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.
