energy saving lamps, we suggest the TIME setting is set to a minimum of 3 minutes.
Do not attempt to install during wet weather, if you are suffering from nausea or dizzy spells or on
medication with similar side effects.If in any doubt, consult a qualified tradesperson or electrician.
SECTION TWO
SELECTING THE LOCATION
The motion detector has a number of detection zones, at various vertical and horizontal angles
as shown (see diagram A).
A moving human body needs to cross/enter one of these zones to activate the sensor. The best
all-round coverage is achieved with the unit mounted at the optimum height of 2.5m.
Careful positioning of the sensor will be required to ensure optimum performance. See diagram A
detailing detection range and direction.
The sensor is more sensitive to movement ACROSS its field of vision than to movement directly
TOWARDS (see diagram B). Therefore position the unit so that the sensor looks ACROSS the
likely approach path.
Avoid positioning the sensor where there are any sources of heat in the detection area (extractor
fans, tumble dryer exhausts etc.) including opposite any other light sources such as other
security lights.
Reflective surfaces (ie pools of water or white-painted walls) and overhanging branches may
cause false activation under extreme conditions.
During extreme weather conditions the motion sensor may exhibit unusual behaviour. This
does not indicate a fault with the sensor. Once normal weather conditions return, the sensor will
resume normal operation.
LIGHT POLLUTION
To reduce the risk of light pollution, consider the following when installing the any lights controlled
by this unit.
Position the light to ensure that the light emitted does not encroach onto neighbouring properties.
Angle the floodlight downward to focus the illumination onto the ground, not into the sky.
Consider using a lower wattage bulb to save energy and reduce high light output if not required.

SECTION THREE
INSTALLATION
After choosing a suitable location (see previous section) install the unit as follows:
The unit is suitable for connection to a 240 V ac 50Hz electricity supply. It is suggested that
3-core round flexible cable of 1mm² gauge is used. An internal switch should be installed to
switch the power to the unit ON & OFF. This allows the sensor to be easily switched off when not
required or for maintenance purposes.
This product is designed to be mounted on walls or under eaves, see diagram E. The sensor can
be rotated through 180 degrees to direct detection where required, decide on your location before
installation.
Remove the unit from its packaging.
Unscrew the wiring box fixing screw shown on diagram F. This screw is captive, do not fully
remove.
Detach the wiring box from the Sensor body.
Using the wall plate as a template, mark the position of the fitting holes.
Drill the holes. Insert the wall plugs into the holes.
PIERCE & PASS THE CABLE(S) THROUGH THE GROMMET(S) BEFORE PROCEEDING.
It is recommended that the grommet is pierced with a screwdriver to ensure a better seal.
Attach the mounting plate to the wall using screws provided. Do not overtighten the mounting
screws as this could damage the unit. If using a power screwdriver, use the lowest torque
setting.
This unit features an installation aid. Simply hang the Sensor onto the wall plate by use of the
clip arrangement on the wall plate. See diagram H. This allows you to use your hands to hold the
screwdriver, and install the incoming cables with ease.
Connect the incoming and outgoing cables as follows
*** IMPORTANT ***
Switch off the electricity at the fuse box by removing the relevant fuse or switching off
the circuit breaker before proceeding with the installation.

SECTION FOUR
OPERATION AND TESTING
WALK TESTING PROCEDURE
The sensor will tilt forward or backward. Adjust the sensor to point in the desired direction.
Set the two adjustment controls on the underside of the unit (diagram C) to the following
positions: TIME - Fully anti-clockwise
DUSK - Fully anti-clockwise
The unit will now operate during daytime as well as at night, illuminating the lamp for approx.
5 seconds each time. This allows testing to be carried out to establish the best position for the
sensor. The lamp will immediately illuminate as the unit goes through its "warm-up" period. After
approximately 1 minute the lamp will extinguish. Try to remain outside the detection area during
the warm-up period.
Walk across the detection area approx 5 metres from the unit. As you cross a detection "zone"
the lamp will illuminate. Now stand still until the lamp extinguishes (this should take approx. 5
seconds).
Start moving again. As you cross each "zone" the lamp will illuminate.
Repeat the above, walking at various distances and angles to the unit. This will help you to
establish the detection pattern.
If the detection area is too small for your requirements, try angling the sensor head up. This will
increase the coverage distance. Angling the head downwards will reduce the range should a
smaller coverage area be required.
SETTING UP FOR AUTOMATIC OPERATION
When walk tests are complete, and there is no motion detected, the unit switches to automatic
sensing.
The TIME setting controls how long the unit remains illuminated following activation & after
all motion ceases. The minimum time (fully anti-clockwise) is approx. 5 seconds, whilst the
maximum time (fully clockwise) is approx. 5 minutes. Set the control to the desired setting
between these limits.
The DUSK control determines the level of darkness required for the unit to start operating. The
setting is best achieved by the procedure below(wait for 1 minute before adjusting):
Set the DUSK control knob fully anti-clockwise. The unit will now start operating at dusk.
If you require the light to activate earlier, wait until the ambient light level reaches the level of
darkness at which you wish the lamp to become operative, SLOWLY rotate the control in a
clockwise direction until a point is reached where the lamp illuminates. Leave the control set at
this point. The unit may operate when the dusk control is adjusted.
Please wait until the unit resets before making further adjustments. if the unit operates after dusk
setting is done, stop movement for 1 minute. The unit will then settle into normal sensing mode.
At this position, the unit should become operative at approximately the same level of darkness
each evening. Observe the operation of the unit. If the unit is starting to operate too early (ie.
when it is quite light), adjust the control slightly anti-clockwise. If the unit starts to operate too late
(ie. dusk), adjust the control slightly clockwise.
Continue to adjust until the unit operates as desired.
MASKING THE SENSOR LENS
To restrict the sensor coverage, preventing detection in unwanted areas, mask the sensor lens
using the masks provided in the accessory pack(see diagram H). For your information, the top
section of the lens covers long range detection, the bottom covers short range. Similarly the left
and right lens sections cover the left and right detection areas respectively.

IMPORTANT INFORMATION : LIGHT POLLUTION & CONSIDERATE LIGHTING
Please be aware of the annoyance over-lighting an area can cause to your immediate
neighbours.
Light pollution caused by incorrectly installing a unit or over-lighting an area can be limited by
carefully considering the location and position of your unit before installation. The light spead
on all halogen floodlights can be reduced by angling the floorlight downwards on the mounting
bracket. This will also concentrate the light on your property and limit the potential inconvenience
of the light shining into your neighbours windows etc.
Please see Selecting a Location for information on choosing the optimum location for your
security light.

TROUBLESHOOTING GUIDE
PROBLEM
❏Lamp stays ON all the time at
night.
❏PIR keeps activating for no
reason / at random.
❏PIR sensor will not operate
at all.
❏The PIR sensor will not
operate at night.
❏Unit activates during the
daytime
❏PIR coverage is poor/
sporadic
❏ Detection range varies from
day to day
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 3.
Reset unit. Leave for a maximum of 5 minutes. If light
activates, check area for false activation from heat or
reflective source.
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.
Check the lamp. If the lamp has failed, replace. Ensure that
the lamp is seated correctly in the lampholder. Please note
that the unit will not detect through glass.
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.
Adjust the setting anti-clockwise to lower the level of ambient
light required for activation.
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.
