Check to see that
power cables are
properly connected and
polarity is correct.
NG
Correct terminal

an alarm signal generated.
The RECEIVER may be
affected by other beam
TRANSMITTERS, or the
beams are being refl ected off
of a shiny surface.
When the mirrors of the
RECEIVER are completely
covered, an alarm signal is
generated.
The beam interruption time is
set too long.
The intended target does not
block both upper and lower
beams completely.
Check to see that input power is
within the product's requirements.
AX-250PLUS/500PLUS:10.5-30VDC
AX-350TF/650TF:10.5-30VDC
NG
YES
Does the power supply output more
than 12VDC?
OK
Remove the alarm circuit wire
from the RECEIVER, and
check for short circuits on the
wires.
NG
Call Technical Support.
Are there any other outdoor
beams near the installation
site?
Are there any surface
OK
between the TRANSMITTER
and RECEIVER that are
refl ecting the beam?
NG
Remove the alarm circuit wire from the RECEIVER, place your volt
meter on resistance and measure the alarm output relay. Does the
relay open when power is removed?
Call Technical Support.
Turn the interruption time adjustment dial counter-clockwise one
graduation.
Does the RECEIVER work when both upper and lower beams are
completely blocked? If so, the installation height is not proper.
Adjust the installation height.
OK
Call Technical Support.
There is a possibility that
the power line has been cut.
NO
Remove the power wires
YES
from Power supply's output
terminals.
Measure the voltage. Does
the power now satisfy the
requirement?
NO
OK
Is the control panel zone's
"Loop Response Time" set to
within 1 second?
NG
Re-wiring of the alarm circuit
wire is required. Replace or
repair as necessary
YES
Remove power from all other
TRANSMITTERS and conduct
walk test.
NO
Does the Photoelectric Beam

work properly?
YES
Adjust vertical and/or horizontal alignment in order to move the
IR energy off the refl ective surface. Monitor the beam strength
(Monitor Jack) while adjusting beam to insure stable alignment.
NO
Check other items.
NO
The unit may be affected by electrical noise. May need to use
shielded wire and/or metalic conduit pipe. Call Technical Support
if you are unsure of the proper shielding techniques.
11
Disconnect power cable from the power supply and the
Photoelectric beam and test for short or open circuit. Also test for
short circuit to ground.
Repair as required.
Power cables may be too long for the gauge being used. This will
cause the voltage to drop. Use heavier cable or use additional
power supplies closer to the farthest units. If you are unsure of the
proper wire gauge, call Technical Support.
The power line is short circuited or grounded.
Repair as required.
The power supply may be malfunctioning, repair is required, or
call power supply manufacturer.
OK
The control panel may be
malfunctioning, call the control
panel manufacturer.
NG
Re-program the Zone's "Loop
Response Time" appropriately.
"Change the lay-out of the beams
or call Technical Support for
further advice."
AX-250PLUS/500PLUS
YES
Which AX is used?
NO
AX-350TF/650TF
Check other items.
If AX-350TF/AX-650TF beams are
used at the installation site, select
different "Frequency Channels"
for the beams causing the
interference.
YES
