Multibeam alignment and masking
The multifunction lens fitted to the DI601AM 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 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.
Table 2 below summarizes typical masking configurations for
use when the range option is set to 30 meters.

Figure 9 note:
EN 50131-2-2 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 EN 50131-
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 EN 50131-
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.

Pulse count
Pulse count is the number of times the detector must detect a
presence before signalling an alarm.
When the pulse count is set to 1, the detector is most sensitive.
