Setting Up for Automatic Operation
When walk tests are complete, the unit can be adjusted
for automatic operation :
To access the controls use a knife or thin flat blade
screwdriver to gently lever (see diagram E) the unit
clear of the ceiling. Hold in position against the spring
pressure while making adjustments.
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 in response to a hand moving below
the unit. Leave the control set at this point.
At this position, the unit should become operative at
approximately the same level of darkness each evening.
Observe the operation of the unit. If the unit is starting
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.
