Problem
• PIR sensor will not
operate at all.
• The PIR sensor will not
operate at night.
• Unit activates during the
daytime
• PIR coverage is poor/
sporadic
• Detection range varies
from day to day
Solution
Check that the power is switched On at
the power supply or internal wall switch.
Turn OFF the power to the unit and
check the wiring connections.
Check the lamp. If the lamp has failed,
replace. Ensure that the lamp is seated
correctly in the lampholder. Please note
that the unit will not detect through
glass. (e.g. in a glazed porch).
The level of ambient light in the area
may be too bright to allow operation at
the current DUSK setting. During the of
darkness, adjust the DUSK control slowly
clockwise until the lamp illuminates.
Refer to previous section for more details.
Adjust the DUSK Control setting anti-
clockwise to lower the level of ambient
light required for activation.
Unit may be poorly located.
See previous section – ‘Selecting a
Location’ and re-locate the unit.
PIR detectors are influenced by
climatic conditions. The colder the
ambient temperature, the more
effective the sensor will be. You may
need to make seasonal adjustments
to the detector head position to ensure
trouble-free operation all year round.
