UNDERSTANDING THE CONTROLS FOR PIR MODEL:
ADJUSTING THE DURATION TIME:
The length of time that the light remains switched on after activation can be adjusted from 5 seconds to
5minutes. Rotating the TIME screw (+) to (-) 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 (
)
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 screw.
SETTING THE CONTROLS:
Turn the LUX control knob to light (
) position, at this stage ensure that the time control screw is set at
minimum duration time (-) position. The bulkhead light will now switch on and remain on for about 5 seconds.
Direct the sensor toward the desired area to be scanned. Adjust time control to required setting.
To set the LUX level at which the lamp will automatically switch “on” at night, turn the LUX control screw 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 screw towards the daylight (
) while someone walks across the
centre of the area to be detected. When the lamp switches on, stop adjusting.
TROUBLESHOOTING AND USER HINTS:
Note:
all passive infra red detectors are more sensitive in cold and dry weather than warm and wet weather.
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
Relocate the unit
3. Wired incorrectly
Check wiring and confirm its wired as per the
wiring diagram
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
Relocate fitting
2. Animals / birds activating sensor
Relocate fitting
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 may cause the fitting to switch on)
Should the false triggering become, troublesome,
consider:
(a) Replacing a faulty switch
(b) 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
Relocate fitting
Light remains on
Continuously false triggered
Relocate fitting
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
When setting the lux
controls in daylight
the detection distance
becomes shorter
Interference by sunlight
Re-test at night
