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. 12 minutes. Set the control to the desired setting
between these limits.
The DIMMER
control determines the brightness of the lamp in the dimmed mode. Set the control
between minimum (fully anti-clockwise, 10% light output) and maximum (fully clockwise, 60%
output) at the desired level.
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.
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 to operate too early (ie.
when it is quite light), adjust the control slightly anti-clockwise. If the unit starts to operate too late
(ie. dusk), adjust the control slightly clockwise.
Continue to adjust until the unit operates as desired.
MANUAL OVERRIDE MODE
At night
, to switch the unit into manual override mode, turn the power off/on within 1
second,using the internal wall switch/circuit breaker. The unit should now enter manual override
mode until dawn when it will reset to its normal operation. The lamp will illuminate at full power
until dawn.
To reset back to Auto mode, turn off the power again and wait 20 seconds. Switch back on. The
unit will go through its warm-up cycle before resuming normal PIR operation.
MASKING THE SENSOR LENS
To reduce the sensor coverage, preventing detection in unwanted areas, mask the sensor lens
using electrician’s tape or similar (see diagram D). For your information, the top section of the
lens covers long range detection, the bottom covers short range. Similarly, the left and right lens
sections cover the left and right detection areas respectively.
