3.3 Setting up for Automatic Operation

1. When walk tests are complete, the unit can be switched to automatic operation.

2. The PIR TIMER setting controls how long the unit remains illuminated following

activation and after all motion ceases. The minimum time (fully anti-clockwise) is

approx. 5 seconds, whilst the maximum time (fully clockwise) is approximately ﬁve

minutes. Set the control to the desired setting between these limits.

3. The LUX control determines the level of darkness required for the unit to start

operating. The setting is best achieved by the procedure below:

 • SettheLUXcontrolknobfullyanti-clockwise.Theunitwillnowstart 

 operatingatdusk.Ifyourequirethelighttoactivateearlier,waituntilthe 

 ambientlightlevelreachesthelevelofdarknessatwhichyouwishthelamp

 tobecomeoperative.SLOWLYrotatethecontrolinaclockwisedirection

 untilapointisreachedwherethelampilluminates.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.dusk),

 adjustthecontrolslightlyclockwise.

 • Continuetoadjustuntiltheunitoperatesasdesired.

3.4 Masking the Sensor Lens

1. The unit is supplied with a lens mask which allows the option to reduce the range

of the sensor.

2. The lens mask simply clicks over the sensor. When ﬁtting ensure that your chosen

option is facing forwards. The engraved arrow indicates the front of the sensor.

3. Ensure that the arrow marked on the lens mask is lined up with the arrow on the

sensor. This will then give an indication of the front of the detection area (see

Diagram H).

4. Engraving on the lens mask indicates the effect on the detection range each

segment will have. These are 2m, 4m, 8m or 12m.

5. If no segments are removed then the sensor WILL NOT detect. The desired

range can be achieved by carefully removing the segments then repeating the

walk test after each segment has been removed until the desired detection area

is achieved.
