Afterfinishing the installation operation, youcan adjust the working stateof
the PIR SENSOR
ADJUSTING THE LUX (LIGHT) CONTROL LEVEL:
The Luxcontrol is a built-in sensing device (photocell) that detectsdaylight
and darkness.
() position denotes the light can be turned on during daylight and night.
()position denotes the light can be turned only at nigh.
You can set to operate the unit at the desired level by adjusting the LUX
knob
ADJUSTING THE DURATION TIME:
The duration time is “the length of time that light switches ‘on’ after
activation. The duration time can be adjusted from (10±5) seconds to
(40±5) minutes. Rotating the TIME knob from (+) to (-) will reduce the
duration time. Note: Once the light has been triggered by the PIR sensor
any subsequent detection will start the timed period again from the
beginning.
ADJUSTING THE SENSITIVITY: The sensitivity means the Maximum
distance which PIR Sensor can be triggered by movement body. Turning
the SENS knob from (+) to (-) will decrease the sensitivity.
SETTING THE CONTROLS
1. Put the Lux control knob to light () position, turn the wall switch on
and wait half a minute for the control circuit to stabilize. At this stage
ensure that the TIME control knob is set at minimum duration time (-)
position. The floodlight will now switch on and remain on for about 30
seconds (within 60 seconds).
2. Direct the sensor toward the desired area to be scanned by adjusting
the swiveljointonthe sensor arm.
Important: loosen the lock nuts and screws on sensor and floodlight
before making any adjustments.
3. Have another person move across the center of the area to be
scanned and slowly adjust the angle of the sensor arm until the unit
sensors the presence of the moving person, causing the floodlight to
switch on.
4. Adjust time controlto required setting.
To set the light levelat which the floodlight will automatically switch “on” at
night, turn the LUX control knob from daylight () to night (). If the
floodlight is required to switch on earlier, e. g. Dusk, wait for the desired
lightlevel,andthenslowlyturntheLUXcontrolknobtowardsdaylight while
someone walks across the center of the area to be detected. When the
floodlight switches on, release the LUX control knob. You may need to
make further adjustments to achieve your ideal light level setting
