This product is suitable for indoor or sheltered outdoor use. Connected load must not exceed
maximum 2000W incandescent or 500W fluorescent or 300W LED. This unit can also be used to
control inductive load not exceeding 200W.
CAUTION: This unit circuit is surge and transient protected to IEC specification. However, if
voltage varies significantly from 230 volts, which may occur on circuits with motor loads, the sensor
may malfunction.
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

SETTING UP FOR AUTOMATIC OPERATION.
When walk tests are complete, the unit can be switched to automatic operation :
To access the controls use a knife or thin flat blade screwdriver to gently level (see diagram E) the
unit clear of the ceiling. Hold in position against the spring pressure while making adjustment.
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. 15 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:
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 (a small step at a time) rotate
the control in a clockwise direction until a point is reached where the lamp illuminates in response
to a hand moving below the unit. Leave the control set at this point.
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.
Once the unit is set up as desired, ease the unit back into position under spring pressure.
MANUAL OVERRIDE MODE
The light can be switched on for longer time periods by use of the Manual Override Mode.
This can be activated at night by using the isolation switch.
Switch the isolation switch twice (OFF/ON, OFF/ON) within 2 seconds. The unit will now illuminate
continuously until dawn or until it is switched back into Detection Mode.
To return to Detection Mode, switch the isolation switch off and then back on again within 1
second.
IMPORTANT INFORMATION : LIGHT POLLUTION & CONSIDERATE LITHTING
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
spread on all halogen floodlights can be reduced by angling the floodlight downwards on the
mounting bracket. This will also concentrate the light on your property and limit the potential
inconvenience of the light shinning into your neghbours windows etc.
Please see Selecting a Location for information on choosing the optimum location for any
security light controlled by this unit.
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. 15 minutes. Set the control to the desired setting
between these limits.

SO LUT ION
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.
