SECTION SIX
TROUBLESHOOTING GUIDE
PROBLEM
• Lamp stays ON all the time
at night.
• PIR keeps activating for
no reason/at random.
SOLUTION
The unit may be suffering from false activation.
Cover the sensor lens completely with a thick cloth.
This will prevent the sensor from ‘seeing’ anything. If the
unit now switches off after the set time duration and does
not re-activate, this indicates that the problem was caused
by false activation. The problem may be solved by slightly
adjusting the direction/angle of the sensor head
(see previous section).
Check LED status:-
If a single LED is constantly visible, the unit is in
Manual Override Mode and will illuminate until dawn
or until reset to Automatic Mode.
To reset to Automatic Mode, switch the internal switch/
circuit breaker off/on within one second.
Automatic Mode is indicated by scrolling LEDs from
Left to right.
If a single flashing LED is visible, Holiday Mode has been
selected. Switch the internal wall switch/circuit breaker
off/on with one second and the unit will return to
Automatic Mode. The light will illuminate only when
motion is detected.
Automatic Mode is indicated by scrolling LEDs from
Left to right.
You may not be allowing the unit time to complete it’s
warm-up period. Stand well out of the detection range
and wait (the warm-up period should never exceed
1 minute).
Occasionally, winds may activate the sensor.
Sometimes passages between buildings etc. can cause
a ‘wind tunnel’ effect.
Ensure the unit is not positioned so as to allow detection
of cars/people using public thoroughfares adjacent to
your property.
If you experience problems refer to Troubleshooting Guide.
If problems still exist, do not immediately return the unit to store.
