GJD Opal XL Installation Manual

An inconspicuous reliable 35m external passive infrared detector
that works in conjunction with the GJD security lighting controllers.

The Opal XL is encased in a robust high impact ABS housing. The
plug 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.

GJD 020 Opal XL 35m External PIR

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 produces
the best response whiles movement 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 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 xing 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 connect to the removable

terminal block.

4. Always ensure when replacing the module that it is
the correct way up for the correct alignment of the beam
pattern. (page 3 multi beam lens data)

5. Replace the front cover with the ventilation hole at
the bottom. Ensure the cover engages both sides of the

outer casing before pressing rmly to locate it securely.

6. Apply the power - the red led ashes for 0.5 second.

At this stage the unit can be walk tested with
the front cover tted. Adjust the range as
necessary and pan and tilt the lens module

over the eld of view to obtain the correct beam

coverage and ensuring that the detection beams
do not exceed the area being covered.

TESTING THE OUTPUTS

(Alignment of the detection beams)

The range of the detectors increases without the

front cover. Therefore the cover must be tted
during ‘walk test’.

Floodlights should be positioned at the
side or above the detector 60cm (2 feet) is
recommended, provided that the detector is not

in the direct radiated head from the oodlight.

The unit detects the changes in the heat and
movement in the beam pattern area, therefore

trees, shrubs, pounds,boiler ues and animals

should be considered when positioning the

detector. In poor environment utilise the ‘pulse
count’ option on the GJD lighting controllers.

LIGHT LEVEL:

The unit is set at ‘5’ lux. This is the light level that
the ‘S’ -ve output operates when detection takes

place. This is generally considered the average
light level at dusk. If the lux level dial is turned

to 24 hour - this would activate the ‘S’ output for

one minute after last detection irrespective of
light level.

Increase the lux level if the ambient light lvels at
night are higher than 5 lux.
