F1 (EN) • REV D • ISS 01MAR19
A hole-drilling template is provided.
Notes
•
Leave a minimum 10 cm (4 inches) clearance above
the top of the detector housing to allow the cover and
the detector to be positioned correctly.
•
We recommend using the tamper cup on uneven wall
surfaces.
•
When mounting the units side by side, a minimum
space of 1 m must be left between the detectors and
the detectors must not be looking directly towards
each other. No minimum space is required when
mounting the units back to back.
•
The recommended optimum mounting height for the
detector is 3 m. Whilst it is possible to mount the unit
higher, this will give a reduced detection range and
will require the detection subject to move further
through the already reduced detection area before an
activation is signaled.
2. Remove the cover assembly by loosening the locking
screw. Squeeze the sides of the front cover to release the
internal catches. The cover hinges from the top and lifts
out of the location slot. See Figure 2.
3. Use a razor knife to open a rubber seal to allow the
cabling into the unit (see Figure 4). Feed standard eight-
core alarm cable into the cable entry. Bare the wires and
connect to the top PCB terminal block (Figure 5, item 2).
4. Screw the unit to the wall ensuring that the tamper pin is
correctly located and that the tamper microswitch is
closed.
To aid installation, two spare tamper feet are provided.
One is 1 mm shorter and the other is 1 mm 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 1.
5. When the detector is aligned, connected, and
programmed to suit the installation:
a. Fit the cover to the detector base.
b. Lightly screw the locking screw.
c.
Put the top of the locking tool into the small notch on
each side of the cover, and then apply slight pressure
until the cover locks into the base, as shown in
Figure 15.
d. Tighten the locking screw.
Connecting the unit
The DDI602U-F1 includes jumpers that let you configure
internal end-of-line (EOL) resistor values, when EOL resistors
are required. Values are: 1, 2.2, 3.3, 4.7, 5.6, and 6.8 kΩ.
Figure 5 shows:
1. EOL resistor jumpers
2. Wiring points
Alternatively, you can remove the jumpers and connect a
discrete resistor directly to the alarm or tamper outputs, as
specified by third-party equipment.

Multibeam alignment and masking
The multifunction lens fitted to the DDI602U-F1 detector
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. The
microwave module detects actual movement towards or away
from the detector and is programmed to ignore any objects that
move outside of the preselected detection range.
Note:
PIR sensor is more sensitive to a movement across the
beams, and less sensitive to a movement directly towards or
away from the beams. Microwave sensor is more sensitive to
movement towards and away from the sensor.
The detector module is fitted with two sliding shutters to reduce
the detection angle of the PIR sensor only.
The curtains are fitted to the pan and tilt module as shown in
Figure 6. 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 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 9 and 10.
Gently lift the top and bottom edges of the pan and tilt module
to release the lens. To replace the module, please begin by
sliding one side of the lens into the clips on the pan and tilt
module. After one side is secure, do the same for the opposite
side. Once both sides are secure, gently lift the top and bottom
edges of the pan and tilt module and press on the lens to click
it into place.
Always replace the lens the correct way up to ensure exact
beam pattern coverage. The top of the lens is marked TOP as
shown in Figure 7.
Table 2 below summarizes typical masking configurations for
use when the range option is set to 25 meters.

Figure 11 shows the pattern for the maximum range in the
optimum position (see Figure 9). Masking the top section of the
lens reduces the range to 18 m / 59 ft. Item 1 is the microwave
coverage, item 2 is the PIR pattern.
