1. General Information
These instructions should be read carefully and retained for further
reference and maintenance.
2. Safety
• Before installation or maintenance, ensure the mains supply to the
PIR sensor is switched off and the circuit supply fuses are removed
or the circuit breaker turned off.
• It is recommended that a qualified electrician is consulted or used for
the installation of this PIR sensor and install in accordance with the
current IEE wiring and Building Regulations.
• Check that the total load on the circuit including when this PIR sensor
is fitted does not exceed the rating of the circuit cable, fuse or
circuit breaker.

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 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.
6. Mounting Installation Steps
Wall Mounting
• Please use the following steps for wall/surface mounting.

5
Ceiling/Eave Mounting
• Please use the following steps for ceiling/eave mounting.

6
External Corner Mounting
• Please use the following steps for external corner mounting.
• Please use the following steps to remove the PIR from the corner
mounted bracket.

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.
