Masking the Sensor Lens
To reduce the sensor coverage, preventing detection in unwanted areas,
mask the sensor lens using the lens mask sticker supplied (see diagram D).
For your information, the centre section of the lens covers short
range detection, and the outer edge of the lens covers long range.
Mask the sensor to suit your installation.
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 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. 18 minutes. Set the control to the desired
setting between these limits.
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 (a small step at a time) rotate the control
in a clockwise direction until a point is reached where the lamp
illuminates. Leave the control set at this point.
