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 if required.
PaRtS INCLUded
- luminaire c/w piR Sensor unit.
- instruction manual. please keep safe for future reference.
- Accessory pack.
- Tungsten halogen bulb.
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 & 1.0m in front.
if in any doubt, consult a qualified tradesperson or electrician.

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.
if the unit is mounted any higher than this, the sensor will need to be angled down slightly
to maintain coverage and forward coverage will be reduced.
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 it (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 (ie 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.
