PROBLEM
POSSIBLE CAUSE
SUGGESTED REMEDY
Light does not switch on when
there is movement in the
detection area.
1. No mains voltage.
Check all connections, and fuses/switches.
2. Globes faulty or missing.
Check. Replace.
3. Nearby lighting is too bright.
Redirect sensor or relocate the unit.
4. Controls set incorrectly.
Readjust sensor angle or control knob.
5. Sensor positioned in wrong direction.
Redirect sensor and/or adjust.
Light switches on for no apparent
reason. (False triggering)
1. Heat from LED Globe activating sensor.
Adjust lamp holders to allow a minimum gap of 40mm
between PAR38 LED Globe and sensor head.
2. Heat sources such as air con, vents, heater
flues, barbecues, other outside lighting,
moving cars are activating sensor.
Adjust direction of sensor head away from these sources.
3. Animals/birds e.g. possums or domestic
animals.
Redirecting sensor head may help.
4. Interference from on/off switching of electric
fans or lights on the same circuit as your
security floodlight. (This problem does not
always occur but a faulty switch or noisy
fluorescent light may cause the security
floodlight to switch on.
Should the false triggering become troublesome, consider:
(a) Replacing a faulty switch.
(b) Replacing noisy fluorescent tubes or starters.
(c) Connecting the security floodlight to a separate circuit
(In most cases where one or more of the above suggestions
have been carried out, false triggering has been reduced).
5. From swimming pool reflection or reflective
surface.
Redirect sensor.
6. Unit is more sensitive during colder months.
Unit is sensing moving trees, etc.
Turn sensitivity dial anti clockwise to reduce sensitivity.
Light remains on.
1. Continuously false triggered.
Redirecting sensor head may help.
2. Time is set too long.
Reduce time.
3. Unit is more sensitive during colder months.
Unit is sensing moving trees, etc.
Turn sensitivity dial anti clockwise to reduce sensitivity.
Light switches on during daylight. 1. LUX control knob is set to daylight position.
Turn the LUX control knob to desired light setting.
When setting controls in daylight
the detection distance becomes
shorter.
1. Interference by sunlight.
Re-test at night.
