Sensor information
Planning your installation
First decide on the location bearing in mind that the detector will perform best if mounted between 2 and 2.5
meters from the ground. It is also important to remember not to position the detector where it will reach areas
such as footpaths and roads as this may result in unwanted activations from passers by.
The detector responds better when a person moves across the field of vision as opposed to straight towards
it. Mounting the detector towards the side of a building with the head angles at 45 degree will make the
detector respond better than mounting in the center looking straight ahead.
The detector cannot see through solid objects including glass so care should be taken that field of view is not
obstructed by trees bushes parked cars etc.

The detector must be mounted well clear of central heating outlets or any large reflective surfaces as this may
result in unwanted activations.

Operating instructions
Test mode
In test mode the unit will activate day or night regardless of ambient light levels. Activations during the test
mode will activate the light for 5sec. The unit will progress to AUTO mode automatically after 5 mins.
Auto mode
In auto mode the unit will activate according to the settings selected on the LUX&TIME adjusters.To allow
the unit to work only at night turn LUX to “-“ or to allow unit to operate both day&night to “+”. The amount of
time the unit stays on after activation can be adjusted from between 20sec and 12min using the TIME
adjuster.
Override mode
In override mode the light will remain permanently ON until:
a) The unit is switched OFF and ON quickly.
b) The unit has been on for more than 6 hours.
c) Dawn (light level over or about 300lux) arrives when LUX control set to “-“ position.

Nothing happen
1. Check supply to unit．
Detector clicks but does not operate
1. Check lamps are not broken.
2. Check lamps tight in lampholders.
Light go on and off quickly
1. Ensure light is not being reflected back into sensor.check for white or reflective surfaces in protection
pattern.
2. Note the detector is more sensitive in cold weather.
Light stay on
1. Check unit has not gone into Manual override mode;
2. Adjust time to minimum.
3. Ensure nothing in field of view activating detector.
4. Ensure unit is firmly fixed to a solid object with no moving branches etc. in field of view.
5. Ensure detector is not being activated by stray moving heat sources such as heating outlets cars etc.
Light switch on during storms
Adverse weather conditions and temperature changes can result in unwanted activations. This can be
minished by mounting in a protected location and adjusting sensitivity control. Switch power supply off
during storms.
Fault finding
Maintenance and repair
1.Do not attempt to repair as this could invalidate warranty or result in personal injury.
2.Clean detector lens and outside casing with damp cloth.
