IMPORTANT – Do not connect to power until the sensor is completely installed and the

installation has been double-checked.

Included:

Transmitter x 1

Receiver x 1 Mounting plates x 2

Mounting

hardware

also

included.

Pole mounting

brackets (2 sets)

Features:

Four selectable beam frequencies

(For E-964-D390GQ model only).

Twin beams provide reliable perimeter

security, minimizing false alarms from

falling leaves, birds, etc.

Lensed optics reinforce beam strength

and provide excellent immunity to false

alarms due to rain, snow, mist, etc.

Weatherproof, sunlight-filtering

case for indoor and outdoor use.

Non-polarized power inputs.

Automatically adjusts beam

strength to compensate for

different weather conditions

Automatic input power filtering with

special noise rejection circuitry.

NC/NO trigger output.

N.C. tamper circuit included.

Quick, easy installation with built-

in laser beam alignment system.

Situation

Transmitter LED does not light.

Receiver LED never lights up

when the beam is interrupted.

Beams interrupted and LED

lights, but no trigger output.
Trigger LED continuously lit.

Trigger becomes erratic in bad

weather.
Frequent false triggers from

leaves, birds, etc.

Solution

Ensure the power supply to the

transmitter is 12 to 30V DC/AC, 60Hz.
a. Double-check the voltage.

b. Clean the cover.

c. Check overall installation.
Check the continuity of the wiring

between the sensor and the alarm.
a. Realign the lenses.

b. Remove any obstacles.

c. Clean the cover.
Check overall system installation.

If still erratic, realign the lenses.
a. Reduce the response time.

b. Change the transmitter and/or

location.

Table 6:  Troubleshooting

Possible Problem

Incorrectly wired and/or

insufficient voltage
a. Insufficient voltage

b. Beam reflected away from receiver

c. Beams not simultaneously interrupted.
Trigger cable may be cut, or the

relay contact stuck due to overloading.
a. Lenses out of alignment.

b. Beams are blocked.

c. Cover is foggy or dirty.
Lenses out of alignment.

a. Too sensitive.

b. Bad location.
