NOTE: It is advisable to use a separate  
independent wall switch to ensure the simplest 
operation of this unit. 
In normal operation when first switched on,  
the unit will operate only in automatic mode. 
The unit will not operate the lamp in daylight. 
When dark, the light will be activated by  
movement across the detection area.
•  To switch off completely, switch the wall  
  switch to OFF.

This Sensor light has a built-in photoelectric cell 
that automatically senses daylight and keeps 
the light off during daylight hours.

NOTE:

1.  This highly responsive unit may occasionally  
  activate due to rapid environment changes.
2.  To avoid false triggering do not install this unit  
  near wiring of large appliances such as  
  air conditioners, refrigerators, fluorescent  
  lights etc.
3.  When first switching on allow approximately  
  30 seconds warm up time for sensor  
  operation to settle to normal sensitivity.

During daylight hours, the unit can be ‘walk’ 
tested by turning the daylight level (“LUX”) control 
fully clockwise. Test by switching the unit on and 
walk slowly across the detection area.
Check that the light will remain on for a period  
set by adjusting the timer, from approx 10 seconds 
to 3 minutes depending on the setting after  
the last movement in the sensing area occurs.
(Refer to adjusting the daylight level and  
time delay)

First, switch off the mains power to the unit. If 
unit has been operating, allow it to cool before 
handling. Open the lamp by unscrewing the 
fasteners on the front trim and diffuser, then 
remove the diffuser and remove/replace bulb, 

(use only 240 volt a.c. ES bulb 60 watt max), 
refit diffuser. Compact fluorescent bulbs may be 
fitted in this light. 

For normal operation, the daylight level (“LUX”) 
control is set to fully anti-clockwise. For walk 
testing in daylight the LUX control is set fully 
clockwise.
If you find in normal operation that you would 
like the light to come on sooner, adjust slightly 
back from the full anti-clockwise position. See 
figure 5 below. To adjust the time delay turn the 
time adjusting arrow clockwise to increase the 
delay and anti-clockwise to decrease the 
delay. The time delay is from approximately  
10 seconds to 3 minutes. It is recommended  
to use shorter time delays.

Light does not switch ON when there 

is movement in the detection area.

1. No mains voltage.

Check all connections, and fuses/switches.

2. Globe faulty or missing.

Check. Replace.

3. Wiring incorrect.

Re-check.

4. Nearby lighting is too bright.

Redirect other lights or relocate unit.

Light switches ON for  

no apparent reason.

1.  Heat sources such as aircon. vents, 

heater flues, barbecues or very cold 

objects are near sensor.

Remove these sources if possible.

2.  Animals/birds e.g. possums or  

domestic animals.

Nil

3. Interference from on/off switching of 

electric fans or lights on the same  

circuit as your Sensor Light.  

(This problem does not always occur 

but a faulty switch or noisy fluorescent 

light may cause the Sensor Light to 

switch on.)

Should the false triggering become 

troublesome, consider:
(A) Replacing a faulty switch.
(B)  Replacing noisy fluorescent tubes 

and/or starters.

(C)  Connecting the Sensor Light to a 

separate circuit. (In most cases where 

one or more of the above suggestions 

have been carried out, false triggering 

has been reduced.)

4. Voltage surges

Nil

5.  Radio frequency transmissions from 

mobile phones, CB’s etc.

Nil

6. On during daytime.

Check daylight level (“LUX”) control is 

fully anti-clockwise.

Light remains ON .

1. Wiring is incorrect.

Recheck wiring.

2. Time delay set too long.

Turn time control anti-clockwise

To avoid dust build up and ensure proper functioning of the Sensor Light, wipe the sensor lens lightly 
with a damp cloth every 3 months. 
Care should be taken when cleaning to prevent scratching. A soft cloth or fine-hair brush should be 
used together with a nonabrasive cleaner. Do not use solvents or abrasive cleaners on any part of 
your Sensor Light.
