TROUBLE SHOOTING AND USER HINTS

Light does not switch ON
when there is movement in
the detection area.

Check all connections, and fuses/switch-
es.

Check. Replace

Redirect sensor or relocate unit.

Readjust sensor angle and/or sensitivity

Redirect sensor and/or sensitivity

Adjust lamp holders to allow a minimum
gap of 40mm between PAR38 globe and
sensor head.

Adjust direction of sensor head away from
these sources.

Probably unavoidable but redirecting 
sensor may help

Should the false triggering become 
troublesome, consider:
(A) Replacing a faulty switch.
(B) Replacing noisy fluorescent tubes

and/or starters.

(C) Connecting the 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.)

Redirect sensor.

try reducing sensitivity.

Switch light OFF for at least 10 seconds,
then return to ON position.

Reduce time by turning ON TIME control
anticlockwise.

Turn light level control clockwise.

Re-test at night.

Light switches ON for no 
apparent reason

Lights switch ON during 
daylight hours. 

When setting controls in
daylight, the detection dis-
tance becomes shorter.

Light remains ON.

PROBLEM

POSSIBLE
CAUSE

SUGGESTED
REMEDY

1. 

No mains voltage.

2.

Globe(s) faulty or missing.

3. 

Nearby lighting is too bright.

4. 

Controls set incorrectly.

5. 

Sensor positioned in wrong direction.

1. 

Heat from globe activating sensor.

2. 

Heat sources such as aircon. vents, 
heater flues, barbecues, other outside
lighting, moving cars are activating 
sensor.

3. 

Animals/birds e.g. possums or 

domestic animals.

4. 

Interference from on/off 

switching of electric fans or lights on
the same circuit as your Floodlight.      
(This problem does not always occur
but a faulty switch or noisy fluores-
cent light may cause the Floodlight to
switch on.)

5

. Reflection from swimming pool or 

reflective surface.

6. 

Interference from power surges,

mobile phones, CB’s, Taxis, etc.

1. 

Wall switch is in override “ON” mode.

2. 

Time adjustment is set too long

Daylight sensor switch is set to “OFF”
position.

Interference by sunlight.

NOTE: All passive infrared detectors are more sensitive in cold weather than warm weather and 

more sensitive at night than daytime.
