SECTION FOUR
OPERATION AND TESTING
WALK TESTING PROCEDURE
The sensor will rotate from left to right, and tilt forward or backward. Adjust the sensor to point in
the desired direction.
Set the two adjustment controls on the underside of the unit (diagram C) to the following
positions:
TIME - Fully anti-clockwise
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 the best position for the
sensor.
Switch on the mains power. The lamp will immediately illuminate as the unit goes through its
"warm-up" period. After approximately 1 - 2 minutes the lamp will extinguish. Try to remain
outside the detection area during the warm-up period. Walk across the detection area approx 5
metres from the unit. 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. 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
establish the detection pattern.
If the detection area is too small for your requirements, try angling the sensor head up. This will
increase the coverage distance. Angling the head downwards will reduce the range should a
smaller coverage area be required.
SETTING UP FOR AUTOMATIC OPERATION.
When walk tests are complete, the unit can be switched to automatic operation :
The TIME setting controls how long the unit remains illuminated following activation & after all
motion ceases. The minimum time (fully anti-clockwise) is approx. 5 seconds, whilst the
maximum time (fully clockwise) is approx. 5 minutes. Set the control to the desired setting.
The DUSK control determines the level of darkness required for the unit to start operating. The
setting is best achieved by the procedure below:
Set the DUSK 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.
Fix the mounting plate to the wall. Take care not to overtighten the screws to prevent damage to
the mounting plate. If using a power screwdriver, use the lowest torque setting.
