uNderStaNdiNg tHe coNtroLS:
(Referring to Fig. 5 below)
adJuStiNg tHe duratioN time:
The length of time that the light remains switched on after activation can be adjusted from (10±5) seconds to
(4±1) minutes. Rotating the TIME control from (+) to (-) (clockwise) will reduce the time duration.
Note:
once the light has been triggered by the PIR sensor any subsequent detection will start the timed period
again from the beginning.
adJuStiNg tHe Lux coNtroL LeveL:
The lux control module has a built-in sensing device (photocell) that detects daylight and darkness. The (
R
)
position denotes that the bulkhead light can work at day and night, and the (
) position will only work at night.
you can set to operate the light at the desired level by adjusting the LUX dial.
SettiNg tHe coNtroLS:
01) Turn the LUX control to light (
R
) position, at this stage ensure that the time control is set at minimum
duration time (-) position. The bulkhead light will now switch on and remain on for about 30+ seconds.
02) Direct the sensor toward the desired area to be scanned by adjusting the PIR sensor, have another person
move across the centre of the area to be scanned and slowly adjust the PIR sensor until the unit senses the
presence of the moving person, causing the lamp to switch on. (Refer to Fig. 6 above).
03) Adjust time control to required setting.
04) To set the lux level at which the lamp will automatically switch “on” at night, turn the LUX control from
daylight to night (
). If the lamp is required to switch on earlier, e. g. dusk, wait for the desired environment
light level, then slowly turn the LUX control towards daylight (
R
) while someone walks across the centre of
the area to be detected. When the lamp switches on, release the lux control. you may need to make further
adjustments to achieve your ideal light level setting.

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 MCB Fuses / switches
2. nearby lighting is too bright
Redirect sensor or relocate the unit
3. Controls set incorrectly
Readjust sensor angle or control
4. Lamp blown
Check lamp functions and replace if necessary
5. Lamp not fitted correctly
Make sure the lamp is correctly seated in the
lampholder
6. Wired incorrectly
Check wiring and confirm its wired as per the
wiring diagram
7. Sensor positioned in wrong direction
Adjust angle and direction of PIR for best results
walk across beam
Light switches on for no
apparent reason (false
trigger)
1. Heat sources such as air-con, vents, heaters, flues,
other outside lighting, moving cars trees or shrubs
are activating sensor
Adjust direction of sensor head away from these
sources
2. Animals / birds activating sensor
Redirecting sensor head may help
3. Interference from on/off switching of electric fans
or lights on the same circuit as your fitting.
(This problem does not always occur but a faulty
switch or noisy fluorescent light may cause the
fitting 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 fitting 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. Reflection from swimming pool, or reflective
surface such as smooth white walls
Redirect sensor
Light remains on
1. Continuously false triggered
Redirecting sensor head may help
2. Time is set too long
Reduce time
Light remains on at
nighttime
Possible heat source in detection zone
Cover PIR sensor lens with a thick cloth, if the
light turns off check detection area for heat or
reflective source, reposition head
Light switches on during
daylight hours
LUX control dial is set to daylight position
Turn the LUX control dial to desired light level
setting
When setting the lux
controls in daylight
the detection distance
becomes shorter
Interference by sunlight
Re-test at night
