3. Alarm signal is being generated though beams are not blocked

Is the Alarm

Indicator LED on

the RECEIVER

illuminated?

“Refer to the following “Monitor

Jack Output" valnes to insure the

beams are properly aligned."

AX-250PLUS/500PLUS:5.0 VDC

or more AX-350TF/650TF:5.5

VDC or more

Note:

When using the LED alignment

indicator of the AX-350TF/650TF,

make sure the LED shows

“EXCEL".

Go to page 11, see trouble shooting procedure number 1.

Check the alarm circuit wires

for shorts, opens or grounds.

Also check the control panel

for proper function.

Remove any objects or move

the beams.

Remove the alarm circuit wire

from the RECEIVER, then

check the alarm output relay

with volt meter.

Is the LED indicator on the

TRANSMITTER on?

YES

Output is in alarm condition.

Double check to see that

there are no objects that may

be blocking the beams.

YES

Go to page 11, see trouble

shooting procedure number 1.

“Re-align the beams using a

volt meter to insure proper

monitor jack output voltage.

Does the value satisfy the

beams requirement?"

Output is in the normal

condition.

Does the Unit work properly?

Call Technical Support.

Completed.

Call Technical Support.

YES

4. False activations

“Re-align the beams

Refer to the “Beam

Alignment Procedure.”

Use the HU-1 heater unit.

“Turn the beam's interruption adjustment clockwise one graduation."

Cut off branches, now grass or secure debris to avoid

unnecessary activation. Or move the beams.

Adjust the interruption time, change the installation height or

move the beams in order to avoid perching birds within the

beam's path.

Adjust the interruption time, change the installation height or

move the beams in order to avoid small animals crossing the

beam's path.

Move the beams to avoid the rising or setting sun. Or swap

TRANSMITTER and RECEIVER locations.

Call Technical Support for other options.

Remove the objects causing the re

ection, or move the beams.

Call Technical Support for other options.

Check for shorts, opens grounds and high resistance values or

the alarm circuit wires. If everything looks to be OK, call Technical

Support for further testing measures.

Clean covers both inside and outside using a dry soft cloth or

mild soap and water only. Do not use any oil or alcohol based

solvents to clean the covers, doing so will cloud or etch the cover

and reduce its ef

ciency.

There is frost or snow on the unit's cover.

Very heavy rain occurred at the same time as the activation.

There are plants, trees or debris that may block the beam

during windy conditions.

The unit may be detecting a large bird.

The units may be detecting small animals (dog, cat, deer etc...)

The RECEIVER is facing directly at the rising or setting sun.

There are re

ective objects within 3 feets of beams path. (cars,

glass, surfaces with high gloss paints etc.)

Bad wiring or corroded splices. Check for shorts, opens,

grounds and high resistance on the alarm circuit wires.

The covers are very dirty or dusty.

Check alignment

voltage from Monitor

Jack. Does it

satisfy the minimum

requirement?

Are the beams

mounted on a stable

footing with little

movement of the

mounting structure?

Change footing, pole

or structure to insure a

stable mounting surface.

Important:

The majority of false activations can be attributed to
poor beam alignment. When aligning outdoor beams
accept no less than an “EXCEL" value for the most
stable and trouble free system!! Refer to the installation
manual for acceptable Monitor Jack Voltage Values.

Note: Beam Alignment Procedure

When aligning dual or twin beams you must cover both bottom receiver mirror and
transmitter mirror with blocking shields, than adjust the top attempting to maximize
the Monitor Jack Voltage (see below). When maximum voltage is obtained,
place the blocking shields on both upper receiver mirror and transmitter mirror
and adjust lower for maximum Monitor Jack Voltage. (Do not align both beams
simultaneously.)

AX-250PLUS/500PLUS:5.0VDC or more
AX-350TF/650TF:5.5VDC or more
When using LED INDICATOR of AX-350TF/650TF, align to get at least “EXCEL".

NOTE

These units are designed to detect an intruder and activate an alarm control panel. Being only a part of a complete system, we cannot accept
responsibility for any damages or other consequences resulting from an intrusion.
These products conform to the EMC Directive 2004/108/EC.
