• The DUSK control determines the level of darkness required for the unit
to start operating. The setting is best achieved by the procedure below;
1. Set the DUSK control knob fully anti clockwise.
2. When the ambient light level reaches the level of darkness at which
you wish the lamp to become operative (i.e. at dusk) SLOWLY rotate
the control in a clockwise direction until a point is reached where the
lamp illuminates.
3. Leave the control set at this point.
• At this position the unit should become operative at approximately the
same level of darkness
• 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. when it is very dark). Adjust the
control slightly clockwise.
• Continue to adjust until the unit operates as desired.
• Once the unit is set up as desired, refit the top cover by aligning the
arrows (See diagram “E”) and twist clockwise until cover is secure.
8. 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 “C”).
• 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.
9. Manual Override Mode
The light can be switched ON for longer time periods by use of the Manual
Override Mode. This can be activated at night by using the isolation switch.
• Switch the isolation switch twice (OFF/ON, OFF/ON) within 2 seconds.
• The unit will now illuminate continuously until dawn or until it is
switched back into Detection Mode.
• To return to Detection Mode switch the isolation switch OFF and then
back ON again within 1 second.
