Troubleshooting & User Hints:
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
Redirect sensor or relocate the unit
3. Controls set incorrectly
Readjust sensor angle or control knob
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 from lamp body activating sensor
Adjust PIR sensor or floodlight to allow a
minimum gap of 40mm between floodlight
body and sensor head
2. 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
Reduce sensitivity
3. Animals / birds activating sensor
Redirecting sensor head may help
4. Interference from on/off switching of electric
fans or lights on the same circuit as your
security floodlight.
(This problem does not always occur but a faulty
switch or noisy fluorescent light may cause the
security floodlight 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 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)
5. 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 to 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 knob is set to daylight position
Turn the LUX control knob to desired light
level setting
When setting the lux
controls in daylight
the detection distance
becomes shorter
Interference by sunlight
Re-test at night
