10. Troubleshooting
Problem
• Lamp stays ON
all the time
night and day.
• The PIR keeps
activating for no
reason at random.
Solution
Cover the PIR lens with a thick cloth. If the light
turns OFF, check the detection area for heat or a
reflective source.
If the light stays ON, check the wiring (See
section 5. Installation and Connection).
Turn OFF at the isolation switch. Turn back ON
again after 30 seconds. Leave for approximately
15 minutes. If the light activates, check for false
activation from heat, wind or a 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 it’s changeable).
If the lamp has failed, replace. Ensure the lamp
is seated correctly in the lamp-holder.
Note: the unit will not detect through glass.
(e.g. in a glazed porch).
The level of ambient light in the area may be
too bight to allow operation at the current
DUSK setting.
During the hours of darkness, adjust the
DUSK control slowly clockwise until
the lamp illuminates.
• PIR sensor will not
operate at all.
• PIR sensor will not
operate at night.
