4. Selecting a Location
• The motion detector has number of detection zones, at various vertical
and horizontal angles as shown (See diagram “A”)
• The optimum mounting height is 2.5m (the minimum is 1.7m)
• Careful positioning of the sensor will be required to ensure optimum
performance (See diagram “A” & “B” 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
(See diagram “C”).
• Reflective surfaces (i.e. pools of water or white painted walls)
may cause false activation under extreme conditions.

5. Installation
• Ensure the mains supply is switched off and the circuit supply fuses
are removed or the circuit breaker turned off.
• An isolating switch should be installed to enable the power to be
switched ON & OFF for maintenance purposes and to activate the
manual/auto override function.
Diagram B
Diagram C
• Remove the mounting plate from the PIR by releasing one of the lugs
(left or right side) firmly grip with your hand, and slide in a downward
direction to release.
• Mark the position of the fitting holes using the mounting plate as a
template (See section 6. Mounting Installation Steps, for the different
ways of mounting the PIR). Drill out the mounting holes taking care to
avoid any joists, electrical cables or water/gas pipes that may be hidden
beneath the surface. Insert the rawl plugs into the holes.

4
• Pass the 230V 50Hz mains supply and load cables through the cable
entry points on the backing pate, ensuring the grommet(s) is used
to maintain the IP rating of the PIR sensor.
• Fix the mounting plate to the wall using the correct screws for the
rawl plugs installed.
• Terminate the cables into the terminal block ensuring correct polarity
is observed and that all bare conductors are sleeved (see section 7.
Connection Diagram).
• Ensure all connections are secure.
• Slide the main body back onto the mounting plate then pull in a
downwards direction so that it is fully engaged with the mounting plate.
• Secure the unit by replacing the screw on the underside.

8. Operation and Testing
Adjustment
• The PIR can be adjusted using a flathead screwdriver;
Walk Test Procedure
• The sensor will rotate from left to right, and tilt forward or backward.

9
• The small arrow on the underside of the sensor indicates the direction
of the main detection area.
• The adjustment knobs located on the sides of the sensor head factory
set to “Walk Test Mode” i.e. LUX set to the ‘Sun’ symbol and the
Time set to the minimum.
• Turn the power to the unit ON. The lamp will immediately illuminate
as the unit goes through its “warm-up” period. After approximately
1 – 2 minutes the lamp will extinguish. Try to remain outside the
detection area during the warm-up period.
• Adjust the sensor to point in the desired direction for best coverage.
• The unit will now operate during daytime as well as at night,
illuminating the lamp for approx. 5 seconds each time.
• Walk across the detection area approx. 2.5 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.

10
Setting Up for Automatic Operation
When walk tests are complete, the unit can be switched to
automatic operation.
• 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. 12 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;
1. Set the DUSK control knob fully anti clockwise.
2. 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.
3. 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.
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 below).
• 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.

9. Manual Override Operation
Permanent OFF
• Flick the isolation switch to the OFF position.
Pulse Manual Override Mode– For the light
to turn ON
• Flick the isolation switch at day or night, OFF/ON twice within 2.5
seconds. The PIR will then be set to activate your lamp the same night.
• The unit will illuminate continuously until dawn, or until the unit is
switched back into auto mode.
Note: The Pulse Manual Override will only operate for 1 night, then after
will revert back to auto mode.
2.5 SEC
x2
• To manually return to Auto Mode, flick the isolation switch OFF/ON once
within 1.5 seconds.

11. Troubleshooting
Problem
• Lamp stays ON
all the time
night and day.
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 section 4. Selecting a location).
10. Holiday Mode Operation
• Flick the isolation switch at day or night, OFF/ON within 3.5 seconds
to activate the Holiday mode. The PIR will then be set to operate
your lamp each night.
• The unit will now illuminate continuously until dawn, or until the unit
is switched back into auto mode.
3.5 SEC
x3
• To manually return to Auto Mode, flick the isolation switch OFF/ON once
within 1.5 seconds.

13
• 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).

14
• The Unit activates
during the daytime.
• The 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 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. (See section 8.
Operation and Testing).
The Unit may be poorly located. See section 4.
Selection a Location, and relocate the unit.
The PIR sensors are influenced by climatic
conditions. The colder the ambient temp, the more
effective the PIR will be. You may need to make
seasonal adjustments to the sensor head position
to ensure trouble-free operation all year round.
