TROUBLESHOOTING GUIDE
4
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
it’s warm-up period. Stand well out of the detection range and wait (the warm-
up period should never exceed 5 minutes). Occasionally, winds may activate
the sensor. Sometimes passages between building 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.
Thoroughly check that your wiring is correct according to the wiring diagram.
Be sure you allow the unit to complete its warm-up period - stay well out of the
detection area and wait (warm-up should never take longer than 5 minutes).
Check power is ON. If so, turn power OFF and check wiring is correct, and that
no connections are loose. Check that lamps in the system have not failed, and
that they are properly seated in their holders.
Ambient light level may be too high in operational area. Adjust the LUX control
slowly clockwise until lamp illuminates [See Section 4 for details].
Ambient light level may be too low in operational area. During daylight, turn the
LUX control slightly anti-clockwise. When lamp extinguishes, enter detection
area, if PIR still activates, adjust LUX further in anti-clockwise direction and
enter the detection zone again. Repeat procedure until PIR does not activate
[See Section 4 for details].
Check suitability of location - see Section 1 for advice, and reposition PIR if
necessary.
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.
REMEMBER Always ensure the mains supply to the unit is isolated before
removing covers which allow access to live parts.
