Step 2
Apply the power by switching on the circuit
breaker/internal wall switch. The lamp will
immediately illuminate as the system
goes through its 'warm-up' period. After
approximately 1-2 minutes the lamp will
extinguish. Please try to remain outside the
detection area during the warm-up period.
Step 3
Walk across the detection area approx. 5
metres from the unit. As you cross the first
detection 'zone' the lamp should illuminate.
Now stand still until the lamp extinguishes
(this should take approx. 5 seconds).
Step 4
Start moving again. As you cross each
'zone' the lamp should illuminate as in
step 3.

Step 5
Repeat Steps 3 & 4, walking at various
distances and angles to the unit (see
Fig.14). This will help you to establish
the detection pattern.
Step 6
If the detection area is too small for your
requirements, try angling the sensor head
up. This should increase the coverage
distance. Similarly, angling the head
downwards will reduce the range should
a smaller coverage area be required.
For more unusual requirements (i.e. very
short range), it may be necessary to 'mask'
an area of the sensor lens to achieve the
desired coverage.
Please refer to Section 1 for details.
Step 7
Carry out Walk Tests and adjustments until
you are happy with the coverage area.
NOTE:
Passive Infra Red sensors are less
effective at detecting the movement of
vehicles, e.g. on driveways. If this is a
feature you require, some further
adjustment of the sensor head may be
required. Test by driving the vehicle in and
back out of the detection zone when the
engine is at its normal temperature.
