1. General information:
The unit utilises passive infrared technology to detect heat radiation of moving human bodies.
Upon detection, the lamp will illuminate for a user-determined time period.
An integral daylight sensor ensures all day or night only operation.
Parts Included
• Luminaire c/w PIR Sensor unit.
• Instruction manual. Please keep safe
for future reference.
• Accessory pack.
The unit can get very hot during use. Ensure the unit has cooled before handling.
Ensure adequate ventilation space is allowed between the unit and any object above, in front
or to either side of the unit. Suggested space is 0.5m above, 0.3m to either side & 1.0m in front.
2. Selecting the location:
The motion detector has a number of detection zones, at various vertical and horizontal angles
as shown (see Fig 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 1.8m.
Careful positioning of the sensor will be required to ensure optimum performance.
See diagram A detailing detection range and direction.
TOWARDS (see Fig 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.).
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.
Tools & Parts Needed
• Electric or hand-held drill & bits.
• Terminal or electricians screwdriver.
• Flat and philips screwdriver.
• Wire cutters.
The setting is best achieved by the procedure below:
(See Fig H, the Dusk adjustment knob is indicated by the "Moon" and "Sun" symbols).
Set the DUSK control knob fully anti clockwise. Wait until darkness falls.
When the ambient light level reaches the level of darkness at which you wish the lamp to become
operative (i.e.: at dusk) SLOWLY rotate the control in a clockwise direction until a point is reached
where the lamp illuminates. 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
(i.e.: when it is quite bright), adjust the control slightly anti-clockwise. If the unit starts to operate
too late (i.e.: when it is very dark), adjust the control slightly clockwise.
Continue to adjust until the unit operates as desired.
If you experience problems refer to Troubleshooting Guide.
If problems still exist, do not immediately return the unit to store.

6. Trouble shooting 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.
Solution
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.
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 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 and check the wiring connections
as per the diagram (see previous section 3). Ensure no connections
are loose.
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.
4. Operating and testing:
Rotate the sensor cover to reveal the adjustment knobs (Fig G).
The unit can be set up in daylight or at night. The adjustment knobs are factory set. Lux is set
to the 'moon' setting and Time is set to a minimum (fully anti-clockwise) see Fig H.
Turn the power ON. The lamp will illuminate for approximately 30 seconds.
This indicates the unit is wired correctly.
After approximately 30 seconds the light will turn off.
The unit is now in Test Mode.
Setting Up for Automatic Operation
The lamp will now illuminate for approximately 5 seconds every time movement is detected.
Walk across the detection area approximately 5 metres from the unit. Each time you are detected
the lamp will illuminate. Now stand still until the lamp extinguishes (this should take approx.
5 seconds)
Start moving again, when you are detected again the lamp will illuminate.
Repeat the above, walking at various angles and distances to the unit. This will help you to
establish the detection pattern.
3. Installation:
After choosing a suitable location (see previous section) install the unit as follows:
Connection
Connect the cable to the terminal block as follows (see connection diagram):
NEUTRAL (Blue) N
EARTH (Green/Yellow)
LIVE (Brown) L
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.
Ensure the connections are secure. Refit wall plate ensuring it clicks firmly into place.
• Unit activates
during the daytime
• PIR coverage is
poor/sporadic
• Detection range
varies from day
to day
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 turns off, 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.
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.
as a fixed luminaire, and is not suitable for portable use.
Unit is for indoor and outdoor use. Unit must be mounted on a non-flammable surface
The unit is suitable for connection to a 230 V AC 50Hz electricity supply. It is suggested that
2 gauge is used. An isolating 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.
We recommend this unit be fitted by a qualified electrician. Install in accordance with wiring and
current building regulations. Please read the instructions carefully.
Loosen up the bottom screw (Fig C). Remove wall plate by using a small flat screwdriver (Fig C) by
gently easing the wall plate outwards.

Dusk Setting (Time knob setting)
• When setting the Time knob to “D” (fully clockwise) (Fig I), the motion detector of Bulkhead
won’t function.
• The lamp will operate depending on the “LUX” level, ie Dusk to Dawn.
The TIME setting controls how long the unit remains illuminated following activation and after
all motion ceases.
(See Fig H, the Time adjustment knob is indicated by the "Clock" symbol).
The minimum time (anti-clockwise) is approx. 5 seconds, whilst the maximum time (clockwise) is
approx. 10 minutes (Fig H). 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.

Fix the unit to the wall (Fig E). Close the rubber plug after tighten the screws (Fig E). Attach the unit
to the wall plate by a sound of click, tighten the bottom screw (Fig F). If using a power screwdriver,
use the lowest torque setting.
Pierce the grommet and pass the cable through the grommet. Clamp the cable to the rear of the
unit before securing the unit to the wall. Fit grommet into its location hole ensuring a good seal.
Open the rubber plug, mark position of the fixing holes (Fig D). Drill the holes. Insert the wall plugs
into the holes.
