Multibeam alignment and masking

The multifunction lens fitted to the DDI602AM 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.
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 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 to 12.
Gently lift the top and bottom edges of the pan and tilt module
to release the lens. To replace the lens, 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. There is a locating notch on the top of the
pan and tilt module that locates into the cut-out on the top of
the lens.

Item Description
1. Long range, 30 m section
2. Short/ medium range, 6 m to 20 m section
Figure 9 note: EN50131-2-2 Grade 3 compliance requires 3m
mounting height and 0º adjustment, or 1.5m mounting height
and -2º adjustment.
Figure 10 shows the side view for the mounting height of 6 m.
Figure 10 note: This setup has not been tested to EN50131-2-
2.
Figure 11 note: Mask the black marked section off for pet
alley applications up to 30 m.
Figure 12 notes: This setup has not been tested to EN50131-
2-2. Mask the black marked section off for curtain coverage
applications.
Figure 13 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 20 m.
Figure 14 shows the pattern for the minimum range (10 m). In
this case masking the top section of the lens reduces the range
to 6 meters.
