Walk Test Procedure
TIME – Fully anti-clockwise (Test Mode)
DUSK – Fully clockwise
The unit will now operate during daytime as well as at night, illuminating the lamp
for approx. 5 seconds each time. This allows testing to be carried out to establish
whether the sensor is covering the required area.
The lamp will immediately illuminate as the unit goes through its “warm-up” period.
After approximately 1 minute the lamp will extinguish. Try to remain outside the
detection area during the warm-up period.
Walk around the sensor to establish the detection area.
The sensor will detect within an approximately 9 metre diameter circle from the
centre of the sensor location with a 3m ceiling.
As you cross a detection “zone” the lamp will illuminate. Now stand still until the
lamp extinguishes (this should take approx. 5 seconds).
Start moving again after 2 seconds. As you cross each “zone” the lamp
will illuminate.
Repeat the above, walking at various distances and angles to the unit. This will help
you to confirm the detection pattern.
Setting Up for Automatic Operation
When walk tests are complete, the unit can be adjusted for automatic operation :
The TIME setting controls how long the unit remains To access the controls use
a thin flat blade screwdriver to gently lever (see diagram D) the unit clear of the
ceiling. Hold in position against the spring pressure while making adjustments.
illuminated following activation & after all motion ceases. The Time control knob
at fully anti-clockwise is Test Mode, slightly adjust to above the T is minimum time
approx. 1 min, whilst the maximum time (fully clockwise) is approx. 30 minutes.
Set the control to the desired setting between these limits.
