DEFENDER Tricolour LED COB  
Security Light with CCT With & Without Sensor 
INTRODUCTION

Congratulations on purchasing your Martec high quality outdoor  light fitting.

For installation of your Defender CCT Tricolour  outdoor LED spotlight, please refer 

to the Fig.1
1.  Installation must be carried out by a licensed electrician and according to 

AS/

NZS

 3000

 and relevant amendments or warranty will be voided.

2.  Switch power off at the meter box and ensure that there is no power to the 

lamp.

3.  Unscrew the Front Cover Screws and then separate the light from the back 

plate.

4.  Use the back plate to mark the position of the screw holes onto your mounting 

surface. Drill the wall to a depth of about 40mm and fit the wall plugs (supplied). 

Take care to avoid drilling or screwing into concealed electrical wiring.

5.  Connect the Power Cable to the Terminal Block, see Fig.1, and ensure the cable 

is drilled through the Rubber Gasket (supplied) to maintain the fittings IP rating.

6.  Affix the back plate to the mounting surface with the Mounting Wall Screws 

(supplied) once again using the Rubber Gasket (supplied) to maintain the fittings 

IP rating.

7. Re-fit the light fitting to the back plate mounted on the wall.

Note:

Loosen knob on adjustable arm before making any adjustments to the direction 

and position of the light heads.

When power is switched on to the Defender Sensor, it will enter into a “WARM-

UP” period for approximately 50 seconds (within 1 minute) and then automatically 

change into “AUTO MODE”. Whilst in the AUTO MODE, you can then carry out a 

Walk-Test by placing the LUX control to day position (.) and the TIME control to 

minimum (-). Once the sensor receives a valid trigger signal (such as movement 

of a human body) within its set distance detection area, the lamp(s) (load) will be 

turned on for the pre-set period of time.
You will be able to determine the detection area by walking slowly.
After completing the walk-test, set the LUX KNOB to the night position to ensure 

the sensor only operates at night and set TIME KNOB to the desired “ON’ time.

ADJUSTING THE LUX CONTROL LEVEL:

The Lux control module has a built-in sensing device (CdS photocell) that detects 

daylight and darkness. (•) position denotes that the lamp(s) (load) will be turned 

on by the PIR during both day and night. ( )position denotes that the lamp(s) 

(load) will be turned on by the PIR only at night.
You can set to operate the unit at the desired level by adjusting the Lux Knob.

ADJUSTING THE DURATION TIME:

The duration time is “the length of time that the sensor switches the load ‘on’ 

after activation”. The duration time can be adjusted from (10±5) seconds to 

(4±1) adjustable minutes.Rotating the TIME knob from (+) to (-) will reduce the 

duration time.
Note: Once the lamp(s) (load) has been triggered by the PIR sensor any 

subsequent detection will start the timed period again from the beginning. 

How to change into MANUAL CONTROL MODE

1.  When the power is on, the PIR detector enters into the “WARM-UP” period for 

about 1 minute, then automatically changes into AUTO MODE.

2.  During AUTO MODE, by switching the ON/OFF main switch 2 times within 3 

seconds and then leaving the switch on, the PIR detector will automatically 

change into MANUAL MODE from AUTO MODE. In MANUAL MODE, the 

Lamp(s) will remain ON, in MANUAL MODE the PIR detector will not be 

affected by duration time and Lux control level.

3.  During MANUAL MODE, by switching the ON/OFF main switch 2 times within 3 

seconds then leaving the switch on, the PIR detector will automatically change 

into AUTO MODE from MANUAL MODE.

4.  During MANUAL MODE or AUTO MODE, by switching off the ON/OFF main 

switch over 10 seconds and then on again, the PIR detector will reset to 

WARM-UP periods.

Please note:

 the period of “WARM-UP” maybe be shorter than 1 minute.

a.  The security lamp should be wired to its own light switch only. No two way 

switching. 

Do not interconnect with other lights on the same switch. Earth connection is 

be required.

b.  Ideally the security lamp should be mounted 1.8 to 2.5m (6 to 8ft) above the 

ground to be scanned (refer Fig.2A).

c.  To avoid damage to the sensor unit- DO NOT aim the sensor towards the sun or 

the photo electric cell will be damaged

d.  To avoid nuisance triggering, the sensor should be directed away from heat 

sources such as barbecues, Air-conditioners, other outside lighting, moving 

cars and flue vents.

e.  To avoid nuisance triggering, keeping away from areas of strong 

electromagnetic disturbance.
