GJD OPAL XL 35 METRE EXTERNAL PIR
INSTALLATION MANUAL
PART NO: GJD020
An inconspicuous reliable 35 metre external
passive infra red detector that works in
conjunction with the GJD security lighting
controllers.
- 1 -
The Opal XL is encased in a robust high impact ABS housing. The plug in electronics
module is supported by an internal bracket which is fully adjustable horizontally and
vertically. Further protection against harsh environments is offered by a separate
polythene lens cover which conceals the angle of detection from any intruder and
totally hides the wiring.

INSTALLATION
Ensure the unit is mounted on a vertical
surface. The multifunction lens shown on
page 3 produces 9 long and 9 short range
beam patterns. When positioning the unit
remember that movement across the beams
producesthebestresponsewhilstmovement
directly towards the detector will be less
responsive.
During installation the electronics must be
protected against water, as trapped moisture
can effect or damage the unit.
1) First remove the front polythene cover
by pulling forwards, then remove the
lens module by pulling it out of the
forked bracket.
2) Drill the wall to accept the top fixing
and the lower cable entry. The holes
should be on 16mm centres.
3) Feed standard 4 core alarm cable into
lower cable entry; bare the wires and
connecttotheremovableterminalblock.
4) Always ensure when replacing the
module thatit isthecorrect wayupfor
the correct alignment of the beam
pattern. (page 3 multibeam lens data)
5) Replace the front cover with the
ventilation hole at the bottom. Ensure
thecoverengagesbothsidesoftheouter
casing before pressing firmly to locate
it securely.
6) Applythepower-theredledflashesfor
0.5 second.

At this stage the unit can be walk tested with
the front cover fitted. Adjust the range as
necessary and pan and tilt the lens module
over the field of view to obtain the correct
beam coverage and ensuring that the
detectionbeamsdonotexceedtheareabeing
covered.
TESTING THE OUTPUTS
(Alignment of the detection beams)
The range of the detector increases without
the front cover. Therefore the cover must be
fitted during ‘walk test’.
Floodlights should be positioned at the side
or above the detector 60cm (2 feet) is
recommended, provided that the detector is
notindirectradiatedheadfromthefloodlight.
The unit detects the changes in heat and
movementinthebeampatternarea,therefore
trees,shrubs,ponds,boilerfluesandanimals
should be considered when positioning the
detector. In poor environment utilise the
‘pulse count’ option on the GJD lighting
controllers.
LIGHTLEVEL:

is turned to 24 hour - this would activate the
‘S’ output for one minute after last detection
irrespectiveoflightlevel.
Increase the lux level if the ambient light
levels at night are higher than 5 lux.
