PIR adjustment
On the underside of the PIR housing are 3 rotary controls for adjusting the PIR settings.
SENS is the setting for the PIR sensitivity to movement
TIME is the setting for the length of time the flood light will stay
on after movement is detected
LUX is the setting for the ambient light level below which the PIR
detector will be activated.
Once installed, connected and angle adjusted as required, set all 3 of the above settings to the minimum
level (anti-clockwise). If the flood light is on, it should go out within approximately 15 seconds.
Adjust the LUX setting up until the flood light switches on, staying on for 15 seconds again.
Adjust the SENS control to the halfway position and move around in the detection area to check that the
flood light is actuated. If not, the SENS setting will need to be increased. Check also that the PIR is not
too sensitive by moving around in an area or at a distance where triggering the flood light is not
required. If it is too sensitive, reduce the SENS setting.
Adjust the TIME setting to the length of time preferred for the flood to stay on after it has been
triggered by movement within the detection area.
Finally, the LUX setting should be adjusted so that the PIR detection is only active at the required level
of ambient light for the flood light to be in operation.
Turning the dial towards the “sun” symbol sets the PIR to operate in daylight.
Turning the dial towards the “moon” symbol sets the PIR to operate only during hours of darkness.
Adjustment between these two levels is variable and can be attuned to a preferred time of day.
