• The PIR keeps
activating for no
reason at random.
• The PIR will not
operate at all.
• The PIR sensor will
not operate at night.
Check LED status:- If a single LED is constantly
visible, the unit is in Manual Override Mode
and will illuminate until dawn or until reset to
Automatic Mode. To reset to Automatic Mode,
switch the internal switch/circuit breaker off/on
within one second. Automatic Mode is indicated
by scrolling LEDs from Left to right. If a single
flashing LED is visible, Holiday Mode has been
selected. Switch the internal wall switch/circuit
breaker OFF/ON with one second and the
unit will return to Automatic Mode. The light
will illuminate only when motion is detected.
Automatic Mode is indicated by scrolling LEDs
from Left to right.
You may not be allowing the unit time to
complete its warm-up period. Stand well out of
the detection range & wait (the warm-up period
should never exceed 5 minutes). Occasionally,
wind may activate the PIR. Also 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.
Check that the power is switched ON at the
circuit breaker/internal wall switch. Turn OFF the
power to the unit & check the wiring connections
(See section 7.Connection Diagram). Ensure no
connections are loose. Check the lamp. If the
lamp has failed, replace. Ensure that the lamp is
seated correctly in the lamp holder.
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. (See section 8. Operation and Testing).
