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 fuses/switches
2. Nearby lighting is too bright
Re direct sensor or relocate the unit
3. Controls set incorrectly
Re adjust sensor angle of control knob
4. Sensor positioned in wrong direction
Re direct sensor and/or adjust
5. Heat sources such as air-con, vents, heater flues, barbecues,
other outside lighting, moving cars are activating sensor
Adjust direction of sensor head, away from these sources
6. Animals/birds e.g. possums or domestic animals
Re directing sensor head may help
7. Interference from on/off switching of electric fan or lights
on the same circuit as your security light.(This problem does
not always occur but a faulty switch may cause the Fortress to
switch on.)
Should the false triggering become troublesome, consider: a.
Relacing a faulty switch. b. Connecting the Defender to a separate
circuit (in most cases where one or more of the above suggestions
have) been carriedout, false triggering has been reduced.
8. Reflection from swimming pool, or reflective surface.
Re direct sensor
Light remains on.
1. Continuously false triggered
Re directing sensor head may help
2. Time is set too long
Reduce time
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 controls
in daylight the detection
distance becomes shorter.
Interfence by sunlight
Re-test at night
Note: All passive infrared detectors are more sensitive in cold weather than warm weather and more sensitive at night than daytime.
f. Do not aim towards reflective surfaces such as smooth white walls, swimming
pools, etc. The security lamp scanning specifications (approximately 12 metres
at 150°) this may vary slightly depending on the mounting height and location.
The detection range of the unit may also alter with temperature change. Before
selecting a place to install your security lamp you should note that movement
across the scan area is more effective than movement directly toward or away
from the sensor (refer Fig. 2B). If movement is made walking directly towards
or away from the sensor and not across, the apparent detection range will be
substantially reduced. (refer Fig. 2C)
g. Take special caution to loosen lock nuts and screws on sensor before making
any adjustments as this will not be covered by warranty.
