SECTION ONE

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 night-only operation.

PARTS INCLUDED

– Luminaire c/w PIR Sensor unit.
– Instruction manual. Please keep safe for future reference.
– Accessory Pack.
– 2 x 230V 75W PAR30 ES Reflector lamps

TOOLS & PARTS NEEDED

– Electric/hand-held drill & bits.
– Terminal or Electricians screwdriver
– Large slotted/philips screwdriver
– Wire cutters

Unit is for outdoor use only. Unit must be mounted on a non-flammable surface
as a fixed luminaire, and is not suitable for portable use.
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
and 1.0m in front.
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.).
Reflective surfaces (i.e. 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.

SECTION THREE

INSTALLATION

Switch off the electricity at the fuse box by removing the relevant fuse or switching off

After choosing a suitable location (see previous section) install the unit as follows:

Remove the wiring box cover by unscrewing the retaining screw (fig F) and with a screwdriver
gently push down and ease out. The unit is suitable for connection to a 230V AC 50Hz
electricity supply. It is suggested that 3-core round flexible cable of 1mm
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.

Mark position of the fixing holes. (Fig C)
Drill the holes. Insert the wall plugs into the holes.

PASS THE CABLE THROUGH THE WALL BRACKET BEFORE SECURING WALL BRACKET
TO THE WALL.

Pierce the grommet and pass the cable through the wall bracket.
Allow approximately 70mm of cable to pass through the grommet.
(A template for this wire length is provided on the rear cover of this manual).

Fit grommet into its location hole ensuring a good seal.
Fix the mounting plate to the wall. Take care not to overtighten the screws to prevent
damage to the mounting plate. If using a power screwdriver, use the lowest torque setting.

CONNECTION

This unit is supplied with a hanging attachment (tether) to aid installation.
If it is not required, simply remove from the unit and discard.

Place the round end of the tether into the keyhole shape location hole on the wall bracket.
Ensure the tether is securely fixed into the slot before releasing the weight of the unit.

The unit can now be suspended below the wall bracket. (Fig D)

Connect the cable to the terminal block as follows (see connection diagram):

NEUTRAL (Blue) N
LIVE (Brown) L

An EARTH connection will only be required if metal encased slave luminaires
which are not double insulated are to be in use.

Ensure the connections are secure.

Place terminal block onto its securing pillar on the wall bracket (Fig E)

Remove and discard the tether.

Fit floodlight to wall bracket and secure by fixing screw (Fig F)
Install the PAR 30 lamps. Ensure the fixed rubber gasket is securely fitted to cover
the metal rim of the lamp and lamp holder.

OPERATION AND TESTING

WALK TEST PROCEDURE

The sensor will rotate from left to right, and tilt forward or backward. Adjust the sensor
to point in the required direction. (note diagram B)

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).
If not, set as shown in diagram G.

Turn the power to the unit 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.

TEST MODE – 3 LEDS VISIBLE

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.

If the detection area is too small for your requirements, try angling the sensor head up.

Angling the head downwards will reduce the detection area should a smaller range

be required.

SETTING UP FOR AUTOMATIC OPERATION – 3 SCROLLING LED’S VISIBLE

When walk tests are complete, the unit will be switch into Automatic Mode.
Simply cease movement within the detection area for approximately 60 seconds, ensure the
lamp is not illuminated. The unit will then switch to Automatic Mode, this is indicated by
the illumination of three scrolling LEDS in the top transparent area of the sensor head.
These LED’s will scroll from left to right during daylight and darkness.

The TIME setting controls how long the unit remains illuminated following activation and
after all motion ceases.
(See diagram G. the time adjustment knob is indicated by the ‘Clock’ symbol).

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:
(See diagram G. 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 light) 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.
The LED’s will scroll from left to right, day and night; indicating the unit is in Automatic
Mode. The LED’s will extinguish when the PIR activates the light for as long as the lamp

is illuminated.

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.

MANUAL OVERRIDE MODE – SINGLE LED ILLUMINATED

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 internal wall switch or circuit breaker.
Switch the internal wall switch/circuit breaker twice (off/on, off/on) within 2 seconds.
The unit will now illuminate continuously or until it is switched back into Auto Mode.

Manual Override Mode is indicated by the permanent illumination of a single red LED
in the top of the sensor head.

To switch the unit back into Auto Mode, flick the internal wall switch/circuit breaker off/on
once within 1 second. The unit will return to Auto Mode. This is indicated by the return
of the left to right scrolling LED’s as described in Automatic Operation above.

HOLIDAY MODE – SINGLE LED FLASHING

The benefit of Holiday Mode is that the user can program the unit to automatically
illuminate for a certain time, (1 – 8 hours) each night. At dusk the unit will illuminate for
this set period after which it will extinguish. The unit will continue to operate normally
when it senses movement until dawn. At dusk the following night the process will
be repeated, the unit will remain on for this set period
(1 – 8 hours) then operate as a PIR unit until dawn.

HOLIDAY MODE

Switch the internal wall switch/circuit breaker 3 times (off/on off/on off/on) within 2 seconds.
A single flashing red LED at the top of the sensor head indicates Holiday Mode. The unit will
now illuminate for a user defined time between 1 and 8 hours. The time can be set by
rotating the centre adjustment knob as required. (See diagram G, the adjustment knob
is identified by the letter T inside a circle.)

Do not adjust this setting if you do not wish to use the Holiday Mode facility.
This time adjustment is factory set to 1 hour.

Please note: Fully anti-clockwise is 1 hour, fully clockwise is 8 hours.

After the defined period has elapsed, the unit will return to Automatic Mode and operate
as previously set up and the three scrolling LED’s will illuminate from left to right.

Holiday Mode will NOT reset to Automatic Mode at dawn, it will repeat each night
until reset by the user.
To cancel Holiday Mode, switch the internal wall switch/circuit breaker once (off/on)
within one second. The unit will turn to Automatic Mode indicated by the scrolling LEDs.

TROUBLESHOOTING GUIDE

PROBLEM

• Lamp stays ON all the time

at night.

• PIR keeps activating for

no reason/at random.

in resolving your query.

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. The problem may be solved by slightly
adjusting the direction/angle of the sensor head
(see previous section).

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 it’s
warm-up period. Stand well out of the detection range
and wait (the warm-up period should never exceed

1 minute).

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.

PROBLEM

• 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

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.

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. Refer to previous section for

more details.

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
load extinguishes, 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. You may need to make seasonal
adjustments to the sensor head position to ensure
trouble-free operation all year round.
