INTRODUCTION
The Dual Tech is an outdoor motion detector and alarm trigger
that uses two independent passive infra-red detectors plus a
microwave sensor module. All three sensors must trigger to
cause the detector to signal an alarm. Utilising triple detection
technology, the Dual Tech delivers precise, reliable presence
detection.
QUICK INSTALLATION
1. Mount and connect the detector following the instructions
given later in this sheet.
2. Apply supply voltage to the unit. The detection LED (blue)
ashes three times.
3. Wait approximately 2 to 3 minutes to allow the detector to
settle.
4. Press the programming button once to activate walk test
mode. The detection LED is now enabled for ve minutes.
Note: The front cover must be tted when walk testing.
The default settings are:
• Range: 30 meters
• Pulse count: 1 (always set to 1 during walk rest)
• Detection LED: off (always enabled during Walk Test)
MOUNTING THE UNIT
During installation, protect the electronics against water, as
trapped moisture can affect or damage the unit.
1. Drill the wall to accept the two xing screws, the cable entry,
and the tamper cup (if used). See Figures 1 and 2. A hole drilling template is provided.
Note: We recommend using the tamper cup on uneven wall
surfaces.
2. Remove the cover assembly by loosening the locking screw
using the allen key provided. The cover hinges from the top
and lifts out of the location slot. See Figure 3.
3. Feed standard eight-core alarm cable into the cable entry.
Bare the wires and connect 6 wires to the terminal block and
optionally connect 2 to the tamper board. See Figures 2, 4, 5,
6 & 7.
4. Screw the unit to the wall ensuring that the tamper pin is
correctly located and that the tamper microswitch is closed.
See Figure 7. To aid installation, two spare tamper feet are
provided. One is 1mm longer and the other is 2mm longer
than the tamper foot originally tted. The tamper foot is a
push t and can be removed by carefully pulling it from the
pin. See Figure 2.
5. When the detector is aligned, connected, and programmed to
suit the installation, replace the front cover and lock as
shown. See Figure 8.
MULTIBEAM ALIGNMENT & MASKING
The multifunction lens tted to Dual Tech produces seven
long range beams and seven medium to short range curtain
PIR beams. The PIR circuitry detects changes in heat and
movement in the beam pattern; therefore items such as trees,
shrubs, ponds, boiler ues, and animals should be considered
when positioning the detector.
Note: The PIR sensor is more sensitive to movement across
the beams, and less sensitive to movement directly towards or
away from the beams.
The detector module is tted with two sliding shutters to reduce
the detection angle.
The curtains are tted to the pan and tilt module as shown
in Figure 9 (shown with primary and additional curtain sliders
tted). Each section of the detector lens gives a coverage
pattern of approximately 10 degrees.
An additional set of curtain sliders is provided should the beam
pattern need to be narrowed even further, e.g. if the minimum
detection angle of 10 degrees is required.
When coverage exceeds the desired detection area, adjust the
module as required and mask off any beams, either vertically or
horizontally, to avoid unwanted detection.
Use portions of the self-adhesive silver mask applied to the
rear, smooth side of the lens as shown in Figures 10 & 11.
Always replace the lens the correct way up to ensure exact
beam pattern coverage (top of the lens is marked TOP).
When mounted at heights above 3 metres there could be a
signicant reduction in the range of detection and the target
will have to move a greater distance within the eld of view
before an alarm is generated.
Masking Congurations For Maximum Range
Figure 12 shows the pattern for the maximum range in the
optimum position (see Figure 10). Masking the top section
of the lens reduces the range to 20m.
Figure 13 shows the pattern for the minimum range (10m). In
this case masking the top section of the lens reduces the range
to 6 meters.
Figures 14 and 15 illustrates alignment recommendations for
when the detector is mounted close to a wall.
-1-
The alignment shown in Figure 14 is not recommended. If
the detector module is orientated at an angle of 90° to the
perimeter, the mounting wall may cut off short and medium
range beams. The long range beam will still detect an intruder,
however the wall can cause false alarms when heated by
sunlight.
Figure 15 shows the recommended alignment. The detector
module is orientated at a 55° angle to the perimeter. As a result,
short and medium range beams are parallel to the perimeter,
but the detection range along the perimeter is reduced to 25
metres.
PROGRAMMING
The user can individually programme a number of congurable
settings, as illustrated in the programming chart.
Programming Chart
To change any of the Dual Tech settings:
1. Press the programme button, as shown in gure 16,
for the number of the Option to be changed, i.e. once for
range, twice for pulse count and three times for LED.
2. Wait until the blue LED indicator goes off (typically four
seconds).
3. The indicator will then ash out the existing settings.
4. To change the settings for that option, press the
programme button the number of times for the required
new setting.
5. The indicator blinks twice and the changes are stored in
the Dual Tech’s non volatile memory
Example: To change the LED setting from OFF to ON:
1. Press the programme button twice.
2. Wait until the blue LED indicator goes off (typically four
seconds).
3. The indicator will then ash once, indicating the current LED
setting is OFF.
4. Press the programme button twice to change the setting to
ON.
5. The indicator blinks twice and the changes are stored in the
Dual Tech’s non volatile memory.
PROGRAMMING OPTIONS DEFINITIONS
Pulse Count
This is the number of times the unit has to detect on both of its
sensors before signalling an output.
LED
LED Off – LED disabled.
LED On – LED signals a detection.
WALK TEST
In walk test mode, the detection LED option is set to ON, and
the pulse count option is set to 1. The detection LED lights each
time the Dual Tech detects your presence.
To enter the walk test mode, press the programming button
once. The detection LED lights and pulse count 1 is
automatically selected. The unit can then be aligned.
The test mode ends automatically ve minutes after last
detection. Alternatively, press the program button three times,
or remove and then reapply power to cancel the walk test
mode.
Note: When you conduct a walk test, make sure that the
front cover is in place. Do not conduct walk tests with the
cover removed.
The range of the detector increases without the protective
front cover. Therefore the front cover must be tted to establish
the correct beam pattern. Use programming chart to adjust the
range as necessary. Pan and tilt the lens module over the eld
of view to obtain the correct coverage area.
