Solution
Cover PIR lens with a thick cloth. If the
light turns out, check detection area for
heat or reflective source.
If the light stays on, check wiring. See
Section 3.
Turn off at the internal wall switch. Leave
for 30 seconds and turn on again. Leave for
at least 18 minutes. If light activates, check
area for false activation from heat, wind or
reflective source.
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 hours 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.
