Introduction & Where To Fit Your Bulkheads: Where To Fit Your Bulkheads & Installation:
The PIR sensor scanning specifications
(approximately 8 metres at 120°) may vary
slightly depending on the mounting height and
location.
The detection range of the unit may also alter
with temperature change. Before selecting a
place to install your PIR bulkhead you should
note that movement across the scan area is
more effective than movement directly towards
or away from the sensor. (refer to Fig. 2).
If movement is made walking directly towards
or away from the sensor and not across the
apparent detection range will be substantially
reduced (refer to Fig. 3).
INTRODUCTION:
The bulkhead light incorporates a PIR (passive
Infra red) sensing device which continuously
scans a preset operating zone and immediately
switches the light on when it detects movement
in that area.
This means that whenever movement is
detected within the range of the sensor the light
will switch on automatically to illuminate the
area you have selected to light. While there is
movement within range of the unit the light will
remain on.
READ THIS FIRST:
Check the pack and make sure you have all of
the parts listed on the front of this booklet. If
not, contact the outlet where you bought this
product.
This product must be installed by a competent
person in accordance with the current building
and IEE wiring regulations.
As the buyer, installer and/or user of this product
it is your own responsibility to ensure that this
fitting is fit for the purpose for which you have
intended it. Eterna Lighting cannot accept any
liability for loss, damage or premature failure
resulting from inappropriate use. If in any doubt,
consult a qualified electrician.
This product is designed and constructed
according to the principles of the appropriate
British Standard and is intended for normal
domestic service. Using this fitting in any other
environments may result in a shortened working
life.
Switch off the mains before commencing
installation and remove the appropriate circuit
fuse or lock off MCB.
This unit is suitable for outdoor use.
This product is designed for permanent
connection to fixed wiring: this must be a
suitable circuit (protected with the appropriate
MCB or fuse).
Before making fixing hole(s), check that
there are no obstructions hidden beneath the
mounting surface such as pipes or cables.
Make sure that the fixings are strong enough to
support the considerable weight of the fitting
and hold it rigidly.
The lamp must be positioned so that there is at
least 0.5m (500mm) between the bulb and any
illuminated surface.
When making connections ensure that the
terminals are tightened securely and that
no strands of wire protrude. Check that
the terminals are tightened onto the bared
conductors and not onto any insulation.
This product must be connected to earth
termination.
This product is not intended to be used by
children and persons with sensory, physical
and/or mental impairments that would prevent
them from using it safely.
IMPORTANT - Always switch off the mains power
before changing the lamp.
You are advised at every stage of your
installation to double-check any electrical
connections you have made. After you have
completed your installation there are electrical
tests that should be carried out, these tests are
specified in the current IEE wiring and building
regulations. If in doubt, consult a qualified
electrician.
WHERE TO FIT YOUR PIR BULKHEAD:
To achieve best results we suggest you take the
following points into consideration:
Do not mount on a surface that has vibration.
Ideally the PIR bulkhead light should be
mounted 1.58 to 2.5 metres (6 to 8ft) above the
area to be scanned (refer to Fig. 1 below).
To avoid damage to the unit do not aim sensor
towards the sun.
Avoid positioning the sensor unit adjacent to a
bright light source which may prevent the unit
from operating when the lux control is set to
operate in dark conditions.
Avoid nuisance false triggering by directing
sensor away from:
Trees and shrubs
Reflective surfaces such as smooth white walls
Swimming pools
Heat sources such as boiler flues

Understanding The PIR Bulkhead Controls: PIR Bulkhead Troubleshooting & User Hints:
UNDERSTANDING THE PIR BULKHEAD CONTROLS:
(Referring to Fig.5 below)
ADJUSTING THE DURATION TIME:
The length of time that the light remains switched on after activation can be adjusted from (2±0.5)
minutes to (4±1) minutes. Rotating the TIME knob from (+) to (-) (clockwise) will reduce the time
duration.
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 bulkhead light can work at day and night, and the (É) position will
only work at night. You can set to operate the light at the desired level by adjusting the LUX knob.
SETTING THE CONTROLS:
01) Turn the LUX control knob to light (R) position, at this stage ensure that the time control knob is
set at minimum duration time (-) position. The bulkhead light will now switch on and remain on
for about 30+ seconds.
02) Direct the sensor toward the desired area to be scanned by adjusting the PIR sensor, have another
person move across the centre of the area to be scanned and slowly adjust the PIR sensor until
the unit senses the presence of the moving person, causing the lamp to switch on. (Refer to Fig.
6 above).
03) Adjust time control to required setting.
04) To set the lux level at which the lamp will automatically switch “on” at night, turn the LUX control
knob from daylight to night (É). If the lamp is required to switch on earlier, e. g. dusk, wait for the
desired environment light level, then slowly turn the LUX control knob towards the daylight (R)
while someone walks across the centre of the area to be detected. When the lamp switches on,
release the LUX control knob. You may need to make further adjustments to achieve your ideal
light level setting.
PIR BULKHEAD 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 Redirect sensor or relocate the unit
3. Controls set incorrectly Readjust sensor angle or control knob
4. Lamp blown Check lamp functions and replace if necessary
5. Lamp not fitted correctly Make sure the lamp is correctly seated in the
lampholder
6. Wired incorrectly Check wiring and confirm its wired as per the
wiring diagram
7. Sensor positioned in wrong direction Adjust angle and direction of PIR for best
results walk across beam
Light switches on for
no apparent reason
(false trigger)
1. Heat from lamp body activating sensor Adjust PIR sensor or floodlight to allow a minimum gap of 40mm between floodlight
body and sensor head
2. Heat sources such as air-con, vents, heaters,
flues, other outside lighting, moving cars trees
or shrubs are activating sensor
Adjust direction of sensor head away from
these sources
3. Animals / birds activating sensor Redirecting sensor head may help
4. 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)
5. Reflection from swimming pool, or reflective
surface such as smooth white walls Redirect sensor
Light remains on 1. Continuously false triggered Redirecting sensor head may help
2. Time is set to 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
Light switches on
during daylight hours LUX control knob is set to daylight position Turn the LUX control knob to desired light level setting
When setting the lux
controls in daylight
the detection distance
becomes shorter
Interference by sunlight Re-test at night
