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)
flashes 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 five minutes.
Note: The front cover must be fitted 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 fixing 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 fitted. The tamper foot is a
push fit 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 fitted 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 flues, 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 fitted with two sliding shutters to reduce
the detection angle.
The curtains are fitted to the pan and tilt module as shown
in Figure 9 (shown with primary and additional curtain sliders
fitted). 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
significant reduction in the range of detection and the target
will have to move a greater distance within the field of view
before an alarm is generated.
Masking Configurations 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.
