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 the unit off at the isolation switch.
Turn the unit back on again after 30
seconds. Leave for approximately 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
isolation 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 setting anti-clockwise to lower
the level of ambient light required for
activation.
Unit may be poorly located. See previous
section - ‘Selecting The Location’ and
re-locate the unit.
