BEAM ALIGNMENT ADJUSTMENT
AND OPERATION CHECK
INSTALLATION WITH OUTLET BOX
Remove the cover from the
sensor unit by using a screw-
driver etc.
Install the sensor with M4 × 30 screws.
As for exposed outlet box, 1.95" (50mm) depth is required.
Turn the power on with the cover detached.
When the receiver's cover is removed, the sensor goes into
adjustment mode and its sensitivity will be automatically
decreased.
Adjust the windows of transmitter and receiver to face each
other.
Look in finder and adjust the counterpart to be located at
the center of the scope, by using vertical and horizontal
adjustments.
Repeat this procedure for transmitter and receiver as well.
Adjust untill the receiver's alarm LED (RED) goes off.
After the above adjustment, interrupt beam and confirm
that alarm LED lights on and an alarm output is issued.
To Conceal the alarm LED, detach LED masking rivet and
put it into the hollow of the alarm LED, as occasion requires.
After the above is compleated, attach the cover.
The sensitivity of the sensor will be automatically increased.
After attaching the cover, interrupt beam and confirm the
sensor's operation at the both sides of sensor and control
panel.
Make a hole 1.97" × 2.83" (50mm × 72mm) on wall and install
the sensor with the attached screws, 1.57" (40mm) depth is
required.
