SOLUTION
Check that the power is switched ON at the circuit breaker/
internal wall switch.
Turn OFF the power to the unit and check the wiring
connections as per the diagram (see previous section 3).
Ensure no connections are loose.
Check the lamp. If the lamp has failed, replace. Ensure that
the lamp is seated correctly in the lampholder.
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.
The level of ambient light in the area may be too dark for
the current DUSK setting. During daylight, adjust the DUSK
control slightly anti-clockwise. When the lamp load
extinguishes, enter the detection area. If the PIR still
activates, the setting is still too high. Repeat the above
procedure until the PIR does not activate when you enter
the detection area. Refer to previous section for more
details.
Unit may be poorly located. See previous section -
‘Selecting The Location’ and re-locate the unit.
PIR sensors 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 sensor head position to ensure
trouble-free operation all year round.
