INSTALLATION:
01) Switch off the mains before commencing
installation.
02) Using the bracket as a template mark and then
drill the appropriate fixing holes.
03) Secure the bracket with suitable fixings.
04) Slot the floodlight on to the bracket and secure
the fixing bolts.
05) Terminate loose ends of wire to an appropriate IP
rated junction box or similar, ensuring the below
is observed.
Live - Brown / Red
Neutral - Blue / Black
Earth - Yellow / Green
06) Adjust the direction of the floodlight.
07) Restore mains power.
08) Adjust the PIR sensor floodlight to the desired
settings.
UNDERSTANDING THE CONTROLS:
(Please refer to Fig. 5 below)
ADJUSTING THE DURATION TIME:
The length of time the unit remains switched on
after activation can be adjusted from (10±3) seconds
to (10±3) minutes approximately. Rotating the TIME
screw 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 LUX CONTROL LEVEL:
The Lux control module has a built-in sensing device
(photocell) that detects daylight and darkness. The
(
R
) position denotes that the floodlights can work
at day and night, and the (
) position only work at
night. You can set to operate the unit at the desired
level by adjusting the LUX screw.
SETTING THE CONTROLS - WALK TEST:
Turn the Lux control screw to light (
R
) & ensure
that the TIME control screw is set at the minimum
duration time (-) position. The floodlight will now
switch on and remain on for about 10 seconds after
each detection.
01) Adjust time control to required setting.
02) To set the light level at which the floodlight will
automatically switch “on” at night, turn the LUX
control screw from daylight (
R
) to night (
). If
the floodlight is required to switch on earlier, e.g.
dusk, wait for the desired light level, then slowly
turn the LUX control screw towards daylight while
someone walks across the center of the area to
be detected. When the floodlight switches on
stop adjusting. You may need to make further
adjustments to achieve your ideal light level
setting.
ADJUSTING THE SENSITIVITY:
The sensitivity means the maximum distance which
PIR sensor can be triggered by movement - turning
the SENS knob from (+) to (-) will decrease the
sensitivity.
TROUBLESHOOTING AND USER HINTS:
Note:
all passive infra red detectors are more sensitive in cold and dry weather than warm and wet weather.
PROBLEM
POSSIBLE CAUSE
SUGGESTED REMEDY
Light does not switch
on when there is
movement in the
detection area.
1. No mains voltage
Check all connections, and MCB Fuses /
switches
2. Nearby lighting is too bright
Relocate the unit
3. Controls set incorrectly
Adjust Lux setting
4. Wired incorrectly
Check wiring and confirm its wired as per the
wiring instructions opposite
5. Sensor positioned in wrong direction
Relocate the unit
Light switches on for
no apparent reason
(false trigger)
1. Heat sources such as air-con, vents, heaters,
flues, other outside lighting, moving cars trees
or shrubs are activating sensor
Relocate the unit
2. Interference from on/off switching of electric
fans or lights on the same circuit as your
security floodlight.
(This problem does not always occur but a faulty
switch or noisy fluorescent light may cause the
security floodlight to switch on)
Should the false triggering become,
troublesome, consider:
(a) Replacing a faulty switch
(b) Replacing noisy fluorescent tubes and/
or starters
(c) Connecting the floodlight to a separate
circuit (in most cases where one or more of
the above suggestions have been carried
out, false triggering has been reduced)
3. Reflection from swimming pool, or reflective
surface such as smooth white walls
Relocate the unit
Light remains on
Time is set too long
Reduce time
Light remains on at
nighttime
Possible heat source in detection zone
Cover PIR sensor lens with a thick cloth, if
the light turns off check detection area for
heat or reflective source, reposition head and
decrease the sensitivity setting if this control
is available
Light switches on
during daylight hours
LUX control screw is set to daylight position
Turn the LUX control screw to desired light
level setting
When setting the lux
controls in daylight
the detection distance
becomes shorter
Interference by sunlight
Re-test at night
