Lamp stays ON all
the time at night.
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.
PIR keeps activating
for no reason/
at random.
You may not be allowing the unit time to complete its
warm-up period. Stand well out of the detection range
and wait (the warm-up period should never exceed
5 minutes).
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.
PIR sensor will not
operate at all.
Check that the power is switched ON at the circuit
breaker/internal wall switch.
Turn OFF the power to the unit and check
the wiring connections as per the diagram.
Ensure no connections are loose.
The PIR sensor will
not operate at night.
The level of ambient light in the area may be too bright
to allow operation at the current DUSK setting.
During the hours of darkness, adjust the DUSK control
slowly clockwise until the lamp illuminates.
Refer to the previous section for more details.
