).

Testing:

1. Power up the sensor. The green LED should be ON;
the red LED should be OFF.

2. Pass the object to be detected between the sensor
and reflector. The red LED should turn ON and the
green LED

should turn OFF. This indicates that the object

has been detected.

1. Unscrew the 4 screws and remove the cover.

2. Loosen the captive screw to free the sensor from
the mounting plate.

3. Using the included screws, mount the mounting
plate to the wall.

4. If the wires come from inside the wall, use the
breakout and rubber gasket on the back of the
sensor to run the wires. If not, use the breakout
and cable gland at the bottom of the sensor to run
the wires.

5. Remove the terminal block using long-nose pliers
and wire the unit according to the wiring diagram
above.

6. Hang the sensor back on to the plate, and use the
captive screw to secure it in place.

7. Re-attach the cover, and use the included small
screws to secure it.

8. Attach the hood to the top of the sensor.

Troubleshooting:

Trouble Remedy(s)Possible Origin(s)

Sensor does not detect the
object.

Green LED does not
turn on.

Red LED lights when object
is detected, but no output.

1) Sensor sensitivity is not properly set.

2) Object may have a reflective surface
which confuses sensor.

1) Dirty sensor and/or reflector.

2) Reflector and/or sensor is
misaligned.

No continuity between sensor and
alarm device.

Vertical
Adjustment

±5°

Change the angle of the sensor or
readjust the sensitivity setting.

1) Clean the sensor and reflector
with a damp (not wet) cloth.

2) Adjust the reflector and/or
sensor for proper alignment.

Check cable from sensor to alarm
device. Test sensor.
