8. Troubleshooting
Problem
• The lamp stays
ON all the time
at night.
• The PIR keeps
activating for no
reason at random.
• The PIR will not
operate at all.
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 6.
Connection Diagram).
Turn off at the isolation switch. Turn back ON again
after 30 seconds. Leave for approximately 15 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 isolation switch.
Turn OFF the power to the unit and check the wiring
connections (See section 6. Wiring Diagram).
Check the lamp. If the lamp has failed, replace.
Ensure that the lamp is seated correctly in the lamp
holder. Please note that the unit will not detect
through glass. (e.g. in a glazed porch).
