9.0 Troubleshooting
PROBLEM SOLUTION
Lamp stays ON all
the time at night.
PIR keeps activating
for no reason / at
random.
The unit may be suffering from false activation. Cover the sensor lens
completely with a thick cloth. This will prevent the sensor from “seeing”
anything. If the unit now switches off after the set time duration and
does not re-activate, this indicates that the problem was caused by false
activation.
The problem may be solved by slightly adjusting the direction/ angle of
the sensor head (see previous section).
You may not be allowing the unit time to complete its warm-up period.
Stand well out of the detection range and wait (the warm-up period
should never exceed five minutes).
Occasionally, winds may activate the sensor.
Sometimes passages between buildings etc. can cause a
‘wind tunnel’ effect.
Ensure the unit is not positioned so as to allow detection of
cars / people using public thoroughfares adjacent to your property.
PIR sensor will not
operate at all.
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 F). 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 PIR sensor will
not operate at night.
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.
Unit activates
during the daytime.
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 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.
PIR coverage is
poor / sporadic.
Unit may be poorly located. See previous section - ‘Selecting The
Location’ and re-locate the unit.
Detection range
varies from day
to day.
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.
